I live in a multi-dog, multi-poultry household which at the best of times can be fairly chaotic. I know this dog from previous experience, comes into the house and pees and poos as a welcoming gesture. I also don't know how the dog behaves around poultry. They have been before and there was a dead chicken when they left. I don't know if this was because of the dog, but we have not found dead chickens in the garden as a result of our lot, but it is entirely possible.
My experience of other people saying it's ok to bring our dogs into their homes when there are lots of other dogs present is not good, and although we do look after friends animals from time to time, I know there will be a lot more pee and poo to clear up in the house, and frankly it can become a bit tiresome.
I am not a happy bunny and my brother does not think like most people, so having a sensible conversation is not possible.
