Wondering if anyone has any advice please. I have a 4 month old beagle puppy, whilst on a walk today he was biting at my OH feet, when my OH told him to sit and pointed with his finger puppy jumped up bit OH finger and drew blood, my OH was so shocked he stepped back wards and puppy then jumped again and clamped down on OH thigh biting through his trousers. Is this normal behaviour for this age as it seems abit vicious?! When he gets over excited he does the same and will snap at finger when told to sit, so we have started to say NO and walk out the room and return in about 1 minute to see if he has calmed down. Other than that he is a lovely dog and we love him to bits! Need advice as really concerned he will do this to a child or someone else.
