He he.. like others have said, you don't! I'm pretty sure I'll always have at least two dogs.

I agree with Shelteez2, though. If you do decide to bring another one in, I'd wait until Bijou is full grown and well trained. Dealing with two puppies can be pretty tiring and hectic.

How's Bijou's puppy stage going? He's a cutie! I've found that Collies generally have a more "mellow" stage then most breeds.
