The breeds that I would not want to own are breeds that don't mix well with my lifestile, I love the temperment and look of the huntingdogs, but I don't hunt. Hounds don't appeal to me neither do terriers. I want dogs that are smart and like to be with you and learn, train and work. Also I would not go out and buy a very wet mouth breed, Im not a fan of drool, but if I could take in a rescue then things might sound a bit differently. I dont mind hair or grooming, but Im not going to get a standard poodle until I can afford to keep it well groomed,
So, to sum things upp, I would not go out and get hunting breeds, hounds, most nordic breeds, large mastiffs, and most lapdogs. This is not because I don't like them, by no means, just because they don't fit into my lifestile and they likely would be happier with an owner that is more involwed with them.
