Puppy!!!
You could always send your boyfriend over to my house and have my dh explain to him about the love of Yorkies

lol!
If this is being to nosey then just ignore me

lol! Have you guys been together long? Is it your house or his? I personally would take these factors into consideration if I were you. If it is your house, not the both of your's together and since your not married yet, I would probably make the decision that I wanted to.

But if you guys are very serious and have future plans i.e. marraige and it is both of your's home, then I would seriously take his thoughts into consideration. Even though he should always vote for another puppy, lol!
HTH!
Please don't take me as being rude, just some food for thought
