It is interesting to see that others have had trouble with Wellness food.
I felt that it was probably time to switch to adult food...so I went to buy adult kibble to mix with the puppy kibble and gradually start the process. One of the Pet Smart people recommended Wellness and I bought into the "natural product" stuff. The guy I talked to didn't think much of the prouduct I was using.
All well and good, but the Wellness food did not agree with Copper even though I was introducing small portions mixed in. I took the bag back and bought the adult brand of the kibble (Royal Canine)I was using. We are still doing the mix...no problems. Copper likes it, is healthy and energetic...so good or bad, we are sticking with what we started with.
