"We just got a new shih tzu puppy, and I have been gradually switching her over to the Natural Ultramix from the other low quality food the breeder had the puppies on. At meal times, the bag doesnt even have to make a noise, and as soon as its opened the puppy can smell the food from the other side of the house and comes running into the kitchen searching for her bowl. She LOVES it! And I love it because its good for her. She previously had a problem with eating her poo when we got her, and since the transition of puppy food, she no longer has the disgusting poo eating habit either. I would very highly recommend this product."
