Ferrets
.
Not real tactical, 'cept they will actually try and defend you against attacking dogs even when outclassed in weight 30:1 or more. Often with success. The craziest example I've heard of involved a 1lb teensy female ferret up against a 120lb Great Dane. The ferret won, and ended up in her owner's arms happily chewing on half a dog nose
. Note to dog: do not advance on some lady growling and then when her ferret bounces around at your feet growling and hissing, stick your nose down there to take a closer look. Very bad idea
.
They'll happily try and get along with just about anything: cats, dogs, rabbits, horses(!), whatever. Share food with anything, no problem. I knew a guy had a mouse problem in the house, he assumed the ferrets would deal with it, until he spotted a mouse run up to a ferret having dinner. The mouse got up on it's haunches. The ferret picked up a single piece of kibble and dropped it in front of the mouse. The mouse took it and ran off. The ferret went back to dinner.
The absolute best "protective dog" I ever heard of involved a family that was walking through the woods in Wisconsin and came across an abandoned wolf puppy. Cute little thing, they took it home, raised it on formula in a bottle and then dog food, and it did just fine...and turned out to be *really* friendly, not at all what the books say on wolves. Really affectionate, playful, harmless around little kids, the works. Only problem was, it was kinda "mis-shapen", like it had birth defects or something. So when it was around a year old and 80+ pounds, they took it to the local vet to have it checked out.
The vet was absolutely shocked. "It's FRIENDLY!?" Yup, it was licking his face as he petted it. At which point, he says "well that's a really nice WOLVERINE ya got here!"
Whoops
. Most members of the mustelid family tame really well, including river otters, sea otters, fishers, badgers and skunk. And of course the ferret and his close relatives the European and Siberian polecats. Turns out wolverines are the same way, despite their rep in the wild.
Can you imagine what would happen if somebody attacked a member of that family while the pet wolverine was nearby?
