hey i'm new here and this may sound really really stupid but do you get different kind of chihuahua other than longcoated and shortcoated? Just wondered cos i really want one that looks just like the one in mia's signature but it looks totally different to, say, Britney Spears' dog Bit Bit but i guess they're both short? sorry if i'm insulting people with my ignorance! lol. which kind is the most common? thank you!
