There are a variety of different diseases that can afflict dogs. Some of these diseases are exclusive to canine species, while others can affect other animals and humans as well. Some dog diseases are infectious, such as parasitic infections, viruses and bacterial infections, and some are inherited or related to the breed, such as hip dysplasia. On the other hand, some are spontaneously developed like many cancers and nervous system diseases.
