Millie has a cousin named Biscuit that some times spends spring break with us. Our old dog Tira thought Biscuit was quite annoying and hyper. But Millie is just about as hyper as Biscuit. So they play a lot. They fight over toys, make videos with us, etc. The only thing that Biscuit did wrong is teach Millie how to chew toys with great success in ripping them completely apart. Biscuit came from the Human Society and his name he had there was Batter. Dogs that come from the Humane Society are rescue dogs and I think he might have been rescued from a lake or some place wet because he's afraid of water. Biscuit is a very fast dog and it would probably hurt you and him if ran into you. At least no body has broken bones. Tira was as hyper as biscuit maybe even more hyper, and crashed into my Nai Nai and she broke one of her bones. I hope that Biscuit won't do anything like that. Millie isn't as fast as any of the two but she runs around the house when visitors come. Biscuit always is so happy to greet me when I see him! Good dog Biscuit!
