My wife convinced me to take a Chihuahua with one of her "you can sleep on the couch forever" motivational speeches, but I have to say that I love the little fella.
I'm just glad that he isn't a rottweiler because he can be vicious with outsiders who come to the house.
I once read that small dogs like that are better guard dogs because they will not actually attack an intruder, they will bark up a storm but stay away so it’s hard for the burgler to get them and stop them. Don’t know if that’s true, I just know anything is a better guard dog than my golden!
