I feed Nature's Variety Instinct Salmon Meal Formula. I like it but Cherry has gained a lot of weight on it. She's up to 58 lbs now, ugh. On Wellness with regular exercise she weighed 45-50. Started a cut back today. It is lower protein than the Wellness Core she was eating as well and I think that has contributed to her losing some muscle tone. But, I'm hoping her next blood panel will show her kidney/liver levels went down since feeding it.
Overall, I think it has helped a little with Cherry's allergies. But then again, hers are mostly environmental. As long as she's eating a limited ingredient diet that is salmon based, she does well on the food. She has had a lot less yeast problems in the ears though, so that is a plus!! Potato feeds yeast, another plus of a potato free food.
