So we had an unexpected visitor this afternoon and to my surprise, the dogs were the VERY last to know. They squeal and bark at every squirrel and lizard out on our back deck but a 5+ foot snake slips by without a peep? I realize it is a very rare occurrence but come on!?!?! Me and kids watched it slither up the tree trunk, back down and then across the deck before they noticed. Oh My Word!
