I'm a strapping young male Rotty, so about 50 kilos (110 pounds). I don't have to do the heavy gravity thing because I am heavy! Mum and Dad can't lift me at all anymore.
I did nip dad one night when I was younger, and he grabbed my scruff, threw me on my back onto the floor and snarled into my face. It scared me so much I wet myself! I haven't nipped since, but I don't like being moved when I'm sleeping. The louder I growl, the more I'm actually shaking, and one night I shook so much the bed vibrated against the walls. Mum gave me cuddles, but it took me a few minutes to stop shaking.
I'll probably grow out of it in time, but for now it's just annoying. And at least I'm allowed on the bed to snooze, unlike other poor doggies who have to sleep on floors or even (ugh!) outside!
Max, the ferocious and mighty snugglepup.
