Just like you I have always had trouble with animal shelter visits. Until I found the ANNA shelter. I think that the 2 ladies who run this are amazing and I had to share this with all of you.
I'm attaching a link to their site. Scroll down to the middle of the page where it explains their facilities. I wish that there was one of these in every city.
