Hey everyone! I know this question has been asked multiple times before but I need more updated info and help! I got my Mando who’s an almost 19 week gsd puppy 2 months ago from a possibly sketch breeder. So far he’s extremely energetic and loves to play but he cannot seem to gain weight no matter what I do. Most recent vet visit showed that he was barely 26 pounds and is 18.5 weeks at the time! We have been feeding him royal canin German shepherd puppy breed food for the last 6 weeks, 3 cups a day and just recently increased to one can of blue wilderness puppy can food and 2 cups of Rc gsd puppy dry food to now make it 4 meals a day to try to increase weight. I don’t think he’s particular very active other than typical puppy play, I walk him around my street once a day and that’s about it. He runs behind my cats at home and does basic training as well. Tested him for worms twice and have had monthly dewormer and all his vaccines. At one point I wondered whether he was actually a mix because I thought his hips and hind legs looked like a hound and unfortunately we did not Do much research before getting him (we really needed to get him at the time we got him due to our work hours and I couldn’t wait 6 months on a waiting list at more expensive/reputable breeders) and only got a couple papers from the breeder but our vet believes that he is a true shepherd. if anyone had any Ideas on better food regimen to help gain weight or if we should be on the lookout for other issues he may have that could be causing lack of Weight gain. He does stool at least twice a day, with this new food regimen and I haven’t seen any worms. Appreciate the help!
