An adult 30-35lb coyote = 1 very tough determined dog. Thats, willing to take a beating & not stop[alot of Heart]. Until he/she wins.
A "fresh" short ran coyote. Is a blur in a close quarter fight[Buzz-Saw].
Personally, I've never seen a domestic dog fight as fast & furious as a coyote. Especially, a fresh coyote.
I guess you have never seen a well bred American Pitbull Terrier or an American Bulldog from hog catching lines in action. Either one would absolutely DESTROY even the biggest of Coyotes.
I also disagree with your theory on a coyote or any other wild animals ability to fight with heart and not quit until they win. Wild animals only fight for one of a few reasons. Those would be Breeding rights, Food, territory, and self defense. In most all of these cases, the fights are pretty short lived, once one of the combatants realizes he is over matched.
In the case of self defense...say from a domestic dog, the animals will usually only fight long enough to gain an advantage in flight. First chance it has to escape, it's going to turn tail and run. That's probably the best survival instinct any wild animal can have..it's instinct to run from danger. There are some truly incredible, much lesser known breeds, that are game tested and bred for either canine combat or hunting combat.
Breeds like I mentioned, as well as the Presa Canario, the Dogo Argentino, The Fila Brasilleo, Cane Corso, The Tosa inu, etc. Some of these breeds can also track/course the game, yet still maintain the energy to fight and kill the quarry once the chase is over. The majority of these breeds are extremely rugged and bring biting power like a steel bear trap to the fight. I have seen dog's literally break bones of other dog's, with one bite...a bite that they will ONLY relinquish, to get a better bite/hold. (unless you either kill them or pry their jaw's apart with a breaking stick)
Add the fact that these breeds were bred for centuries (in some cases) to be "Dead Game", (to never, ever quit) and you have one hell of a warrior on your hands. A well bred version of any of these breeds would rather participate in combat than eat. Trust me when I tell you...A yote wouldn't stand a chance.
Go watch Jay Dorsey's "trophy hunter's lodge" Hog hunting vid. They use American Bulldog's as catch dogs for the hunter's who wish to kill a hog with only a knife. You will be amazed at how a dog can run in and grab a WILD Razorback by the head and make it scream from the power of it's bite...then shake it like a rag doll, all the while holding it and NEVER letting it go, so the hunter is SAFE from the tusks while he knife's it.
I actually think a Yote would be a joke for any of these breeds. I can picture ONE BITE and a crushed skull or broken bones crunching. The yotes best chance is to give the dog mange or rabies.
