Dude, not to frighten you but let me tell you a story about my dad. He was a mailman, he was delivering mail to a house that had a dog. He was invited to talk and to play with the dog often, so he stopped in for a chat every once in a while. Anyway, one day he was talking to them, and the family dog hauled off and bit him for no reason, he barely noticed it, that is until blood starting running onto the mail. He thought it was nothing and went along on his business as usual. He was bit by a gigantic Great Dane. He had swelling, and began to feel sick the next day, so he went to the doctors. To make a long story short, he was hooked up to some very powerful antibacterial drugs that was administered into his arm via shots. But, the needle was in his arm at all times, and the fluid was kept in a sack strapped to his waist. That drug was on constant flow for 5 months straight until that bacteria from the dogs saliva cleared out. He honestly has never been the same since, and I think it may have stemmed from the dog bite causing a chemical imbalance, and that imbalance was only worsened by those drugs.
Anyway I would go see a doctor right away if I were you.
Woah, i had a great dane when i was a child, thankfully it never bit noone except a robber who tried to rob our house.
the owner should be responsible for all the damage because he should know whether the dog has any diseases. and dogs and cats should always be taken to vets for check ups, took my dog every week.
