I had Riley on Merrick turducken (actually I was trying to transistion her to it) and as I added more, she wanted it less and eventually threw up. After a trip to the vet, he put her on low reside for two weeks to let her digestive track "rest" and then wants her on Royal Canin Medium Breed. These past two weeks I have put yogurt with her kibble as well as a little shredded cheese and she has eaten like a champ. Down side of the low residue is that it has a BAD preservative listed at the very end...At any rate, I have been looking at dog foods yet again and my vet's big thing is that they HAVE to had had food trials...that is why is looks at the major brands. I did check on CSDS and it has trials, it is rated 4 stars but, on the rate it all site, there are some who really trash it and others who swear by it. It is higher rated than the Royal Canin and I hate giving her corn gluten, I don't want her to throw up or have diahrrea, so....Can any one give me their experience with this food?
