What To Do If Your Old Dog Is Going Blind

What to do if your old dog is going blind


I understand the panic you must be feeling now that you suspect your dog is going blind.

The first thing I recommend you do is make an appointment with an eye specialist, since typically your regular vet won’t have the experience or equipment to properly diagnose what’s going on.

You will probably need a referral from your vet to see a specialist, so explain to the staff why you feel the situation is urgent, and get things moving so no time is wasted. 

Okay you have an appointment now you can carry on reading.

Please Help My Dog is Going Blind

Vision problems can be tough to catch early, even if our dogs are showing us there’s a problem.

Sometimes they are so subtle or come on so gradually we don’t even realize something is going on.

Here are signs to watch out for. 

20 Signs Your Dog Might Be Going Blind


1) Walks on objects or surfaces he would normally avoid

2) Rubs his face on the ground

3) Eyes are bulging

4) Cloudy eyes

5) Stepping high – like he’s unsure when walking

6) Closed eyes

7) Discharge

8) Sleeping more

9) Bumps into walls, furniture

10) Can’t catch toys you throw at him

11) Tearing

12) Redness

13) Rubbing his eye

14) Confused/disoriented

15) Is startled when approached 

16) Having trouble finding his toys/food/water bowls

17) Doesn’t want to go out at night

18) Walking slower than usual

19) Not interested in walking as much 

20) Aggressive when he never was before

Oh No, I Missed the Signs!


Once a vision problem has been diagnosed we can easily look back and think “oh now I understand why he…” but at the time there were lots of “logical” explanations.

The thing is, if this is your first time sharing your life with a blind senior dog, how can you know what to look for?

Do not beat yourself up. We’re all brilliant in hindsight, but if you don’t know you don’t know, and you can only do the best you can with the information and experience you have in that moment. 

Be Watchful!

This is something I talk about frequently, so it’s time for me to mention it again!!

If you notice any changes in your dog’s behavior – even if it’s something you consider too minor to bother your vet about – make the call anyway. You know your dog best so if you’re concerned, there’s most likely a reason to be.

Things can go downhill quite quickly, and definitely when it comes to sight, so it’s best not to adopt a “wait and see” attitude. 

How do I know if my dog is going blindHere’s An Easy Experiment to Do at Home


Move a couple of pieces of furniture, turn off the lights and watch how your dog gets around. Does he know where he’s going, or is he bumping into things?

Now turn the lights back on and watch again. If he’s completely blind, you see the same results. If he has some vision, he’ll perform better in the light.

My Two Experiences with Old Blind Dogs 



The first dog I had with vision problems was Josephine. She was an older dog my husband and I fostered…and kept of course.

Not only was this sweet soul deaf, she was also only able to see shadows. She got on very well, could always find her way to her food bowls and the front door.

She certainly didn’t need great eyesight to find her way into the kitchen when the chicken was boiling!!!

I remember the second she lost what little sight she had. We were in the car coming back from a visit with the vet at the shelter, when all of a sudden she started to howl…loudly. She was afraid of the car so would bark anyway, but I instinctively knew there was something very wrong.

We got home, I brought her into the house and after watching her I realized she had gone completely blind in that split second. She cried for about a week before she was able to start adjusting, but boy was that heartbreaking.

The worst part was, my husband was her favorite person but he was working in England at the time and we were in Florida.  

She was never the same after that, and with other health issues affecting her quality of life we said goodbye about a year after that episode. 

Talking about being brilliant in hindsight – I should have said goodbye to Josephine sooner. 

What should I do my dog is going blind


Red, my 17ish year old Chihuahua/Min Min who is featured so prominently throughout this site, and in the picture above, gained her wings May 18, 2018.

She was totally blind when we met at the same shelter Josephine came from.

Red was about 8 when we got her, with eyes so big they were literally bulging out of her head.  

After we brought her home we took her to an eye specialist hoping her blindness was reversible, which sadly wasn’t.

We were also told her eyes were bulging because of the pressure building up due to glaucoma, a condition that had been ignored by her previous owners.

Immediate action was required due to the severity of her condition, and the amount of pain she was in. Red was such a good natured dog, you’d never believe she was experiencing any level of discomfort.

