Collies are generally healthy, but like all breeds, they’re prone to certain health conditions. Not all Collies will get any or all of these diseases, but it’s important to be aware of them if you’re considering this breed.

​

If you’re buying a puppy, find a good breeder who will show you health clearances for both your puppy’s parents. Health clearances prove that a dog has been tested for and cleared of a particular condition.

 

Collie Eye Anomaly: This inherited condition can sometimes lead to blindness. The condition causes changes and abnormalities in the eye. These changes can include choroidal hypoplasia, an abnormal development of the choroid (an inner coat of the eyeball); coloboma, a defect in the optic disc; staphyloma, a thinning of the sclera (the white outer coat of the eyeball); and retinal detachment. Collie eye anomaly usually occurs by the time the dog is two years old. There is no treatment for the condition.

Progressive Retinal atrophy (PRA): This is a family of eye diseases that involves the gradual deterioration of the retina. Early in the disease, dogs become night-blind. As the disease progresses, they also lose their daytime vision. Many dogs adapt well to limited or complete vision loss, as long as their surroundings remain the same.

​

Hip Dysplasia: This is an abnormal formation of the hip socket that can cause pain and lameness. Dogs with hip dysplasia should not be bred. If you’re buying a puppy, ask the breeder for proof that the parents have been tested for hip dysplasia and are free of problems.

​

Allergies: Quite common is dogs, there are three main types of allergies: food allergies, which are treated by eliminating certain foods from the dog’s diet; contact allergies, which are caused by a reaction to a topical substance such as bedding, flea powders, dog shampoos, and other chemicals; and inhalant allergies, which are caused by airborne allergens such as pollen, dust, and mildew. Treatment varies according to the cause and may include dietary restrictions, medications, and environmental changes.

Drug Sensitivity: The Collie is known to react to such drugs as ivermectin (found in heartworm control medication), anesthesia, and insecticides. Consult with your veterinarian before giving your Collie any medication or using flea or tick control products.
