Re this thread, I think they are just "taking in" the smell of the other members of their pack. The pee licking won't hurt them, as I understand it.
Poo eating, depending on how much, can be more of an issue. Re the poo eating, is it his poo or other dogs?
Jack (my Basenji mix) only eats his own and his two "siblings" (Clio my mixed breed and Cody, my Basenji). I know it can't be good for him and I pick up in the yard every single day, but there are times when he gets to it before I can. At least I know that he's not eating diseased poop as my other two are healthy and he seems uninterested in anybody else's at the dog park or on walks, but it still can't be good for him. I have tried "Forbid" and tomato juice - I have even tried hot pepper on the poop as an aversion training thing, but nothing has worked. So, now it's just a matter of being vigilant. And, he's not eating copious amounts, but he probably gets a good nibble in every couple of days. This is probably way more info. than you needed! LOL!
