One of my brothers is hosting myself, DH and DD along with other brother and SIL for the night. We're having a takeaway this evening and just have a generally nice time. Dad was also invited with Step-Mum, we have a fractious relationship as he was quite abusive when we were younger, which may or may not add context. Dad said he'd only come if he could bring his dog.
My brother had told him that if he brought the dog with him, he'd have to keep him in the kitchen because they have two cats, and our DD is terrified of my dad's dog after he knocked her over and kept trying to hump her last time she saw him. He's very badly behaved and my brother didn't want the dog in the house at all, but agreed on the compromise of having the dog in the kitchen until they went to their nearby Air BnB for the night (there isn't enough space for Dad and Step-Mum to stay here, plus they found a dog friendly place to stay which made more sense than leaving the dog in the kitchen all night).
Anyway, long story short, my Dad has driven 3 hours down to visit and within 15 minutes has left my brother's house after having a huge huff, because he said he wouldn't put the dog in the kitchen and immediately tried to bring it into the front room. My brother said he couldn't do that because of DD, nephew and the cats and he wasn't happy.
Dad has flown off the handle, said he doesn't feel welcome and that it wasn't fair on him, or the dog. Dad said he felt that it wasn't fair on the dog because the dog might 'chew things' if he was left on his own, but my brother feels like he told Dad from the start that the dog was only allowed in the kitchen and it's his house and his rules.
My brother is really quite upset, have we been unreasonable by not chasing him out of the house and telling Dad to stay?
