We adopted a 1 year old male GSD a month ago, 11/24. He had been a stray picked up by animal control and was reportedly severely emaciated when picked up in Sept. Animal control turned him over to a private rescue shortly after receiving him since they didn't have resources to rehab him. We adopted him from the private rescue, and he was still underweight when we got him, but no longer emaciated Our vet says he seems healthy except for needing to put on weight. I've no experience with this kind of medical problem. We're feeding him as directed by our vet, but I'm worried that he's not putting weight on fast enough. We took him for a weigh in a week ago and he was 71 lbs. I can still see his ribs, although he has filled in a little there in the last month. He seems to get tired fairly easily too. Anyone have experience with this? How long should it take to get to a normal weight? Is the stamina issue related to his having been emaciated or could there be another underlying medical issue? Just worried about his health.
