sorry, i only read your first post, so hopefully i am not repeating what people have already told you.
well, you are on a forum with a bunch or yorkie lovers, so of course most of us are going to say. the bigger one!!! the bigger one!!!
that said, it depends on your financial situation. if that extra $100 puts a strain on your budget, than i don't think it's a good idea to do so. if it doesn't, than i think that it's a really good deal!!!
i know the apartments in my area will charge $100 just for having pets. you get the same size room, the $100 is just to pay for having a pet in the apartment.
i personally don't like it when people think we are silly for treating our pets the way we do.
i think it's kind of rude. i don't tell THEM how they should spend their money or how they should treat their family members. so why are they telling us that we are crazy!?
