<human>: I'm an animal lover, always have been- grew up with many, many cats and have always wanted a dog. He grew up without any pets at all, and has never had the inclination to have any. 

I have mentioned many times that in the future, I want to have a dog. This comes from childhood memories of my grandfather's pitbull-boxer cross that my mother and I went over and took care of everyday after my grandpa became ill. She was the sweetest thing. Anyway, when I mention this my boyfriend gets very upset- all he sees are the negatives to pet care- the poop, the chewing furniture, the never being left alone etc. (which are all valid parts of pet ownership).

We want to be able to find a compromise, but there doesn't seem to be one- either we get a dog or we don't, and in those situations one of us is left unhappy and resentful. 

He has said that as long as I sign a contract saying that he never has to pick up any poop throughout the dogs life that I can go ahead and get a puppy. However, this doesn't sit well with me- what about when I'm sick? Or really, really pregnant? I have told him that I am fine to pick up the poop but in certain situations (like the above) I would really appreciate it if he stepped in, and he says he wont.

Condense the text into a few key points
<bot>: I desperately (in the future) want a dog, boyfriend despises idea- is there any way to compromise without one of us feeling like we just straight up lost?
