My brother, his girlfriend, and his puppy came home yesterday at 2:00 a.m. Of course, McGregor started barking, so we had to let him out, and let the two dogs get acquainted. Finn, my brother's dog, is a golden retriever puppy. He's very sweet, but much bigger than McGregor. At first McGregor didn't know what to think of Finn, and was a bit scared. Then he bit him. Then Finn humped McGregor, which pissed McG off. They've worked things out, and currently spend a lot of time chasing each other around. However, our house is now rather chaotic.
