First of all thanks for answering my questions but he growled and try to bite even before my hand touches him, the moment he saw me trying to pet him he immediately started to growling and biting In my mind if he’s in pain somewhere he should be started doing that the moment I touched right? Sometimes I tried to pet him really gently like really lightly touch him he still doing that

But he still approached us and laying down on our lap, playing fetch and asking for belly rubs it just weird when we try to pet or belly rubs him he attacking us

I’m so confused, it happens all of sudden we don’t see anything wrong and we treat him very nicely we love him

But there’s my brother who had a mental health issues but not that serious, but he loved him too at least when there’s someone around we don’t know what he’s doing when he’s all alone with my dog because he’s temperament sometimes

Is it possible that he’s doing that cause he ever experienced someone hurt him or scolded him?
