There are many, many good dog foods on the market. Surely, one will satisfy both your pocketbook and your dog's palate. Overeaters Many breeds of dogs are notorious for their propensity to eat beyond satiation, beyond what is nutritionally required, and may even eat themselves to death. These tend to be the domesticated breeds such as beagles. The more primitive breeds such as the northern breeds or breeds recently off the African plains, such as Basenji's, tend to eat when they are hungry, and not to eat when they are full.
Obesity is the most commonly noted medical condition.
Simply stated, we let our dogs eat too much. It's not just weight that is the issue, but overeating can cause stomachs to rupture or to predispose the dog to bloat. The solution lies in restricting access to food other than food given at mealtimes. Another cause of obesity is the extreme palatability of today's dog rations. Some medications also increase appetite.
