I feel that each dog may react differently to different food / treat. I've heard of dogs who are on super premium food that is suppose to build up mass but still remain as skinny as ever.

I also got 3 cats at home eating the same kibbles but one of them got serious UTI. Inpatient for 3 days!!!

I do give my boy greenies but not often, mayB once a fortnight. He chew on more dangerous things before (his rubber ball toy)

Anyways, this is just my 2 cents worth. Everything in moderation.

I make my own treats for my animals so I rarely give them commercial treats. Even if so, very small quantity...
