No weight gain for border collie...
I have a blue merle border collie he is beautiful and smart and full of life. With the exception of he will not gain weight, I am banging my head against a wall. I have tried puppy food, wet food, natural balance, chicken, beef, mixing food with dog food. I have been to 2 vets with no answer or than neutering. Which its not like I am not going to but I know that that will not be the complete answer. I am looking for some help, I have had one other person metion calf milk, like a protein drink?? To top it off he has tummy troubles diarrhea and vomiting for unmknown reasons... I am asking for any help?!
