Animal rights.
I've had an AR nut who constantly tried to let my dogs out into traffic, down to stealing the padlocks on my gates then leaving them open. I live on a VERY busy road.
Jokes on her, not only are my dogs never out unsupervised for more than a minute or two so easily recalled, but they're trained to avoid traffic like the plague. Once, I went out and checked the gates were locked with the loops over the top (they're padlocked, loops over the top AND springed to close automatically) at 9am, let the dogs out, went in to check on my infant son, came back out at 905 and the gates were both wide open, locks gone and springs disconnected.
Ten minutes later, animal control showed up and fined me for dogs roaming at large. When I asked what time the call was made.. it was made before the dogs were even outside. They dropped the fine when that happened, and have actually been assisting the neighbours in securing fencing ever since. Now when I go inside to check on something, the dogs are brought in with me.
There's a reason EVERY decent dog owner here has spare leashes and extra tags on their dogs. We text each other when another dog is out loose, and have kind of a neighbourhood watch on each other's fences. It happens in fits and spurts. Every day for two months multiple dogs will be roaming, and then she stops and all is peaceful. Then she starts up again.
Once, I rescued two dogs who had been jammed to a fence by their collars on a blind corner in the back lane, half hung. It was VERY deliberate, the collar was hooked and looped so the dog's head was jammed down between the boards. I had to cut them loose.
I can't set up a camera because I get literally hundreds to a thousand pedestrians passing the house every day, I live on a major road with a bus stop in front of my house. When we moved in, I deliberately removed the gates so that you have to go to the quiet side street or my back lane to access the yard.
One day I will actually catch her doing it, and then I will nail her to the wall with trespassing, dog endangerment, and all the fines people here have collected for dogs at large. I know perfectly well who she is and she's gone at me verbally for having dangerous dog breeds and too many dogs before. She thinks I'm hoarding, because I have different dogs every 6 months - I foster for rescues.
I just realized that the fence hasn't been touched since I boobytrapped it a few months ago. I haven't had to go out and close the gates. Either that, or she doesn't like Dobermans..
