Our Charlie is almost 20lbs, but he wears it well.
Our little girl Coco is twice his age, and half his size, lol.
Jinx weight suits his large body. Unfortunately, he’s a bully. Tessa is only 8 pounds but doesn’t take his crap. She backs him up and makes him scream, lol. We call her “the little panther” as she’s also black.
