Glens are generally healthy, but like all breeds, they're prone to certain health conditions. Not all Glens 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. In Glens, you should expect to see health clearances from the Orthopedic Foundation for Animals (OFA) for hip dysplasia (with a score of fair or better), elbow dysplasia, hypothyroidism, and von Willebrand's disease; from Auburn University for thrombopathia; and from the Canine Eye Registry Foundation (CERF) certifying that eyes are normal. You can confirm health clearances by checking the OFA web site (offa.org).

Glens are also prone to progressive retinal atrophy (PRA), a degenerative eye disorder involving the loss of photoreceptors at the back of the eye. It causes a gradual loss of vision and eventual blindness. Vets can detect PRA years before the dog shows any signs of blindness. If you're buying a puppy, look for a reputable breeder who has her dogs' eyes tested and certified on a yearly basis.
