We're pretty new to dog ownership, only ever had 1 very laid back elderly rescue before. Our pup is 14 months old. He was playing with his ball when it rolled under the sofa and he couldn't get it, DH knelt down to help and accidentally kneeled on his tail, he's 6ft and 14 stone so a lot of weight pressing down which obviously hurt him. He instantly growled and snapped at DH. As DH was down at his level the dogs tooth caught his lip, it bled a tiny bit. I didn't see it but DH didn't feel he deliberately bit him.
I just wondered if this was a normal reaction for a dog?
