If he is suffering from vision loss, your dog may stay in one place for several minutes or even hours. Because he sees less, he stays where he feels safe. Most often, it can be their basket or cushion.

4 – Your dog is not asking for a walk

A dog with weakened vision appreciates walking less. He does not claim them and above all, if you untie his leash, he will not run. He remains next to you again and again. He seeks your presence so as not to get lost. You are his landmark!

5 – Your dog is no longer playing

Your dog may play less. There is no lack of desire, but your animal hardly sees his toys anymore. He lacks responsiveness and realizes his limits.

6 – your dog jumps when you pet him

This sign is undoubtedly the most revealing: when you pet your dog, he jumps. This reaction is simply due to the fact that he has not seen you. Reassure him and for the next few times, try to be louder so he knows you’re there!

Causes of vision loss in dogs

Vision loss related to an incident

There are many causes of vision loss in a dog. This can be caused by an incident. It is possible that your pet has injured himself, but in this case, more often than not, only one eye is affected. It is also possible that your dog received a harmful product in the eyes. Good rinsing and veterinary control are essential.


Cataract is a pathology that affects people and animals. It is caused by aging. Dogs are no exception. Cataracts occur around the age of 7. The disease is recognizable because the lens of a whitish veil. of the dog is confused. Before the appearance of the veil, blue reflections can be seen. Over the months, the dog loses its visual abilities. The signs do not deceive, they are those mentioned above.

If you are concerned about a cataract, it is essential to take your dog to the vet. Although the disease is inevitable, it can be slowed down with drug treatment. If it is early, it is possible to operate on the dog. But if your pet is elderly, the anesthesia would be too dangerous.


Glaucoma is another eye disease that affects our pets. This ocular pathology leads to a gradual loss of sight. Glaucoma is the cause of increased pressure in the eye and degeneration of the optic nerve and retina. Glaucoma can have several origins: inflammation (uveitis), dislocation of the lens or malformation. It is painful and must imperatively give rise to a visit to the veterinarian.

Retinal detachment

Retinal detachment can affect the dog. Know that in humans, this disease is hereditary. In dogs, certain breeds have predispositions. This is the case with the Collie. Retinal detachment can also be caused by a wound or high blood pressure. If the retina detaches, the affected eye no longer works. The pathology can be cured if it is taken care of early.

Progressive retinal atrophy

Like retinal detachment, progressive retinal atrophy is an inherited condition. The breeds that have predispositions are Cockers, Terriers and Poodles. Progressive retinal atrophy first reduces night vision and then gradually leads to blindness.

The eye tumor

Whether cancerous or not, the tumor can be the cause of vision loss in dogs, especially if it is an eye tumor. Depending on its size and location, it may be supported.

If you notice that your dog sees less well, you should make an appointment with your veterinarian to identify the source of the problem. If the vision loss can be treated, slowed down or stopped, treatment will be offered.
