Hello again. Here’s a bit of background on my Doberman. I have struggled with keeping weight on him since he was a puppy. He is active in dog daycare 5x a week (comes to work with me, too much separation anxiety to leave at home). I have tested him for everything and tested him again. He is 5 years old now and is like 60-65lbs. I have tried pro plan sport, diamond extreme athlete, Victor high energy. He was just at the vet two weeks ago to do another $400 GI Panel. Every test has come back normal. I just put him on Dr. Tim’s momentum. The vet wants to see how he does on it but ultimately wants to try him on a royal canin gastric food. I’m okay with that but honestly am not convinced he will gain weight on it. He’s eating 4 cups a day, because anytime I give him more than 4.5 cups he ends up with very loose stool-diarrhea. I have tried satin balls and he did gain weight on it. This time around it doesn’t seem to be working as well but it’s also not practical long term. It seems that anytime I stop adding satin balls he drops the weight. Has anyone had luck with putting on weight and maintaining it? I’ve tried raw with him as well. I’m at a complete loss and I’m feeling defeated. He needs to be at 70-75lbs as that’s when he looks his best and healthy. Open to suggestions, while I work with the vet. I have also gone to 4 different vets about this. One thought it was anxiety related and another thinks it’s nutrition based. You can see his ribs, hips, he looks horrible and I feel like a horrible owner because I can’t figure it out and help him. He is a great eater, not picky. Please help with nutrition suggestions, maybe tests my vet hasn’t thought of, anything.
