Like with basically every other ailment, knowing how to tell if your dog is blind my not be that easy. And the reason is that dogs are really good at feigning fine even when they are going through it.
So, while you might expect your dog to start bumping into things and such because he is losing his sight, that will probably not happen.
You will need to adopt a more hands-on approach to detect any funny business. And for that, this article has got you covered.
Check His Eyes
By this we mean you should actually get your dog and look into his eyes. Check for specs or dirt or debris.
Some of those things might not be indicative of blindness but they are definitely things you want to check out.
Be sure that you are doing this check in a well lit place so that you do not leave some things out or mistake one thing for another.
Also, make sure that your dog is not anxious or anything because you will be prying his eyelids apart and that in itself could be uncomfortable.
So, be sure that they are calm and you could also make their favorite treat and/or toys available.
Some of the things you might notice from looking into your dog’s eyes are different sized pupils, crustiness and teariness of the eyeballs and maybe even cloudiness.
Now, whichever of those things you notice require immediate medical attention. It doesn’t mean that something is wrong, it is just better safe than sorry.
That said, cloudy spots in your dog’s eyes is probably glaucoma. And unlike the other things we just mentioned, glaucoma could eventually lead to blindness.
The Menace Test
Well. aside actually prying your dog’s eyes open, the menace test or threat test is a pretty popular test for finding out if your dog is losing his vision.
So, this test works based on a dog’s (or even human’s) instinct to blink once he notices something coming too close to his face.
First off, to get a really accurate result, make sure that you do the test one eye at a time. So, close one eye while you test the other.
With that sorted out, move your palm ever so slowly close to the open eye. Going too quickly will introduce air pressure that will make your dog immediately figure out what is going on.
Also, be careful not to touch his whiskers because that would also alert him. So, if you do this and your dog doesn’t blink, report that to your dog’s vet immediately. Remember to test both eyes, though.
Now, remember that we mentioned that your dog is probably not going to be bumping into stuff.
Well, this is partly due to the fact that they have already mastered the layout of your home.
So, if you suspect that your dog is going blind, you could try to rearrange the furniture in your living room or something.
When that is done, call out to your dog once and see how he fairs. Be sure not to consistently call out to him because he could trace you by the sound of your voice.
You want to be sure that all your dog has to locate you is his eyes. And if he keeps bumping into furniture, he is probably losing his vision and should be immediately taken to the vet.
This test works based on your dog’s instinct to follow with his eyes the direction of stuff that they are interested in.
Now, because your dog’s other senses are probably in really good form, be sure to pick an item that is really light and makes no sound even when it is dropped. For this, people usually use a cotton ball.
So, right there in front of your dog’s face, drop a cotton ball down. Under normal circumstances, your dog’s eyes should follow the path of the falling ball and/or look for it on the floor.
If this doesn’t happen, you’ll need to take your dog to your vet to find out what’s up.
Bumping Into Stuff
Yea, we know that we said your dog might not bump into furniture and stuff but some dogs might.
If a dog has begun to show signs of weakness, it usually shows that things have gotten to the point where they can no longer bear it. However, some dogs will not just try in the first place.
Whatever the case, though, bumping into furniture and stuff is definitely a sign that you should talk to your vet.
That said, you do not have to wait till your dog starts to seem like there is something wrong.
You could make some of these things a routine check thing, just like you go for routine eye checkup. Remember that a stitch in time saves nine.
