Dogs even though domesticated are still animals and you can never fully predict what they may do. I was attacked by two dogs that ran from their yard. The smaller of the two was the aggressor and nipped me first. I was then attacked by his companion, a black German Shepherd.
I wasn't afraid of the little dog, and really thought he was running out to say 'hi'. I was shocked when it bit me.
It seems that we are trained how to respond to a multitude of situations, but I'm not sure there is a correct response to a dog attack. My response to the first attack by the Shepherd was to strike out which I did and have deep bruises on my arm. I wasn't expecting him to attack a second time, but when he did I put my hand out because he leapt for my face. The dog grabbed my hand.
Six days later, I am still recovering from the shock of the attack and the wounds on my body. From this point forward, whenever I go for a walk in the neighborhood I will carry mace.
