Here is more information that is documented scientifically.
Coyotes are becoming bigger and more ‘wolflike’
I know what I see, what I'm living around and what has been killing pets and livestock here. Experts say it's "Uncommon" but does happen, and I'm telling you "IT IS HAPPENING HERE" Wild or feral dogs and coyotes are pack animals, territorial and the ones captured in our area ARE BREEDING, we have have "coydogs" we have feral dogs and we have coyotes.
The research from Virgina wildlife and TN TWRA shows that these dogs have Wolf DNA, domestic dog DNA, and coyote DNA.
whether they are technically one species or the other, or even a mix of 2-3 doesn't change the problems we have with them!
Every single night I can walk outside and hear their calls, their yips and barks are distinct.
Every single cattle herd here has donkeys, to keep the coyotes or dogs away.
Everyone here can tell you about these animals, they are a nuisance and have killed many many pets.
