We have a chocolate lab who started to lose all her hair after we switched to a dog food that was a “premium” food. We took her to the vet who prescribed a oatmeal and kangaroo food and gave her some meds. Her hair didn’t grow back. After some online research I choose to go with Natural Balance Dog Food ( http://www.naturalbalanceinc.com/) Our dog is now 4 years old now it took some time but she has her hair back and overall is doing better. I would highly recommend the dog food. She still does have flaky skin which I haven’t been able to solve but overall she did so much better once we switched her over and I can’t see us ever switching again.
