Single diet

Many owners like to feed their dogs one kind of dog food. If the dog only eats dog food for a long time, it will cause nutritional imbalance and easily develop the bad habit of being picky and anorexic. Dogs are omnivorous animals, so they need to pay attention to the diversity of their diet. Whole grains, meat, vegetables, etc. must be fed to dogs appropriately.

Influence of parasites

Dogs are susceptible to intestinal parasites, such as roundworms, tapeworms, nematodes, etc., which live in the intestines of dogs In the tract, it absorbs nutrients from the body to maintain its own growth. It causes the dog to be thin, so the dog will not gain weight no matter how much he eats. Puppies must be dewormed every quarter, and adult dogs must be dewormed once every six months to ensure their health.

Gastrointestinal problems

Dogs usually have a good appetite and eat a lot, but they do not gain weight because the food is not well digested and absorbed. If your intestines and stomach cannot absorb it well, you will naturally not gain weight.
