As noted the problem is not the dog but the idiot owners who have no clue. I probably love dogs more than anyone you ever met, lost our last, a Greyhound rescue 18 months ago to the Rainbow bridge... sigh. Thanks to all the fine dog owners who permit me to pet your pooches, it helps a lot.
My personal rant is regarding those stupid extended leashes, push a button and Fido now has 30' of a leash to exploit. Virtually every campground I have ever visited requires that dogs be on a 6' leash and these DO NOT qualify.
Our Greyhound, as gentle a soul as ever lived was attacked more than once by dogs at the end of the 30' tether while their owners were outside of our site. Google these leashes and you will see the carnage they can provide to the person on the other end of the leash. Many have lost fingers and or been tripped up and fallen with disastrous results. They are in fact rated as one of the most dangerous consumer products you can buy.
OK, Rant off for now. It would help to take my dog for a nice walk right now but alas I remain one dog short.... Someday another pooch.
