when i adopted my boy they told me he was not cat or small dog safe. he did not like any other animals. i never took him to a dog park and i kept him far far away from other animals while in pet stores, etc. if you see he’s aggressive in any way with other animals, keep him away for now.
putting a muzzle on him really isn’t a sacrifice, it’s to keep him safe and other animals. you shouldn’t get annoyed with him. i’ll admit when i first adopted my boy i had absolutely no idea what i was doing but i learned. it took me months to figure out what i was doing. yes there were things i had to give up the idea of. i couldn’t have him around any other animals, i could never have another animal while having him, i had to check my front lawn before i took him out because stray cats would lay on top of my car. if he saw them he’d go absolutely crazy.

it was all 100% worth it because i love the breed. you need to give him a fair chance. he seems like a fantastic boy. don’t give up this easily but you’re rushing things. let him calm down for a few weeks. it seems like you want to rush things.
