The main reason why a dog refuses food is that it is not hungry.

Some dogs will eat anything and are quite happy to devour what's put in front of them, but some will show a reluctance to eat or simply turn up their noses and refuse certain foods. This can sometimes be a sign of intolerance to certain ingredients or they may find the food difficult to digest. Dogs can also develop aversions to particular foods as they get older. Pero Gold may be the answer if your dog shows any of these signs.
