This's frozen raw lamb meat. Each time, my dog can only eat 2 pieces or she throws up if I feed her more. She's still hungry, eating, playing all the time but she just keeps throwing up and losing weight. Doc said nothing is wrong in her but it's a long journey of putting her back to eating right after years of eating bad commercial dog food. I really don't know what to do. I've tried evrything. I've spent all time, money, tears I have for my canine companion. It's like a marriage. We have my longest relationship.
