I was giving my dogs Science Diet Puppy food from the time I got them at 8 weeks. Science Diet changed the formula about 3 months ago and the food just did not smell or look right. It was very oily and fishy smelling, which I realize they did at more fish oil. After about three weeks of the new food, I noticed my puppies (well now 1 year olds) skin was very flaky like dandruff and they both had been continuous licking their paws. I took them to the vet and he said they had food allergies. He wanted me to take them off the Science diet and put them on pumpkin and pinto beans for 7 weeks. Well, under duress I tried it and my dogs did not eat for 3 days. I decided to try the Newman's organic and after about 4 weeks their coat looks so much better and the licking has really decreased. I am so glad I saw this food when I was doing research.
Output:
Positive
