Hi everyone, a couple months ago, i purchased a "Dinosaur Birchir" from PetSmart, it was really small, about 1-2" I noticed he wasn't growing fast, or at a normal rate as normal Birchirs do, and i did research and found out he's a Short Body, i was kids bummed out, but i still kept caring for him, he's about 4-5" now, and is pretty thick, i was just wondering if anyone could tell me how big i should expect him to grow and in how long? Any info helps, Thanks!
