Hi, and welcome back. Henry sure is cute. It's okay if he's small, maybe his mom was a smaller bully. My two guys are 16 months old now, and they both weigh 45 pounds, they won't be getting any bigger, and as a matter of fact, our vet wants us to keep them around 40 lbs. Bulldozer and Blossoms mom was a smaller bully too. It just makes them super cute.
