Today I had Caramel out on his harness and leash cause it was a beautiful day when all of a sudden our next door neighbours large dog (boxer) comes bounding towards us. I scooped up Caramel and started to go for the door. This dog is good around cats and Coco and him get along, he was just being curious but Caramel has never ever seen a dog and he lost it. He hissed which he has never done before (he is a year old) and growled/spit and wouldn't let me take him inside, he was fighting me. His tail puffed up and he began to scratch me. I finally got him close to the door and the dog was still following us, and Caramel was still fighting, when all of a sudden Caramel latched onto my forearm hard. I got Caramel in the house and realized he had sprayed all over himself and me but he was ok just a little shaken. I then noticed that my arm was dripping with blood! How could Caramel's little teeth do that! There are 4 pierce marks, and they are very deep. I washed them and all my scratches with antimicrobial soap and then rinsed them with alcohol. That was hours ago and I can hardly move my arm. I don't know if I should go to outpatients or just ignore it? I know that bites are dangerous because of all the bacteria in the mouth, and I know that you don't want to let an infection spread, but maybe my arm is just bruised? Im not sure what should I do?