Waiting much longer would have meant her eyes would have blown out of their sockets…literally.

The terrible state of her eyes and her obesity shows how terribly neglected she had been. 

We were given two options for dealing with her eyes. One was to remove them completely, the other was a procedure that involved inserting a needle into each eye to relieve the pressure.

It was several years ago, and I no longer have Red’s medical records from that time, so I have no idea if they were just needles or medication was injected as well. 

I didn’t love the idea of having her eyes removed, although if that had been my only option I would have taken it, but chose instead to go the “needle in the eye” route. I was happy with the decision and the results.

In no time her eyes started to get smaller, and they continued to shrink for years after.

Red was blind when she was dumped in the shelter, and obviously for quite some time before that.

She had a lot of time to get used to it, and she did very well. I always marveled at how well she got around new environments, and how easily she would find her water bowl.

We also took her on more trains and buses than I can possibly count, and she was a relatively frequent flyer for awhile as well and she adapted no matter where we went.

What Can Cause a Dog to Lose Their Sight? 

Nuclear Sclerosis or Lenticular Sclerosis

Have you ever looked into a dog’s eyes and noticed they appeared cloudy, a bluish haze? Although many people assume that’s cataracts, most of the time it isn’t.  

What is it?

  • Result of age related changes to the lens
  • Often seen in dogs over 7 years old
  • Usually develops in both eyes at the same time
  • Isn’t painful

How does it happen?

The lens, which cannot expand, is made up of clear fiber cells that constantly grow.

In young dogs the lens is clear, because there is plenty of room for new cells. As a dog ages, the new cells push the old ones towards the center of the lens, hardening it and causing it to cloud over.


No treatment

Living with it

Doesn’t affect vision in any significant way, although your dog may find it a little difficult to see things close to them. All in all, your dog should get along fine.

To learn more ⇒ Lenticular Sclerosis in Dogs

To learn more ⇒ When Your Pet’s Eyes Turn Cloudy, Should You Be Concerned?


Like Nuclear Sclerosis, cataracts cause cloudiness, but unlike it, cataracts affect vision. Thankfully, it is not a painful condition.

How does it happen?

Changes start in the center of the lens, then move outwards. Vision suffers as  the lens becomes more and more opaque.

Cataracts due to old age tend to develop in both eyes, but may progress at different rates. 

Cataracts can develop as the result of trauma, infection, diabetes, or hypothyroidism – low thyroid function. Inherited conditions are the most common cause.

When does it usually happen?

Cataracts generally first show up at 6-8 years of age, but can be found in very young dogs as well.

Diagnosing cataracts

A check up is needed for confirmation. 


The only real treatment is surgery, but not if cataracts are the result of a secondary disease like diabetes. By the time many pet parents notice, a large portion of the eye will have been affected.


To avoid cataracts caused by diabetes, keep your dog at an ideal weight. Overweight dogs are at risk of developing this disease. Having said that, diabetes can strike dogs of any size.

Simply put, Glaucoma is pressure caused by a buildup of fluid in the eye.

Left untreated, the optic nerve and retina are damaged beyond repair, leading to partial or total loss of vision. Glaucoma is quite a painful condition, and the most common cause of blindness in dogs.

If this condition goes untreated for even 48 hours it may be too late to save the sight in that eye, and when one eye has it, the other usually gets it.

A common symptom is the sudden development of a red, painful eye.

There are two types of Glaucoma – Primary and Secondary

Primary Glaucoma

The fluid is not able to drain through the filtration angles of the eye, and is genetics based.

I read this very sobering statistic, once again emphasizing the need to act quickly. Over 50% of dogs with primary glaucoma will develop complications in their unaffected eye within about 8 months.

Symptoms include:

  • Blinking
  • Cloudiness in the eye
  • Eye is shrinking into the head
  • Redness of the blood vessels in the whites of the eyes
  • Bulging eyes
  • Obvious sight loss

Secondary Glaucoma

This occurs after some other eye problem – trauma, slipping of the lens, inflammation, injury that caused blood to collect in the front of the eye…

Symptoms include:

  • High pressure in the eye
  • Redness of the blood vessels in the whites of eyes
  • Cloudy
  • Loss of appetite
  • Not interested in playing
  • Constriction of the pupil

Diagnosing Glaucoma

Take your dog to the eye doctor!

