And individual dogs of any breed aren't really representative of it's respective breed. I will use our last dog as an example, a miniature poodle. Including the one we had, I know of four ore in the family. They are all different from each other. One is a yapper, one is really laid back, one is friendly with everyone, and ours was a rescue and had a bad puppy life and was timid, especially with respect to men, loves some children and didn't like others, and was partial to older women. The yapper seems more comfortable with men and small children than the other three. The laid back was a puppy mill rescue and can't jump. She can also get protective with her toys around other dogs. The friendly one doesn't really like other dogs, but will tolerate them. Ours tried to baby every dog that was around her. As you can see, there is a great variety among each breed. The individual dog, no matter what the breed is what you must look at.
I also don't agree with Tom about cats being the best dog, but I'm a dog person, not a cat person. Cats do need a lot of care, depending on the cat, and some cats do bite. They will also often claw furniture, walls, etc., even when provided a scratching post or pad. If they are kept inside, one has the hassle of taking care of a litter box. I'd rather walk the dog and pick up after it.
