There are many reasons that affect the dog's appetite, but the main ones are as follows:

1. Feed First, dogs are reluctant to eat because the feed is single, stale, and has peculiar smell. The second is that the feed contains a large number of chemical seasonings, or substances with pungent smells such as aromatic and spicy taste, as well as particularly sweet or salty foods, which affect the dog's appetite.

2. The feeding place is not suitable such as strong light, noise, several dogs fighting for food, strangers present or other animals disturbing, etc.

3. Disease If the above reasons have been ruled out and the appetite still does not improve, the disease problem should be considered, and the dog should be observed for abnormal manifestations in various parts of the dog.