It’s entirely possible your vet has all the equipment needed to diagnose glaucoma and medications to treat it, and he may be fully qualified to perform as an eye doctor, but I can’t speak to that.

In my case, when we adopted Red who was blind, we went straight to a specialist. Our vet was wonderful, but going to him first wouldn’t have wasted time, and in some cases that extra time could impact the outcome.


Depending on the condition of the eyes, and the test results, your vet/eye doctor will discuss with you the options available.

It could involve drugs, draining fluid, surgery, possible removal of your dog’s eyes, and I’ve even seen natural options mentioned.

Prosthetic eyes could replace the damaged ones, or the eyelids sutured shut. I know it sounds gruesome, but I have been assured by the eye doctor we went to, dogs can live with it.

How can I tell if my dog is going blind



I touched on cataracts briefly above, but since I’m mentioning diabetes specifically it’s important to be aware that within 9 months of a dog being diagnosed with diabetes, 3 out of 4 will develop cataracts and go blind.

Cataracts can develop, literally overnight, and if they’re not treated glaucoma develops, which is an extremely painful condition.

Here is a piece of very helpful advice I read – As soon as your dog is diagnosed with diabetes, head straight for the eye doctor. Yes start diabetes treatment, but don’t wait until it’s under control because by that time it might be too late to save your dog’s eyesight.

This article”Cataracts, Blindness, and Diabetic Dogs” goes into a lot more detail, but it’s worth taking the time to read it. 

Sudden Acquired Retinal Degeneration Syndrome, or SARDS


A not very well known cause of sudden blindness in dogs is something called SARDS. Most often diagnosed in dogs around 8 1/2 years old, the cause is not known or understood.

An article I read recently called “What Causes Sudden Blindness in Older Dogs?” will give you more information about this condition. 

Eye irritants and other issues


Dust, sand, and other foreign bodies affect dogs of any age. If you notice your dog blinking a lot, tearing, rubbing his eyes, unable to open his eye(s), call your vet (or eye doctor) right away.

Ask what you can do immediately at home, then get him down there as soon as possible.

It doesn’t take long for a minor issue to affect vision.  

How to help your blind dog adjust

If your dog goes blind gradually, you might not even realize it for quite some time.

They know their homes and territory so well they don’t seem to struggle. Other senses become more acute, and they adapt rather well.

However, if a dog goes blind suddenly it can be very scary and traumatic for everyone, and it will take time to adjust. 

great way to protect your blind dog's head

Blind Dog Proof Your House


The picture you see above is a piece of foam I cut down the middle, then put on every door, table and chair leg and Red’s head height. In case she banged into something she wouldn’t hurt herself.

Similar to a pool noodle, this was purchased at a DIY store like Home Depot. 

Don’t move furniture around.

Get down on the floor and see your house from your dog’s eye level. Are there doorknobs or handles sticking out that can hurt him? Sharp edges of a coffee table? Cables he can trip over? 

Don’t leave anything on the floor he can stumble over – toys, shoes…

Put baby gates (UK shoppers click HERE) at the top and bottom of the stairs. 

Do the same around your garden. If you have a pool either fence it off, or don’t let your dog wander in the yard alone.

Any holes in the grass he can get his foot caught in? Sharp pieces of fencing sticking out?

How do I figure out if my dog is going blind

A New Way to Approach and Communicate


Over time other senses will become more acute, and while adapting to these changes your dog can become very fearful or anxious.

You may want to consider giving her something for her anxiety, at least until she adapts. Some of your options include – 

Adaptil plug in (US shoppers, UK shoppers)

Calming Bites(US)

Valerian UK

Rescue Remedy (US shoppers, UK shoppers)

I never picked Red up when she was sleeping, because I didn’t want to startle her. If I needed to wake her, which was unusual, I would call her name or stand close to her until she sensed me. 

I taught her the word “careful” and it’s a very handy cue for a blind dog to know. It’s simple really – whenever Red got too close to banging her head for example I would say “careful” and she would switch directions.

