Most, if not all, dog parents will notice behavior changes in older dogs. These are natural and come with the aging process.
But did you know many of these behavior changes result from a medical condition?
I cannot impress upon you enough the importance of taking behavior changes seriously.
Too many people assume they’re a natural part of the aging process and do nothing. But “old age” is not a diagnosis!
Not only can this worsen a condition so much that it is no longer treatable, but your dog is likely living in pain, which is never acceptable.
Let’s look at common behavioral changes in older dogs and what to do about them.

Separation Anxiety
One of the most common behavior problems we tend to see in senior dogs is anxiety when separated from their humans.
Some dogs may experience it when away from a specific person, while others aren’t picky and show signs of anxiety only when they are separated from all people.
There are degrees of severity ranging from some barking and peeing or pooping in the house to all-out destruction.
Trust me when I say it is heartbreaking to witness.
Here is a very important fact – your dog’s anxiety starts long before you leave the house!
We’re so used to our routine when leaving, and we don’t think about all the cues we’re giving off that our dogs witness.
Where or how we put our coat on, in which order we pick up our purse and keys, etc.
Your dog recognizes the signs even before you start, and panic sets in.
Then, factor in how many people go over to the dog, give them a hug and kiss (even pick them up like a baby, as one of my neighbors does), and plain make a fuss.
When they come home, they do the same thing again.
In doing this, you are communicating to your dog that you will miss them and that this separation from them is stressful or emotional for you.
Hey, I understand that. But to your dog, this signals that it is a huge deal when you leave the house and definitely worth being anxious about.
That’s right, that’s the message you’re reinforcing.
What Do I Do?
Addressing behavior problems in older dogs like separation anxiety will take time – you won’t see a solution overnight.
But there are steps that you can take today to start working towards a resolution, including:
- Change the order you do things. For example, if you usually grab your coat and go, put it on, and sit on the couch for a minute.
- Never make a big deal out of coming and going. Just leave.
- Be sure you give your dog lots of exercise before you go out.
- How about playing some relaxing music…on low. Through a Dog’s Ear is one you should seriously consider.
- Dogs should not be left alone for hours on end. Hire a pet sitter, ask a friend or neighbor to take the dog for a walk, or sign him up for doggie daycare.
Compulsive Behavior
A compulsive behavior is something your dog appears to do repeatedly without even thinking about it, like the constant licking of a particular spot, chasing a tail, air biting, or staring at walls.
Although some medical conditions like dementia can be responsible, it’s often the result of anxiety.
If left untreated or unaddressed, anxious behaviors often develop into compulsive behaviors.
What Do I Do?
If you can identify the anxiety source (a conflict between your pets, perhaps?), you can eliminate/manage it before it becomes a compulsion.
It’s hard to say what the treatment will be as it depends on the cause.
The solution may include something as minor as a change in routine to more complicated options like medication/natural therapies or a behaviorist’s help.
Canine Cognitive Dysfunction (Doggie Dementia)
You may notice your dog wandering aimlessly, getting stuck behind doors or under tables, forgetting their housetraining, and not recognizing the familiar.
These behavior changes in older dogs could be signs of dementia.
There is no test to diagnose it. Instead, a diagnosis is made through a process of elimination.
What Do I Do?
There is no cure, but drugs such as Selgian (UK) and Anipryl (US) can help with the symptoms by increasing blood flow to the brain.
Call your veterinarian to talk about your concerns and the medical options available.
Calming music like that on the CD Through a Dog’s Ear has also worked wonders to help many dogs with canine dementia relax.
Some changes can be made to your living spaces to make your home more senior dog friendly.
This will help make your older dog more comfortable while also preventing injuries.
Increased Vocalization
Have you noticed your older dog crying at night? Is your otherwise quiet dog suddenly starting to bark, whine, or howl?
There are many explanations for this sudden change in dog behavior, including:
- Medical causes: illness, pain, discomfort, loss of hearing, dementia
- Behavioral causes: stress, separation anxiety, generalized fear, or anxiety
- Just plain attention-seeking
Before we can help our dogs, we must know the reason. This usually starts with asking yourself questions to narrow it down.
Here are some questions to help you get started:
- Has there been a recent addition to the household?
- Have you moved?
- Are you busier than usual and not spending enough time with the dog?
- Have you noticed something “off” about them lately?
What Do I Do?
