Gizmo loves those wellness puppy treats too! When Gizmo was 16 weeks he was only 2lbs. Sounds like your yorkie is going to be a good size! I would say between 4-5 pounds full grown
Gizmo is only 3.5 pounds and he is 10 months old. I hope he grows a bit, he is so fragile!
Good luck trainning your furbaby!!!!
