If you come within grabbing distance of my 10 month old's hands, she will try to grab your hair.
We do try training her. She doesn't listen. Maybe we're over-indulgent parents
What with our dog's lick risk and our baby's grab risk, maybe we shouldn't go to the park where strangers will assert their right to sit within licking/grabbing distance of dog/baby when they have an entire park at their disposal.
To be honest, even if I didn't have a baby or dog with me, I'd find it pretty weird that a stranger come and sit THAT close to me on a park bench if there are other places to sit.
But, again, this is really a non-issue because it's never happened to me and if someone did do that (unless they wanted a friendly chat about something which is fair enough but then they'd have to take their risks with a dog-lick or baby-grab) I'd be the one getting up and walking away.
Even the most perfectly trained dog or toddler may also sometimes break rank (as others have said). I really can't believe a random dog-lick or a baby-grab (under the circumstances described, a dog or toddler who runs up to you is something different) is something to get hot under the collar about. This thread is downright strange (although I'm guessing it's not a representative sample - after all, the vast majority of people who couldn't care less probably wouldn't even bother replying!).
I'm also interested to hear how all the people with dogs who are trained not to lick have done this with adult dogs. My old boy is 11 so probably way too late for him now but the dog trainer we used when we adopted him never even mentioned training not to lick. We had our work cut out with the basics when we adopted him (stay, bed, down, sit, walking nicely, recall, not barking when left, behaving nicely with other dogs) and we weren't totally successful (recall not perfect, still barks if left) and training him not to lick (not that he licks excessively) seems ott. Again, we've never had a problem with him licking a random stranger, but I'm sure it could happen if someone came up that close to us (again, pretty weird situation which has never happened).
