I have decided to go ahead and get my new Sheltie puppy Friday. I had always fed my previous Shelties Wellness Core and it did really well for Missy. I like the Wellness product and had planned on feeding the new puppy Wellness Puppy Formula. However, the breeder sent me a message that she only feds frozen food, firmly believes it is the way if you want a healthy dog, and would send me home a bag to get started. She said she would explain her philosophy about food to me Friday. I don't know a thing about frozen food and will wait to hear what she tells me about it, but was wondering what some of you feed your Shelties?
