I love ALL these breeds, it's very hard to choose. I'd have to say that the siberian husky is my favourite, but if I had to choose one of these, I suppose I'd choose a bull terrier. They make good guard dogs, and have clownish personalities.

Since you said that you aren't getting any more small animals, another sibe wouldn't be any trouble at all. You are used to the breed, and know how to go about them. But Tikeya might not be able to handle another one of her lol.

Aussies ae very smart and nice. They'd make a great choice too.

And I don't know much about shar peis, but you gotta LOVE the wrinkles!!
