This. People are always asking me if 4-year-old (Am. Staff.) Jack is a pup, and how big will he be when he's full grown?
He's a little ribsy, and he always has been. But remember that the average dog owned by your average dog owner is overweight, being free-fed and over-treated.
Jack, "obviously" in desperate need of a good meal:
He's beautiful! He looks like he could be a littermate to my brothers dog, Sid!
