Would there be any concern about somanila(sp?) because the snake is 'licking' your face? Sorry if this is a stupid comment!
The only animal I get face to face with is my golden and only because I trust her 110%. I don't think you can establish that same level of trust with a snake as you can a dog. Some might disagree but that is just my opinion.
I won't get face to face with my other dogs either....rather it be because of bad breath or because the one gets cranky when she isn't feeling good.
