I use sardines regularly as one of the proteins that we mix with Dr. Harveys premix. The girls all love the sardines. I use the kind packed in olive oil and do not add extra oil on the days we use sardines as our protein.
Yes, I give mine all mine sardines in small quantities. I was at a grooming seminar and the guy was a professional handler,too. He always gives the dogs sardines to improve their coats. He said any of them are OK as long as they're not in the hot sauce:w00t:
Mine don't like them mixed in their food- they like to eat them by themselves.
My dogs and cats get a meal of Sardines once a week without fail. I use the kind packed in water with no salt and stock up when they go on sale. I just give them as many sardines as it takes to equal their normal food amount.
