Dog diseases are just as serious as human diseases. They may be a little more problematic because they can't tell you where it hurts.
They can't tell us when something has changed, just as they can't tell us when they feel an improvement.
Most canine cancers and degenerative diseases are the same as in humans, whereas most of their infectious diseases are species-specific. As with other domestic animals, dogs are at risk from a number of infectious and genetic diseases, but most of these can be prevented through screening, vaccination and proper husbandry.
The first sign of deterioration in a dog's health is its behaviour. He will look depressed and withdrawn and move less than usual. His appetite may also change, sometimes improving and sometimes deteriorating. Generally speaking, a dog that is active, lively, interested, dehydrated, eating, drinking, defecating and urinating normally, free of lumps and hair loss, and of normal body condition is probably healthy, but if the symptom appears, a medical examination should be carried out immediately, and every six months if there are no symptoms.
We try to describe as many of the dog diseases as we can to help owners keep their pets healthy!
