The Science behind Man’s Best Friend
As a dog owner or lover, the welfare of dogs will be important to you; but did you know that many diseases in our canine companions are the result of over 10,000 years of domestication? During this process, we humans have selectively bred from certain animals for various aspects of size, performance, behaviour or appearance resulting in over 400 breeds. Unfortunately, in some cases, this selection has led to breed-specific health issues.
Many genetic diseases occur in dogs and other companion animals. Some of these are due to random mutations that became established in some breeds, examples include an increased risk of cancer and organ failure. In other cases, diseases can be a direct consequence of the features being selected. For example, breathing difficulties occur in some breeds because of selection for a short muzzled head shape while skin infections can occur as a result of excess, deeply folded skin.
Efforts by responsible breeders, veterinarians and geneticists to try to tackle some of these diseases are gathering momentum, but a team approach is needed and owners and prospective owners have a very important role to play in helping to eradicate them.
