well i just wanted to say last week i switched shelly from primal to stella & chewy's and it has been amazing! she was very skinny and i had problems getting her to gain weight on primal. i was feeding her 3x the amount she needed and seeing NO results. the owner of the store i buy my food at told me it could be because i had the turkey and sardine flavor and that is low in fat, and then recommended i try stella & chewy's because it has a higher fat content. i am feeding shelly double what she needs right now, along with a tbsp of wet food and in just 2 days i noticed a difference! she no longer looks like a stack of bones! i am so pleased! also her coat has gotten softer from stella and chewy's and her eyes tear less. i really liked primal and their selection of flavors, however i guess stella &chewys just works better for my chi!
