Aw look, they are smiling at you! :p
Edit: Actually, my stepmother was attacked by a dog, and so was one of my uncles. They can be mean. I wasn't present for either attack, but as I understand it, my stepmother was playing fetch with the dog and it just turned on her. The dog who attacked my uncle was actually my mom's dog. I was an infant at the time so I don't remember it, but my brother was playing in the yard, my uncle drove up, walked up, opened the gate. The dog waited patiently until he was inside the gate, and when he made a move towards my brother, the dog attacked. It was likely a defense, the dog likely considered my brother her pup. He was still a child.
Anyways, point is, I love dogs but do please be careful with them!
