It's the owner who makes a dog mean. But if you teach a dog to be gentle and calm, that's how it will be.

She gathers the laundry with her mouth and drags her dog blankets off the carpet so I can vacuum.

Don't stick us in the closet and throw the key away.

One time she went through a window to go get me help. She got glass stuck in her head. But luckily she was OK.

When I'm having a seizure, she holds me down putting her paws on my shoulders and sticking her nose across my neck until it's over.

And that is per owner not per dog.
