If you do not overfeed, then dogs do not gain weight. Apparently the food is "lightweight". We have been feeding dogs with this food for many years. The quality varies, but there were no problems with the animals.
Has pros:
They eat well, for all breeds and sizes, normal stools, not puffy.
With its cons:
The package does not seal properly after opening. In different packages, the food differs in appearance, density of granules, fat content.See full review
