Good to know that bigger yorkies are common too! I thought my dog might have just been some kind of yorkie-maltese mutt because he's not 9 pounds. :P
But that's awesome to know. Six miles is a pretty decent hike, so that'd be just fine! I think I'll still talk to my vet about it and see what she recommends, but I'm definitely interested.
Thanks!
Anyone else have another number, or does 6 miles seem about accurate?
