Ever been attacked by a pet?

Some pets turn against their masters for various reasons. I remember one time when I stepped on a pet dog's tail and he growled angrily out of agony not hatred as his furrowed brow suggested. The funny thing is that he just lightly placed his teeth on my leg and it was like a playful bite. Stories abound how people manage to tame wild animals especially carnivores whe young only for them to turn into Frankesteins monsters later on.
