Sounds like Ozzy had a nice start for his first time!
Oh, I just wanted to warn you. Be carful with Oz when you bring him to the dog park. He is still a puppy (7 weeks?) and our dog parks won't allow any dog in until it's over 4 months of age. Reason being, there are diseases that small puppies could contract. (ex: parvo)

Not trying to scare you though! Congrats again on gorgeous Ozzy boy!
