Fact - When I was a kid, I was the girl who could tame anyone's dog. All dogs loved me, even dogs who bit other people would come to me. Now, I'm afraid of big dogs. Totally afraid. It affects my basset, which is terrible. She's now afraid of them too. We're working on it a little more with every walk/adventure.
Fact - I worked for a Vet as a receptionist for about a year. That's where my fear started. Our office manager had this big vicious dog but I had no clue he was mean. I went to pet him (he was fine with it. I actually had my hand on his head) and she FLIPPED out. Then the dog flipped out and came after me and he hated me after that. She kept him in a big pen in the back and every time I would walk by he would bark and snarl and try to get me through the cage.
