Used to have a beautiful Springer Spaniel I bred and raised in our kennel.. he became my sons dog, and the two were inseparable... A neighbor stopped by one day and grabbed my son, as if wrastling with him in fun, and the dog bit him.. not terribly, but enough to make him back off... My son was rather proud, but I was quite upset... about a month later, my daughter was babysitting a toddler in our house... she saw the dog come around the corner and put his hair up, so she reached over to pull the toddler back, yelling at the dog, and as she did so the dog lunged forward, and ended up biting my daughter pretty badly..
He had his shots etc, so no worries about rabies... but we went for a walk and he didnt come back.. I loved that dog as much as my son did, but kind of like owning mean bees, I will NOT own a dog that bites.. I hold no sympathy for anyone that would, nor any mercy if their dog bites someone in my family.
That cat in the vid impressed the heck out of me.. I have to say, that is the most astounding thing I have ever seen a cat do, and it is not something I would have EVER guessed a cat MIGHT do.