If you’ve stopped spending time with your dog, they may be barking for attention. In this case, the solution is simple – spend more time with them.
If you’ve recently moved or welcomed a new family member, it is likely stress-related, and there are things you can do.
Make sure you still spend plenty of time with your dog.
Provide them a quiet area when they need to escape the hustle and bustle, and look into calming remedies or plugin pheromones to relax them.
Peeing/Pooping in the House
One of the more unpleasant senior dog behavior issues is when a previously housetrained dog starts peeing and/or pooping in the house.
I suggest you get some pee pads to save your sanity.
There are both disposable pee pads and reusable pee pads available, depending on your personal preferences.
For example, we use a reusable pad under our senior dog’s bed at night as an extra layer of protection if an accident happens.
Okay, now to the problem at hand – Peeing and pooping in the house.
Your dog is not doing this deliberately if that’s what you think. This behavior is often uncomfortable for them, too.
There are a lot of reasons why your dog is suddenly using your carpet as a toilet, such as:
- Dementia is causing your dog to forget their housetraining
- Illnesses that may cause increased thirst/peeing (kidneys, diabetes…)
- Incontinence is a common issue in aging dogs
- Mobility issues making it harder for them to go out
- Increasingly hectic schedules affecting your dog’s break times
- Showing dissatisfaction with changes in environment/schedule/new pets/people…
- If it’s only when you’re out, they may be showing signs of separation anxiety
What Do I Do?
If this list has triggered your “aha” moment and the reason has been revealed, great! You’re halfway to a solution.
Now, you need to figure out how to prevent that “thing” from affecting your dog.
If everything has been status quo, you’re probably looking at a medical issue. But don’t start panicking.
Your first stop is a visit to the vet for diagnosis, and then you take it from there.
In the meantime, you may want to take them out for a quick pee break more often, introduce them to a crate, or block off a well-protected or easy-to-clean area for them to sleep at night.
Aggression
While most dog behavior changes are inconvenient, this one can be a serious safety concern, especially for those with children or other pets in the house.
Older dogs who have been sweet and loving can suddenly become aggressive, and we’re thrown by something so out of character.
Pain is a big reason, as is anxiety, a lack of mobility (for example, he can’t get away from the annoying other dog he lives with), doggie dementia, vision loss, or hearing loss, to name a few.
Signs your dog is in pain include:
- Whimpering
- Lethargy
- Licking one spot on his body
- Difficulty getting up and lying down
- Withdrawing or not wanting to be touched
- Hiding
What Do I Do?
A trip to the vet can help solve the mystery of what’s causing his aggressiveness. If the cause is medical, a treatment plan can be put in place.
For example, if the cause of your dog’s aggression is pain, you can address the problem to relieve the pain entirely, or if that’s not an option, get started with a pain management plan.
Pay careful attention to any signs of aggression and keep detailed notes.
This information can be beneficial for your vet and also help you to recognize and reduce your dog’s triggers.
If your vet rules out medical explanations, I recommend contacting a dog behaviorist.
Fears and Phobias
As with many behavior changes, vision and hearing loss, dementia, and anxiety can all contribute to your dog’s fears and phobias (like a fear of thunder or walking on certain surfaces).
As always, a trip to your vet is the first course of action so an underlying medical problem can be identified.
It’s possible that treating the condition will eliminate or at least reduce the fear or phobia.
These behavior changes in older dogs are often overlooked or downplayed, but they can be extremely challenging and unpleasant for your dog to experience.
What Do I Do?
Here are a few things you can do to help your dog cope:
- Dogs thrive on routine and consistency, so don’t change if you can help it.
- You may like to redecorate, but your dog may not appreciate it if it involves their stuff. Leave their bowls, blankets, and beds where they’ve always been. Keep walking and feeding them at the same time as always.
- Try keeping them away from what they fear, if possible. It doesn’t mean it will always have to be this way. It might just be until the treatment kicks in.
- If they have become more sensitive to noise, calming music like “Through a Dog’s Ear” may help.
Desensitization can help overcome the fear of noises like fireworks or thunderstorms. To do this, you will play a recording of the sound (you can find it on YouTube) on super low volume.
If they don’t react to the trigger, give them a treat.
Gradually increase the volume over several days or weeks and reward them each time they ignore it.
Continue with this desensitization process until they can hear it at a normal volume without it triggering fear or anxiety.
