My sheltie, Henry, is rather large and always has been. When he came to us at 5 months old, he was already 25 pounds and got up to 50 fully grown (he's 4 now). He's also very tall. I asked the vet about his weight and he said he was fine but shouldn't get any bigger. At that point we were giving him 1 cup of food per feeding, so I scaled it back to 3/4 per feeding. He got to 45 pounds which seemed healthier. Now he just seems hungry, as he's been greedy and scavenging around the kitchen. Does anyone else have a large sheltie, and how much do you feed them? If coat is any measure of thyroid health, he has a full, beautiful one. Thoughts? Am I underfeeding him? How do I feed him and keep him from getting too heavy? He doesn't look obese-- not even close. Just a big sheltie. I've never seen one so big! PS- He gets fruits or veggies for treats, in his bowl, after he's finished his food. Anything else, and he becomes such a beggar!
