I have a gorgeous Dalmation, who may be mixed with Lab, but we're not sure. His name is Pete and he is 3 years old. I have been toying with the idea for a while of getting a companion for him. He is a happy dog, very sweet, mellow, but at the same time he loves other dogs especially puppies. And I love dogs, and feel another dog would be fun for him and me! But, I want the right dog. Pete is 88 pounds and I'm thinking I want a medium dog, like 40-50 lbs. SO, my questions - are two dogs a ton more work than one? Will the puppy learn more or less quickly to be socially graceful with Pete in his life? Will Pete like the new puppy for a week and then get bored? I have many more questions, but I guess I'll stop there for now. Also, I love the Australian Shepard- does anyone know anything about their basic demeanor?

Thanks!!
