I saw that porcupine-dog get-up on shark tank. Mr. Wonderful told the inventors they should electrify it. They already had a model that would would shock an attacking animal (if the owner with the remote control was nearby).
A couple of years ago near me, an owl scooped up a small dog and flew off with it as the owner watched. It’s amazing how much birds can carry. At our last house, there were houses on the water, a road, and then our house was on the opposite site of the road. Several times a year sea gulls would drop fish on our deck. And these were fish about the same size as the gulls.
In my neighborhood, several neighbors have posted on Next Door that their ankle biters had been pinned down by hawks/owls.
May sister in law lost a worthless, yapping, vicious little Yorkie to an owl. I applauded the owl.
