Is The Miniature Australian Shepherd A Naturally Thin Breed?

(PA)

Hello, I have a 9.5 month old Mini who is a neutered male. I've been a bit concerned about his weight, and am wondering if Aussies are naturally on the thinner side as far as body score condition. My vet has given him a clean bill of health, and rated him with a body score of 3.5 under all of his coat, so yes a little on the thin side.

He has a very sensitive digestive system, and so during the last 6 months we have battled several lengthy bouts of diarrhea (consulted our vet each time). After 3 food changes, including a Royal Canin prescription diet, I've finally stabilized his GI tract with Wellness Puppy Complete Health.

I allow him to eat however much he wants, and have even come to the point of bribing him to eat by mixing in a tiny bit of peanut butter with his food. He's a typical Aussie—always on the go and full of energy even after a good amount of exercise each day for his age—so I'm not sure if this is normal for the breed or if I need to go to other measures to put weight on him.

Any advice would be greatly appreciated! Thank you!
