A person who is too much of a good listener and people automatically open up to them and cling to them like wet puppies. This is not the same thing as a baggage handler. Dog walker is a noble title that is only carried, if even unintentionally, by truly trustworthy individuals.
After collecting your beloved poochies solid waste in a "dog shit bag", during the cold winter months this bungle of fun can also function as a hand warmer! Much cheaper than a peacock hand warmer and all the faf of filling it with lighter fuel !
Warning, DO NOT pierce bag when holding or whilst inside your pocket !
-hey you want to go to that pregame with that girl and her friends?
* you mean the dogwalker?
-What?
*O she wasn't a DOGWALKER? Sorry I thought she was because her friends were just plain dogs!
Also "dog walker". A homosexual male, usually (but not always) rather effeminate. So called because of the greater-than-average percentage of gay males in the pet-care and pet-grooming industry, and the fairly common practice among gays as well as straights of walking dogs at the park or other public place as a way of meeting people.
"Man, check out those two guys over there with the pink poodles. What a couple of dogwalkers!"
"That sissy works for my veterinarian. The job suits him perfectly-- he's a real dogwalker."
