Coyotes kill large prey by strangulation. Their jaws are not sufficiently powerful to challenge the prey's spine, so they rely on strangulation/possible carotid artery penetration. They clamp onto the prey just below the jaw and don't let go. The reason that they grab "up high" is that a low grab makes them vulnerable to being dragged and stomped.

A coyote biting the bottom of this ewe's neck gets a mouthful of sodium fluoroacetate. Clans of coyotes, and coyotes that diligently stick to the business of eating rodents are at no risk from these juice pouches.
The engineered solution.
It would be very useful to be able to track released Gitmo detainees, especially if 30% of them rejoin terrorist cells.
Released terrorists are an intelligence asset. At a minimum, we need to know where they are. That is a trivial exercise with laparoscopic surgery, cell phone technology and GPS. Battery life would be conserved if the device did a daily "up periscope" at random times.
In some cases it would be useful to include microphones in the package.
Being able to pin-point the exact location of high-value targets gives the military the means to drop a guided munition on top of their head. A patient commander could wait until a high level meeting was in progress before dropping the hammer. No telling how many bonus targets might be killed.
A more passive solution would be to insert a pre-programmed devise with a small pouch of coyote juice. Inform the detainee that there certain places he must not go. If he violates the geographical constraints the device punctures the pouch.
The most passive solution would be to simply create a surgical scar at the base of their skull and tell them a device had been inserted. It will be necessary to implant a metal "dummy" in case the bad guys use any imaging technologies to verify the claim.
At a minimum, a released detainee will be less welcomed by his former associates if they think there is the slightest chance that he is carrying a bug.
