I don't know what to do. Our dog bit our 5 year old daughter today quite probably unprovoked. She fell down in front of him and I assume it woke him and he bit her hand (I was just inches away but didn't see or hear anything until dd started crying). I am of the opinion that a dog that bites someone should be put down - but I was thinking of the type of bite that draws blood - or am I just making excuses! The dog is 11 years old and I could make excuses that he was woken suddenly or his eyesight is failing or he's turning into a grumpy old man. But I have a 2 year old too and if I do nothing and he bites again, only worse, I've only got myself to blame right! I'm not over reacting am I, or am I ???
