It is interesting to see what everyone is feeding their dogs. I have tried Innova EVO, Nature's Variety Prairie and Freeze-Dried Raw, Solid Gold, Merrick, BilJack, plus maybe a few others I've forgotten. The only one of these that she ate at all was BilJack. (I know I gave in too soon and she probably would have eaten them if I'd have forced the issue, but I guess I was a mush -- I gave all of them to my neighbor who has 2 small dogs and she was thrilled. Apparently her two little girls will eat anything. But she did report that they liked the Merrick (I think it was turducken or stew) the best.)
The only brand Daisy will eat reliably is the one she came home with from the breeder -- Purina Pro Plan Natural Selects Turkey and Barley. It's not the grocery store variety of Purina. It's only available in pet stores.
The vet said Daisy needs to lose 5 pounds (), so I found the above post about feeding foods with no grains to be interesting. The Pro Plan Natural Selects is very good given all the standard ingredient evaluation criteria, but of course it does have barley, so maybe I will try a switcheroo again. But I know it will take lots of determination because she does not take well to any food other than her normal. I'm sure she will go on a hunger strike for a few days.
I've read the RC ingredients many times in the store, and there is always at least one thing in the ingredient list that makes me put it back down. I don't remember right now what it is (I think it was a significant grain content, but I'm not sure). I'll have to look at it again. From what I've read on this board, it has that kind of oily coating that Daisy's current food has, so maybe she would accept it. Although this isn't an issue with Cavaliers, I talked to a Maltese owner and she said her breeder told her not to feed any food with beet pulp to her dog because it causes the red/dark staining you see on many white dogs' mouths/chins. I know RC has that, and it's listed pretty high.
