There are many reasons that affect a dog’s appetite, but the main ones are the following three points:

1. In terms of feed: First, dogs are reluctant to eat because the feed is single, stale, smelly, etc. Second, the feed contains a large amount of chemical condiments, aromatic, spicy and other pungent smelling substances, as well as particularly sweet or salty foods, which all affect the dog's appetite.

2. The feeding place is inappropriate, such as strong light, noise, several dogs competing for food together, the presence of strangers or interference from other animals, etc.

3. Disease: If the above reasons have been eliminated but the appetite still does not improve, disease should be considered, and attention should be paid to observing all parts of the dog's body for abnormal performance. If any problems are found, please consult a veterinarian in time.
