This boy came home from the rescue this week. He's a young adult, unsure of precise age, perhaps 2. He's been underfed and underexercised his whole life, probably a would-be stud dog kept in a shed or something. Vet said he's basically healthy, but underweight and lacking muscle. The shelter had him on Harringtons kibble, which he likes well enough, but he's so hyperactive and zoomy I don't think he's going to gain much weight.