Don’t rush it, and if they exhibit signs of stress at any point, go back to the volume level they were comfortable at and continue from there – slowly!!
Pheromone products, natural calming agents, or anti-anxiety medications may also be in order.
Destructive Behavior
Another behavior that may develop after having never seen it before is destructive behavior.
This could result from separation anxiety, boredom, or something else. However, to stop the behavior, you will have to identify the cause and address it first.
Call your vet and explain your concerns. They may be able to help with a diagnosis if there is a medical explanation.
Some questions you should answer before your vet appointment include:
- Are they destroying one particular thing or anything in their path?
- Any particular room, or are they happy to have a go anywhere?
- Does this happen at a specific time of day?
- When you’re home or out?
- Has there been any change to their exercise routine? Frequency? Duration? Type of activity?
What Do I Do?
Treatment/management options will vary depending on the underlying cause of the problem.
To keep your dog (and your things) safe, change your home environment based on what they have been going after.
If they have decided to chew your shoes all of a sudden, keep them out of reach.
Offering new and different types of toys, bones/chews, and even treat dispensing toys may help. But remember to never leave your dog unattended with anything that could pose a choking hazard.
Older Dog Chewing Suddenly
If you notice your older dog chewing suddenly, this is another dog behavior signaling that something may be wrong.
There may be a sudden increase in boredom, new or returning separation anxiety, pain, or age-related complications.
When a normally well-behaved dog starts to suddenly chew on everything in sight, consider if there has been any change in their environment or routine that could be responsible for triggering the behavior.
What Do I Do?
Once you find the cause, you can work on a solution. This starts by addressing the cause directly, like working with a behaviorist to eliminate separation anxiety or finding ways to reduce boredom.
In the meantime, there are also things you can do to manage this unwanted older dog behavior, such as:
Dog Proof the House
Put away anything your older dog may be able to get to and shouldn’t have. If they can reach it, they will chew it.
There may be no real rhyme or reason for what your senior dog decides to chew up.
They may be attracted to a pair of socks left at the foot of the bed or, ironically, that bottle of No Chew Spray you tried and left on the coffee table.
When dog-proofing the house, get down to their level and try to think like your dog. This will help you to identify where these chewable items may be.
Crate the Dog
If you can’t fully doggy-proof the house, or you have to leave for a bit during the day, keeping your older dog in a crate might be safer.
An alternative would be confining the dog in a smaller, dog-proofed area of the home.
Start the crating process by putting an old blanket your dog loves, along with their favorite chew toy, in the crate.
Keep the door open and watch as they discover the crate all on their own. It will seem less scary and forced this way.
Plenty of Exercise
Since an older dog chewing suddenly could result from simple boredom, ensure you and your dog get plenty of exercise and playtime together.
Walks are especially beneficial for older dogs to help keep their joints and muscles in great condition.
All the Right Chew Toys
Finally, make sure you have a good selection of chew toys you know your older pup will love.
Always read the labels of each product you purchase for your pup to ensure it is safe and age-appropriate.

All these tips can help with destructive chewing behavior in an adult dog while giving your pup something positive to look forward to throughout the day.
Changes in Sleep Patterns/Restlessness
Have you noticed that your dog, who once slept peacefully throughout the night, is now struggling to enjoy a good night’s sleep?
Restlessness, pacing, and changes in sleep patterns could stem from:
- Confusion caused by doggie dementia
- Pain (like arthritis)
- The need to pee more frequently
- Vision or hearing loss
- Your dog has started sleeping more during the day and is now restless and active at night – possibly the result of boredom
A visit to the vet will answer the “why,” and then we can focus on what we can do to help address the situation.
What Do I Do?
You may want to confine your dog to an area away from your bedroom at night so your sleep isn’t disturbed, or conversely, sleeping in your bedroom may give them comfort.
It could be a case of trying one and seeing how it works.
Increasing the amount/frequency of walks or playtime during the day and evening (within their abilities, of course) can be the solution.
You can also help to wear your dog out by introducing more mental stimulation from interactive toys or a fun training session.
Adjusting to Interlopers in the House
Before you run out and adopt a new dog, consider whether or not your senior would be happy about it.
You may think they need a friend, but they may be happy on their own, living a quiet life.
If, for whatever reason, you insist, think about your dog’s needs, likes, and dislikes. Take your time to find the right match.
