Among the many inherited conditions that can affect your dog's eyes are a group known as corneal dystrophies. These conditions cause abnormal corneal development, usually in both eyes, and lead to various problems with the animal's vision. Depending upon the type, one or more layers of the cornea (the transparent lens that covers the front of the eye) will be affected. The major types of corneal dystrophies are:
Epithelial Dystrophy, which causes shallow but painful ulcers and erosion on the surface of the cornea.
Endothelial Dystrophy, which affects the function of the endothelial cells, causing a buildup of fluid in the cornea (also known as corneal edema). [...]
You may have noticed that your dog or puppy appears to have a metallic or opaque look to the outer layer of each eye, either in the middle or to the edges of the eye. In some breeds it may also appear like a crystalline growth in the eyes, or even as a smoky or smudgy area of the cornea. Any type of eye discoloration that is inherited, bilateral (affecting both eyes), and is not swollen or inflamed is known as corneal dystrophy. This condition is common in many different breeds of dogs and can strike at any age from just a few months old up to senior ages. Typically the condition affecting the dog's vision will slowly progress, decreasing sight in both eyes as the dog matures and ages. In some breeds the progression will be relatively slow while in others the condition rapidly leads to vision loss. [...]
As with many Brachycephalic (short-nosed) breeds with prominent eyes, the Boston Terrier unfortunately suffers from a number of eye problems. Some are less severe than others, though all require prompt veterinary attention. If you are considering the addition of a Boston Terrier to your family, you must be willing to devote time to regularly checking the health of your dog's eyes and bringing him or her for regular visits to the vet. Some of the more common eye conditions that can develop in Boston Terriers are cataracts and corneal ulcers, the latter usually in conjunction with corneal dystrophy. [...]
Most puppies have worms when they are born, that they contracted from their mother. Fleas and worms are another health concern that can cause a variety of problems. New puppy owners have to deal with this as both part of their puppy's care and the duration of their dogs' life. Worms are nasty parasites that usually live in a puppy's digestive system, but some do invade the heart or other organs. Puppies experience problems ranging from anemia and vomiting or, in the case of heartworm, even death if left untreated. After a veterinarian identifies the problem, treatment is normally very effective and straightforward. [...]
