I think your spot on Duane... A dog like that would have a real tough time keeping up with the others for sure, and it might even take a toll on their hips and shoulders after awhile, but man oh man would I like to see a Fila or a Tosa catch a hog!
About 8 years ago, in Phoenix, I got up early one morning, and was drinking my coffee, and Buster, the black dog, is standing at the back door and he wants out bad. Hackle up, tail straight up and vibrating!
I walked over and look out the sliding glass door, and on the back fence, there was a HUGE hawk just sitting on the fence taking in the sun.
The hawk was high enough on the fence that I knew if I let the dog out, he'd just fly away. Well, the plan looked pretty good on paper anyway.
So I slide the back door open, and Buster is out like a shot! Now, the Tosa is a funny dog, because they don't really ever bark, and when they're scrapping, they stay pretty much silent. In Japan, when the dogs are doing their "wrestling deal", if one yelps out, or barks, he is immediately disqualified.
ANYWAY, Buster is out the door like a shot, and he's tearing out after that great big hawk, and he's closing the distance really quick. I'm thinking, "well, this is gonna be interesting"...
So there is Buster going about 100 miles an hour after this hawk, and just when Buster is about 8 feet away, that hawk turns his head, real slow, and looks right at Buster, as if to say, "are you sure you really wanna do this?"
I have NEVER, in my whole life, EVER seen a dog stop and turn around so fast.
Buster hit the brakes, and before his body stopped it's own forward motion, he was beating feet the other direction, and HE was getting the HECK outta THERE!
He ran back into the house and stood behind me and just looked at me like I was gonna protect him. I never laughed so hard in my life.
165 dog gets buffalo'd by a hawk.
I sure do miss old Buster.
