Cataracts In Dogs

Most cataracts in dogs are the result of a genetic or hereditary defect. Many dog breeds are predisposed to hereditary cataracts, which may occur as early as at birth or develop later in young or middle-aged dogs.


A cataract is an abnormal cloudiness of the eye, caused by a change in the lens. 


Head Vet, Sean McCormack, of dog food company explains: ‘Cataracts stop light reaching the back of the eye, reduce vision and eventually cause blindness. The most common causes of cataracts are due to old age, diabetes and eye disease.’


He continues ‘Cataracts are slow growing, so you may not notice them until later on but here are a few symptoms for you to be aware of:


  • A cloudiness, or grey tinge in your dog’s eye(s)

  • Loss of vision, especially in low light conditions - this can be very tricky to notice because it often develops slowly, and most dogs are very good at adapting by using their hearing and sense of smell instead.

  • Pain - cataracts aren’t painful, but some of the underlying conditions that cause them are (such as eye injury or glaucoma).’


‘Contact your vet if you notice any changes in your dog’s eyes, or if you think they are losing their vision.’


Ultimately you know your pooch best, if they are acting out of the ordinary and you are concerned it’s always best to contact your vet.
