Overall the Tibetan Terrier is a healthy dog with few health problems associated with their stock. Yet, there are a few that need to be monitored for including their eye problems. The dogs can develop cataracts and in fact these are sometimes common in the dogs as they age. The cataracts that they have are often the same as you would see in a human cataract situation. Yet, for dogs that can not tell you what is wrong, it is up to the owner to pay close attention to these dogs and the quality of eyesight that they have. There are also several other types of eye conditions that can affect your Tibetan Terrier and that you can monitor them for. Nearly all dogs will develop some form of cataract as they age. While some development of cataracts is normal and to be expected, with the Tibetan Terrier, it can happen much earlier. These forms of cataracts can actually form on the eye of the dog as young as two years old. They are not associated with aging. Dogs that have parents that have this condition are most likely to have it. Therefore, if you are selecting your dog from a breeder, be sure that you know what symptoms and conditions of cataracts these dogs have had. It will be between you and your dog's vet to determine the right type of treatment for the cataract. Because the dog is so young, it may be necessary to remove them in an effort to protect the dog's overall sight in the long run. Yet, this decision is based on a case by case basis depending on the severity as well as the overall risks involved. Make sure that the dogs are seen by a vet regularly and that you have a canine ophthalmologist monitor the dog's condition. Often, you can see these cataracts once they are well into their development. They appear as a bluish white coating over the eye. In addition to cataracts, the Tibetan Terrier is also susceptible to other eye problems such as Progressive Retinal Atrophy. This condition is one which is much more detrimental to the dog's eyesight. The dog first loses his ability to see at night. Then, he will slowly begin to lose his eyesight until he is completely blind. This condition is another that is hereditary and therefore can be spotted in the heritage of the dog. There is no cure or treatment for this condition. By paying close attention to your dog's eye health, you can help him to overcome or at least get treatment for the condition. Careful monitoring of your dog's eye health and the way that he interacts and behaves is important in noticing potential problems.
