I'm going to refuse to sleep with my boyfriend's dogs
Why don't you want the dogs to sleep in the same bed?
Beds are for people and dogs should sleep on the floor.
I can understand how you are feeling. You should treat your pets like they are part of the family. If it is making you uncomfortable though, you should talk to your boyfriend about it and the way it makes you feel.
We'll talk about it, but I'll break up with him before I sleep in the same bed as those flea-ridden mutts.
It sounds like your boyfriend really loves his dogs and treats them with affection. If you're going to continue the relationship, you need to start being more humane to the dogs. Your boyfriend might not think you have a big heart.
