I guess I'd first look at where ya live, town country or the city. I'd next look into or think about the crime around yer place. If I had a 7 year old, I'd be thinking protection first then noise. An ankle biter will wake you up and make enough noise to let you know somethings wrong, but an ankle eater, will put his life down before anything ever happens to his master. We live in the country. We have a Husky-Akita, and she loves to ride in the truck. When we're in town, she puts on the show that she's aggressive, and I like that. Everyone downtown knows we have an "ugly dog" but she's as sweet as can be in reality, yet, don't come sneaking around with bad intentions, especially at night. Protection first, cuddly second. Just my opinion.