Obviously it took a bit of time for her to learn that, but she did.  It’s also a good opportunity to do some retraining. I use careful but you can just as easily remind your dog of the “sit” and “stay” command to accomplish the same thing. 

Talk a lot more to your dog in a calm voice. Make her feel safe and let her know what’s going to happen.

Let her know in words that you’re going for a walk, or that it’s time to eat. 

When you want your dog to “come”, you will likely have to repeat that cue several times to give him a chance to follow the sound of your voice. 

Your Blind Dog Can Still Play and Have a Great Life


Of course your dog becoming blind going to be a big adjustment for everyone, including your dog, so help her by keeping her active and an important member of the family.

If she always loved her toys make sure she still has access to them, but you may want to try a few different types to see which ones she prefers now.

Toys that make noise and dispense treats are all good options to try.  

She’ll still need her walks and will rely on you to guide her at the beginning.

She may have enjoyed her runs off leash, but you’ll have to keep her on leash now.

If you’ve always used a flexi leash it’s time to switch to a 4′ or 5′ leash and keep her close to you, on one side.

As she becomes more familiar with her surroundings and more confident, you could buy a super long training lead or rope to let her get some distance for a bit of a run while staying safe. 

If possible take her out when it’s relatively quiet so she’s not too overwhelmed by all the sounds outside. 

In Conclusion


It’s my hope you enjoyed this article  – maybe enjoyed isn’t the right word – let’s say found it helpful.

Any concerns relating to eye problems in dogs, please see your vet but preferably an eye specialist ASAP. 

Do you share your life with a blind dog?

Was she born blind, blind when you rescued her or something that developed as a result of illness or injury?

    Hi Hindy,
    Wow, there is a lot to learn when taking care of an older dog. It is great that you have provided us with such in-depth information so we can monitor our pets if we need to. This post is very helpful, and the vision test with using light to check your dog’s eyesight is very easy and will help so much. Thank you.

    1. Hindy Pearson (Post author)

      Hi Heather, Thanks for taking the time to comment – it’s much appreciated. My goal with this site is to provide people who care for senior dogs with as much help, advice and tips as I can. What matters most to me is that older dogs are as comfortable as they can possibly be, in the final years of their life. I’m so glad you fount it helpful.

  2. Ches

    Hi Heather, This is a subject close to my heart as I’ve recently lost both of my lovely dogs, a brother and sister. Both of them lost a lot of their sight and both of them went quite deaf, to such a degree that they couldn’t hear commands anymore. This blog is very comprehensive and covers everything to do with the care of an elderly dog, especially their failing eyesight. My dogs lived to 17 years, not a bad age. Thanks for the site it’s very informative. Ches

    1. Ches

      Sorry Hindy, got your name wrong. Ches

      1. Hindy Pearson (Post author)

        Hi Ches, No problem, thanks for correcting that! I’m very sorry to hear about your dogs. 17, wow! You’re fortunate to have had them for so many years. I know how devastating it is to lose your pets, haven’t been down that road too many times myself. It’s one thing to lose one sense, but to lose almost two is tough. I had a deaf and blind dog and it just doesn’t seem fair does it? I’m glad you enjoyed the blog, and found it thorough. I’m just getting started with it really, and my goal is to make it a comprehensive site for anyone sharing their life with a senior dog.

  3. John

    I agree that you have plenty of very useful information on here. I’m not a dog owner, but I know how much effort it can take to raise a pet. It’s nice to have people like you to provide help to those struggling to alleviate their dog’s vision problems.

    1. Hindy Pearson (Post author)

      Hi John, Thanks for commenting, and so glad you found the information helpful. I’m doing my best to provide as much useful information as I can to help people care for their senior dogs.

  4. Maureen

    Thanks for the useful and helpful information concerning eye health of our senior dogs. I have had many dogs but have never experience eye problems. Dogs tend to get the same diseases that we do so you are so right when saying we need to keep a close eye on our dogs for any signs of a health issue.
    I have a tendency to run my hands over our dog almost daily searching for anything out of the ordinary.
    On another dog of ours we found the tiniest lump on his neck and took him to the vet only to find out he had cancer. Since we caught it early he underwent treatment and survived and lived many years after.
    Our dogs are part of our family and should be treated as such.
    Thanks for the great info.

