Definitely have fun. If you have a bigger class dont be afraid to play with him. He is just a baby so the more fun you make this experience the more he will enjoy it as an adult.
As a young pup, my little one spent many a conformation class walking around with a squeaky mouse in his mouth--as proud of his "kill" as could be!
There is NOTHING more irresistible than a Yorkie puppy playing! |
