I'm so stressed out right now I don't know what to do. Earlier this evening I was taking my dog out for a walk. I happened to go by a friends house and stopped by to say hello. Her grandpa was also outside. I have a siberian husky and if you guys know their temperment, they are very kind and friendly dogs. Well her grandpa decided to come up to my dog without asking me if it's ok. My dog jumps on him and her grandpa rubs his head playing and all of a sudden my dog bite his hand. Now I have no idea what triggered this and I don't know what's going to happen. He has all his shots. My theory is that since they have 7 dogs at their house, he smelled those dogs and felt some kind of aggression? Since he was unfamiliar with this man, and this man walks up towards me, he felt the need to protect me? My dog wasn't playing with him, it was like a second he jumped on him and he bite his hand. Now he's in the hospital getting stitches. I'm afraid of getting sued. Or having to put my dog to sleep. I don't want to sound inhumane and pick an animal over a human, but I just felt like it really isn't my dogs fault. He was more or less protecting me. Basically the mans hand had a cut. Any input would really help me. He's NEVER done this before to anyone, he's always been very friendly to strangers. But there have been a few times where he barked at a person that was yelling at me. Protecting me? I don't want to have to put him to sleep, or get sued. I offered to pay for medical bills. Please help.
