In Dr. Bindernagel's first book on Bigfoot, North America's Great Ape: The Sasquatch, he talks about how Bigfoots are not too fond of dogs. Apparently Sasquatch do not tolerate aggressive behavior and probably don't appreciate being outed by man's best friend.
Attacks on Dogs
The violent reaction of sasquatches to the proximity of dogs has appeared in several reports. In one of these, Jay Roland, of Willow Creek, California told of finding bigfoot tracks near his campfire at night after two hounds had been killed by something they chased in the dark.
He told John Green the hounds had been torn in two.18 Mike Corey of Yakima, Washington told Roger Patterson that his dog had attacked a sasquatch near his house. He went out with a gun and shot at it as it was running off. Later some-thing fatally beat his dog."
John Green recalls several reports of dogs being slammed against the side of a house and subsequently found dead with broken bones. Because there was no track or sighting of an upright hair-covered animal associated with these reports, they went unfiled.
Crypto Blast Editor's note: Hey guys, DeeCee here. I just wanted to mention that Bigfoot TV personalities Bobo and Cliff Barackman from Finding Bigfoot and Rictor Riolo from Bigfoot Bounty have all taken their dogs to Sasquatch locations and have not had a problem with their dogs. Xochitle, Monkey and Abby are very well behaved and always stay close to their masters.
