I had a rescue dog who had been repeatedly attacked by another pet in his former home and was reactive and scared of other dogs. There's a trail near my house on private property that is generously open to leashed dogs only. I used to take him there to walk him for his safety and everyone else's.
The number of aholes with unleashed dogs back there, and who did not scoop the poop. I swear. Anyway, RIP Ace the Bathound, I miss you buddy.
If I’m in a park on a trail I should be able to watch for birds, and not for bulleting unleashed dogs or uncleaned up dog shit. I have also discovered a surprising number of dogs that are reactive to brimmed hats, like Alex Tilley had personally insulted their mum.
