Some are absolutely. My sister used to raise rottweilers and they left a lot and I spent months having to housesit and feed the bastards. They were all so naughty and big. I got hurt a few times by escapees who'd go through me for freedom.
One was nice though and would tuck me in at night, the only one in the house. She'd put me to bed, lay with me, and then go get in her bed. But most of them were kinda awful.
So adorable thoughI still enjoy the 1st one more. I just love big dogs though I hate all dogs... (╬ ̄皿 ̄)凸
