Grwndi used to do this a lot,bite your finger/hand if you were fussing him. He stopped it for a few years and he's started this again the last 2 weeks. The only time he comes for a fuss is when we're in bed and he jumps up and lies on the bed we fuss him and then we put our hands down and he bites them then licks it,why does he do this? We have recently had a puppy (8 weeks ago to be exact) could he be telling us something that he's not happy?
