Of course the ultimate question about a coyote vest for dogs is does it actually work ? While we have not tried a vest on our dog, the video below shows the protection the vest offers during a Police K9 attack scenario. The police dog, a Malinois, lunges and sinks teeth into the vest wrapped around a Policeman’s arm. The video shows that this aggressive and strong attack did not result in puncture holes in the CoyoteVest.
This is an impressive video and one other factor to keep in mind is that here in the video the vest does not have any spikes nor stiff whiskers. In a real scenario, the vest would also have hard spikes or stiff, bristle whiskers. It seems that those additional features would make it even harder for a coyote to actually bite down fully like the police K9 is doing in the video.
