My 10 year old ddog has bitten me, puncturing the skin and causing quite a deep wound. She has an injury on her leg causing her to have stitches and as I was cleaning her wound, which I have done for the past 10 days without issue I must have accidentally hurt her and she snapped and bit me. She has never reacted like this before so am not worried about her biting but the bite itself is pretty deep. Advice online is quite conflicting, do I need a jab??