If your dog has mobility issues or is not as sociable as they used to be, a puppy or high-energy dog will not be the right fit.
Behavior Modification for Dogs
Whether it is your dog’s aggression, a bad chewing habit, or another destructive behavior, you may find behavior modification necessary.
The proper behavior modification techniques can help with these issues and more.
Training is vital in stopping these behaviors. Positive reward-based training teaches even your old adult dog that they get rewarded when they do good and do what we ask.
Exercise is also a great way to help a dog release any pent-up energy and keep your senior dog stimulated.
Dog-proofing the house is also essential in curbing bad behavior.
Final Thoughts: Behavior Changes in Older Dogs
Your older dog may be more easily stressed, have lower tolerance levels than they used to, need more alone time, or have a medical issue.
It’s up to us to identify the cause of any sudden change in dog behavior and address it accordingly.
Ensure changes to their routine are done gradually, exposure to stressors is minimal, and any concerns are quickly brought to a vet’s attention.
You can still have many quality years together with timely medical care and ensuring your dog’s needs are met.

Tonya Wilhelm
Wonderful post! As a dog trainer, I’m often contacted about change in a dog’s behavior as they age. Even though the behavior or medical issue needs to be addressed, dog parents are relieved to know it’s age vs something they have done.
Hindy Pearson
Thanks Tonya. I’m encouraged hearing that many pet parents are looking for answers about behaviour changes they’re seeing. That’s so much better than chalking everything up to aging and doing nothing.
Lola The Rescued Cat
Such an informative post! I’ve been hearing more about dementia in pets lately and it’s very interesting.
Hindy Pearson
Thanks. Dementia is not something I would wish on anyone, 2 legged or 4. It’s tough to watch your dog circling for hours on end, worried she may be in pain. Thankfully there is a medication that helps, but it’s not a cure. I’m always banging on about pet parents going to the vet whenever they notice any behaviour changes, no matter how slight. The sooner a problem is diagnosed, the sooner it can be treated, or at least managed. That of course includes catching dementia before it’s so far advanced there’s not a lot that can be done.
Joely Smith
Thank you for this! Our Lyla is getting up there in age and I am always on the lookout but this gives me direct things to look for!
I am scheduling her a well pet visit this coming week. Better safe than sorry!
Hindy Pearson
That’s a great idea to have a wellness check. I watch Red like a hawk, and if anything is slightly off my radar lights up. Better safe than sorry is right!! Good luck I hope Lyla passes with flying colours.
Cathy Armato
This is such good information, Hindy! It’s scary when suddenly your pet becomes anxious or confused. That happened to my cat, I hope my dogs don’t have to go through it.
Love & biscuits,.
Dogs Luv Us and We Luv Them
Hindy Pearson
Thanks Cathy. It’s really awful to witness, I see that with Red sometimes and she’s blind so it’s even worse. No reason to worry anything will happen to the dogs, think positive instead of worrying like I do!
Tenacious Little Terrier
Mr. N has separation anxiety but he’s had it for quite a while. He has several of the risk factors though. He’s slowly improving.
Hindy Pearson
Separation anxiety can be tough on everyone, glad to know he’s doing better.
The Daily Pip
We saw many of these changes in our dog, Pip, in the last year or so of his life. Definitely a little doggie dementia as well as some compulsive behavior and restlessness. So painful to watch …but you have provided such great resources. I will feel much more prepared if Ruby ever faces these issues in the future.
Hindy Pearson
That’s what sucks about our pets getting older, although we should be grateful they do get older. It can be very tough to watch, I’m experiencing that with Red right now. It seems like her dementia is starting to act up, and there’s not a lot that can be done. We just have to make sure we’re always focused on doing what’s right for them. Hopefully Ruby will be fine for many years to come. It is comforting to know there are plenty of animals who stay relatively healthy throughout their lives.
Jane
This is a great list to refer to as our dog ages and to keep these behavior changes in mind. I have one dog who is heading into his senior years and starting to loose his vision. He does not like playing with the younger dogs much any more and will get a little snarly if they invade his space.
Hindy Pearson
Thanks Jane. I can’t emphasize enough how important it is to be aware of behaviour changes, and seeking vet help as soon as we notice any, no matter how slight. Sorry to hear about your dog. Is there anything the vet can do to stop his vision loss progressing? Hopefully the young ones will take the hint and socialise on your older dog’s terms!!
