Dillers smell just like a pig and our young dogs trash on them occasionally. Best thing that has worked for us and has been a long time trash breaking technique is let them go ahead and catch it. When it kills it take a piece of mule tape and tie that driller to the dogs collar and let it ride the dog for a week or so. I promise you that dog will hate a driller so bad after that it wouldn't bat an eye at one the next time you run across one.
my dad had a ab that would chase all his chickens and kill them. so he zip tied a dead chicken to his collar and left it on there until it stunk so bad that you could smell it as soon as you went in the back yard. me being the son, my dad had me go cut it off, the daggum dog picked it up and finished eating what was left and went after another chicken! needless to say, my dad built a chicken coop the next day haha
