Looks like you're wearing him down, girl!! Just don't jump at getting THIS dog if he's not perfect for your family just because he's the only one hubby agreed to meet.
I agree, he may resent the decision if he's not 100% on board. Let him make the decision. Tell him CALMLY it's up to him so he can't come back later and say you badgered him into getting the dog. He has to want the dog, not just want to get you to stop nagging. Sorry, I don't intend to be mean, I just saw this same thing happen to my parents. My mom wanted another dog so bad and ended up nagging my dad until he said, "whatever you want, dear" then he complained about the dog a lot at first. Some people really need to plan their spontaneous decisions. I'm kind of like that so I can understand where he is coming from.
