OMG she's a lucky girl !!
I would have freaked out too but am so glad she's ok.....
My neighbors came home to find their poor dog hanging from his leash and collar outside...it's something people just don't think about...
and Betty'sMom..I'm with you - I walk my yard EVERY Day - have ant stuff at hand and bug spray just in case....I'm always outside with mine but on days that the slider door is open they do come in and out on their own...I'm glad they like to be by ME 24/7 because it's rare they're ever outside by themselves