    1. Hindy Pearson (Post author)

      Hi Maureen, I appreciate you taking the time to comment, and I’m so glad you found the posts informative. That’s a great “ritual” you have going – takes seconds but, in your case, those seconds literally saved your dog’s life. Thanks for sharing that, and hopefully others reading this will incorporate that into their dog’s daily routine.

  5. Samantha

    Thank you for such an informative post! I’ll be sure to remember to watch out for these things as my dog gets older.

    On another note, what breed was Josephine? She looks exactly like my dog, who is a mutt, and so I’ve never seen a dog who looks so much like her before!

    1. Hindy Pearson (Post author)

      You’re very welcome. I love writing about senior dogs and how to care for them. It’s nice to know my experience is helping others. I don’t know exactly what Josephine was. We adopted her as quite an old lady, and of course the shelter staff didn’t know. They just referred to her as a Shih Tzu – but who knows what else was in there. Interestingly enough, I got a DNA kit to test her, but never did.

      1. Samantha

        The rescue agency I adopted my dog from said Shih Tzu too! I’ve also been told she could be part Maltese. The mystery for me lies in the fact that her fur never gets as long as either of those breeds.

        Maybe I’ll try one of those DNA kits!

        1. Hindy Pearson (Post author)

          Hi Samantha, First of all, so nice to hear you adopted your dog. There are so many dogs I’ve seen that are called Shih Tzus, but they all look different! Josephine’s fur never grew much either. I think there was a reason I was considering a DNA test, but I don’t recall now, or it might have been sheer curiosity. To be honest, I don’t much care what breed I get, as long as the dog needs a home, but I must admit, sometimes I’d just like to know. Red (the dog in most of my posts) is a Chihuahua/Min Pin (I say that because she looks exactly like a Min Pin, with the shortness of a Chihuahua). However, I’m convinced there’s Rhodesian Ridgeback in her, although my husband laughs. She has that stripe going down her back. In her case, I’m tempted.

  6. Virgil Williams

    Both my Shih Tzu’s have gone blind, the male has also suffered severe hearing loss. They are siblings that i got from rescue group in Oklahoma. The female went blind over a period of time and has adjusted very well. The male seems to have went blind over night and is having trouble adjusting. It is probably made worse due to the hearing loss.

    1. Hindy Pearson (Post author)

      Hi Virgil, first let me say how sorry I am to hear that, but how wonderful you chose to rescue. I understand what you’re saying about the boy having a hard time when it’s so sudden, and he’s having trouble hearing. We rescued a Shih Tzu that was deaf and could see shadows. In a split second, it seemed, what little sight she had disappeared and she literally cried for a week. It was heartbreaking to witness, but she did get through it eventually. What did the vet say? Is there anything you can do for him?

      1. Virgil Williams

        There is nothing that can be done. I carried my female, Fiona, to a pet Optomoligest in Tulsa, he said that Fiona had genetic retinitis and that there was nothing that could be done. My male, Rocko, probably has the same condition. Fiona has a small amount of far vision, Rocko is totally blind. They are 11 years old, so they should have a few more years. I will be here for them no matter what happens.

        1. Hindy Pearson (Post author)

          You’re all very lucky to have found each other.

  7. Brittany Coakley

    I am devastated about my teacup chiwahwah going blind from cataracts she turned 14 this yr but she’s gradually loozing her sight other then at a sudden moment I still send her to her bed at night right by me so I haven’t changed anything in that respect but still give her the same attention an love as I always have but o have to leAve her to go to work but she sleeps most of that time I’m away so am I doing the right thing by her by still treating her as always

    1. Hindy Pearson (Post author)

      Hi Brittany, I’m so sorry for what’s going on with your pup. Have you been to an eye specialist to see if anything can be done? Of course you should give her the same love and attention as before, just take care about things on the floor she can trip on. If you’ve seen this article you may have found others in my vision and hearing loss section that will help. Do you have anyone that can take your dog out when you’re at work? Can a friend or neighbour sit with her to keep her company?
