Yes I've used them in the past. Don't like the $$$ and the smell. Didn't like the smell with the salmon oil either (I used to use the kind you just pump on the food like handsoap). It wasn't too bad once eaten but if the dogs got wet they smelled fishy to me.
Nikon LOVES the coconut oil. He whines while I'm scooping it out. Coke likes it too but he's weird, if you are baking the one thing he wants to steal is the stick of margarine. He loves that greasy, oily stuff.
