Thanks for all of the nice replies! =)

Fozzie is being a very good boy, and he's very happy... all the time! He almost weighs 10 lbs now! His vet said that the weight of a dog at 12 weeks multiplied by 2 (plus a few lbs) is the adult weight. So, he should be under 30 as far as we're estimating. I do hope he stays small, he's just too cute and cuddly.

He had fun again at Flyball practice this morning. However, Gonzo didn't have so much fun! A Golden Retriever in training was doing recalls alongside Gonzo, and he went after Gonzo. Neither of them got hurt, but I could tell Gonzo was freaked out. After that, he didn't want to run for the rest of the time >;[... I hope that doesn't affect him. He was JUST starting to focus on only me and he hasn't chased a dog for sooo long. Ahh, well...
