New Born Pup
one of my (21M) friends (20M) guinea pigs is shaking them off, and generally seeming to not want to be touched when this is happening. my friend will continue to pet them, which consistently leads to him getting bitten. he says he can teach him not to bite, but i feel like the biting is a clear sign that they aren't enjoying it. he thinks the shaking off is popcorning and the biting is due to excitement. to clarify, these are not at all gentle or affectionate nibbles and seem very aggressive to me, friend has bled quite a few times and has many scars from these bites. they bite after about 15-30 seconds most of the time. they are both regularly handled upside-down/ without supported legs which i know is bad (friend thinks its fine because they know his scent and usually dont struggle/exhibit obvious stress) , so i am worried that my friend is badly misinformed on how to properly handle them, i am an animal lover and want to make sure they aren't accidentlly mistreating their pets. thanks for any help.
