Everytime I take Yoyo outside, he freaks. He puffs up and black beards at me. He even trys to bite if I go to pick him up. If I hold him he trys to jump out of my hands and run. Now will he eventually get used to being outside if I continue to introduce him gradually or should I just give up taking him out? It really seems to be quite stressful for him. I only take him out for a couple of minutes at a time.
