Husband tells wife "It's me or the dogs"

[Catherine]

I found an article the backs up the first story. It seems many people would have chosen the dogs over the partner.
Do you really want to keep a guy who would issue an ultimatum in the first place. Your pet would never do that to you.

I think a smart move would be a pet pre-nuptial agreement. The future partner agrees to the pets and puts it in writing. 
It could save trouble later.

I had a roommate who agreed to my cat until I had moved in and then she wanted me to get rid of him. 
We went our separate ways and I have never spoken to her since.
