I have a 100 lb mastiff. The only time there are fights is when some idiot is walking their fireball off leash. It's always the ankle biters that pick the fight. Big dogs have enough confidence not to be aggressive. That and my place has been broken into several times before. Slum building, windows aren't secure. When an intruder hears that bark, and sees an angry pooch with 2" canines, they pass on by.
Well i have one its just that he a mix and does not have a high pitched bark kind of in the middle tone he chill and not yappy . But i agree that small dogs suck they are awful stupid little things the suck they hate the out door when my dog baxter dies im getting a husky or a golden reteveir
The closer a dog's size is to a wolf (the original) the less likely it is to experience secondary biological contradictions due to unusual size.
They bark less, in my experience...
They feel more comfortable around humans and other dogs (in general) because they feel less vulnerable.
Last but certainly not least, you can have sex with bigger dogs! Yay!
