Hi,
Peanut was, as I have said in other threads (sorry readers !), getting bored with her kibble only food very quickly. She refused to eat nearly anything sometimes, and at 11/12 ish weeks it was quite worrying. We read up about barf and decided to go down that roue the next day.
Well, different dog doesn't come close to the way she walloped off her food from the first feed on barf. She still has a small amount of kibble mixed in, but that is because we had bought in bulk before Peanut arrived :'(.
Personally I would give your dog the change quite quickly, not necessarily all change in one go but quick as they absolutely love it. Tripe is a particular favourite but not with the wife ;D who sprays air freshener after it !!
At 16 weeks Peanut knows at the end of a walk she is going to be fed and pulls on the lead to get back asap, runs to the kitchen and barks for her meal, no better write up for barf in my opinion!
Regards,
Graham
