Thanks, Wabbit. My current dog is scared of dogs larger than him, so I thought getting a smaller dog would increase the chances of them bonding. That's also why I would like a puppy. I guess if they grew up together, my first boy might not care how large the second one ended up... I know it's silly, but I feel bad he could lose his alpha position. He's so small, I want him to feel big somewhere. He's got a total Napoleon complex.
Is it true that the "teacups" are really unhealthy? Someone just told me my current dog would probably only live to nine years old!
