A lot of dog owners do it be they are self-centered DUMB-ASSES!
Any time you go to a city park, the beach or even walking on a sidewalk you see dogs not on a leash and piles of dog shit everywhere.
The other day I was walking on a sidewalk with my little girl and we stopped as an off leash dog took a dump ten feet ahead of us on our walk.....guess what the owner did? JACK ALL. Just left a steaming pile of shit on the sidewalk. We caught up to him and I politely(as my little one was there) asked him to go clean up his dog's poop...He said no..I then started dialing the cops on my cell phone and told him he had three seconds before the call went through. He then went and picked up the poop. The police here are pretty Nazified which can be good and bad...good to fine dumb-asses like this. Now these are the dumb-asses I am talking about.
I have been up to Washington Pass, Back of the lake at Lake Louise and many other climbing areas where dogs were loose running around whining and shitting everywhere. I don't hate dogs..I had them growing up but we were respectful and considerate of others but it seems for the most part those days are over.....Just a bunch of fucking idiotic dog owners with no respect for others or the environment now.
That's my three cents!
