Dogs could also have been lost to someone using the old time method you described.Cant say if this is right or wrong, my daughter n law was telling me her grandparents control coyotes in their area by soaking sponges in bacon grease and placing in woods around their wooded property. She said that the animal eats it and dies. I guess old timer method of ridding the area of predators. We have a pack of coyotes around my place, seen on cross road and go into woods 1/8 mile down the road and my neighbor 1/4 mile down same road in woods has recently lost 4 dogs to coyotes. ( pet dogs )
Haven’t had any issue with my secure run or coup- yet....