Kitty Cat Chronicles
Our senior girl Lucy unfortunately suffers from a couple of these behavior changes as she’s gotten older (she will be 17 in May). She has separation anxiety, though it’s not so severe that she is destructive. She just cries when we leave her at home, and if I go into a room and shut the door without bringing her in with me, she cries at the door. She also goes through periods of time when she goes to the bathroom in the house. This is partly because she has to go more often, and we had to make the adjustment to let her out more often. I think she may be a bit senile too, so she sometimes forgets to let us know when she needs to go out. Thanks for this helpful information!!
Hindy Pearson
Happy early birthday to Lucy!! Poor baby, separation anxiety can be very difficult to watch in our pets, as is aging in general when problems start to crop up. That’s the hard part about sharing our lives with pets isn’t it? You actually manage to close the door? Sometimes I wonder why we even have any, because as soon as one is closed someone is there scratching to get in. The fact they were nowhere near that room when the door was open makes it even funnier.
Sarcastic Dog
As Zora approaches her 14th birthday next month, I am starting to notice more mobility/pain, vocalization (mostly when I’m upstairs) and cognitive issues. I was really worried when she started having some balance issues so I did take her in for a complete neurological exam. The vet said that most of what we are seeing is old age related so we are managing her arthritis pain and her mood and appetite are really good, which is encouraging. I really appreciate your point about being very careful to introduce a new pet during this stage of life. As always, thank you for such a thoughtful and informative and supportive post.
Hindy Pearson
Happy birthday to Zora!! Wow so many of us are climbing into the same boat when it comes to issues with our seniors aren’t we! It’s definitely encouraging she has her appetite, I know with Red if she ever loses interest in eating it’s time to panic. I’m glad you found the information helpful, I do my best to offer as much helpful information as I can, for anyone lucky enough to share their life with a senior pet.
Robin
I totally agree – all changes in a pet’s life should be investigated. There are things that we can’t control as our pets age, but in so many cases there are treatments available to help our pets. A lot of illnesses have symptoms that look the same too. You just don’t know what is going on until you get a thorough examination.
Hindy Pearson
I couldn’t agree with you more Robin, if only more people realised the importance of investigating all changes. As you said, there are plenty of things we can’t do much about, but by the same token many conditions can be treated/managed, especially if caught early enough.
Sweet Purrfections
I honestly haven’t thought about dementia in pets until reading more posts and watching tv shows. Thanks you for sharing this information.
Hindy Pearson
Until Red started pacing and not being able to settle, I knew nothing about dementia, I don’t even know how I thought of it since I had never read about it or known anyone who had a pet that suffered from it (at least that they were aware of). It’s heartbreaking to watch an animal suffer from it, so the earlier it’s diagnosed the better chance it can be managed, at least for awhile.
Jenna Hughson
I find so many pups are being diagnosed with anxiety and things like that lately. Its sad but at the same time I am glad it is starting to be better diagnosed.
Hindy Pearson
I wonder why so much anxiety. Pet parents not knowing how to care for their pups? Not enough training?
Nelda
I wonder why he wants to eat non-stop. She would hurt you for food. She was never like this before.
Bren Pace | Pibbles & Me
Simply amazing post! I have an 8 year old and 9 year old and have noticed little changes. My 9 year old we just adopted last year so we really don’t have much to base it on. However, my younger guy was rescued at 1.5 years old. He’s always had some sort of dysfunction but I have noticed a few smaller things creeping in. Thankfully, we are very proactive with changes and consult with our vet.
Thank you for sharing this! Pinning it!
Hindy Pearson
Thanks so much, very kind of you to say and I appreciate you sharing!! I love hearing you adopted an older dog, fantastic. I know what you mean about having no background info, it’s really like starting with a blank canvas and learning as we go. It’s good you’re so proactive and keep in touch with your vet. Personally I don’t mind being considered a pain, as long as I keep my pets healthy.
JessaR
Great article. I was a service dog trainer, trained dogs and re-homed them to those in need. My personal Diabetes Alert Dog is the first one to have grown old with me. She went from my personal super girl to refusing to follow basic commands and ignoring me. 10 for a GSD is getting up there, and the more I read, the more I realize she is ready to retire and relax, and “arm chair coach” the puppy on how to do her job. Her hips hurt and she is tired and not rebeling. Hard to except, but she has saved my life countless times, so whatever she needs.
