Thanks everyone for the suggestions! I live in South Austin (as my friends say, I practically live in San Anotnio), so a trip to Waco would be a bit far, but I'll definately be on the lookout for yorkie-friendly places. Because of my job location and my BF's job location, we end up driving all over Austin, so there's nothing that's really too far away.
I might have to give the Barking Hound Village daycare a try and see how Seleena takes to it. Thanks for the suggestion! It seems like my friends, who have large dogs, just don't *understand* how much of a princess Seleena is, and why I care so much about where she goes, who she stays with, how she's treated, etc. Glad to know that there are others out there that understand.
