Alberta Fish and Wildlife have used them to assist in problem bear control. There is probably info on the web about this.
How about a Bernese Mountain dog or a Great Pyrnees?
Both are great breeds. I am hoping for smaller and more agile. We do have a stray mountain lion every once in awhile in West Virginia. However the main problem is coyotes, overly curious black bears and rednecks jacked up on crystal meth.
