I was wondering out of curiosity what do you feed your dogs?
I currently feed Tank, Charlotte and Kaia Fromm Four Star Grain Free Game Bird recipe. They also get fish oil and glucosamine everyday and Vitamin E every other day.
Charlotte and Kaia have been on Fromm Four Star for a year now and they are looking wonderful and doing great on it! I am so glad I finally found a food that agrees with Charlotte's stomach and does not make her loose her fur and have dry, flaky skin.

. She doesn't have any allergies or medical problems tho, so not sure if this helps any.
