Why is my dog alert but has no appetite?

If a dog is in good spirits but has no appetite, it may have eaten something hard to digest, causing indigestion, or it may simply be picky.

The owner can give pet probiotics to promote intestinal movement; once the food is fully digested, the dog will gradually regain appetite. Normally give fewer snacks, since frequent treats easily create picky-eating habits.

In addition, a dog in heat may also lose appetite; observe to judge. There are many reasons a dog stops eating, so if it lasts a long time, take it to the clinic for a check-up.
