Single Eye Dilation

by Mary
(Renton, Wa, USA)



Anyone ideas as to why my puppies eye will dilate like the picture shown? It doesn't seem to occur with any kind of regularity or cause. He's 18 weeks and this has happened 5 times since we've had him. It usually resolves on its own after an hour or so.

Any information would be most appreciated!

Anisocoria in Dogs
by: jcrply

If you will GOOGLE the phrase "Anisocoria in Dogs", you will find lots of information about it and lots of photographs. There are serious causes and not-so-serious causes of this condition. I hope your pup's is one of the not-so-serious!

Intermittent Anisocoria
by: Tara

Hello, we have a 5 month old blue merle, blue eyed boy who also has had one pupil shrink 3x in the last month. The pupil that shrinks is not always the same eye. It too resolves within ~1hr. Any other insights as to what might cause this? Did you follow up with any specific medical procedures? We have a vet appt to address this in a few days.

Rudy is almost 3 years now and he hasn't had an incident in a long time. He seems to be normal with all of the personality traits of any other Aussie that I've read about. He's an awesome companion and my 4 legged fur baby. :-)

My vet recommended a "wait and see" policy to see if it happened on a regular basis or got worse. He told me that this is sometimes something that can happen and they can grow out of it.

Luckily, thats what happened with him so we didn't do any medical procedures. It always happened with the same eye so we will still watch for it. He is 3 years old now and it didn't seem to have any lasting effect.

Hope it is the same case for you and your pup!
