Keep them out of scraps until they are a full year old at least. Size and breeding are all for not if you ruin them by having them whipped by a predator they are not ready to handle. Despite all the bluster, they lack the mentality and physical abilities that will be developed over the next year and a half or so. Raccoon kittens and opossums are OK but not coyotes for such young dogs to engage.My dogs are going to earn their keep...the other night, I could hear them going up and down the fenceline bordering the woods, barking a very aggressive bark. Something was out there, and even though they are not quite 6 months old, they were defending their property. It apparently thought better of venturing out of the woods and went away, as the dogs settled down around midnight and didn't make another sound until morning.
A couple nights before that, one of the dumb roosters decided he was going to camp out and not go in the coop at dark. When I grabbed him, he squawked very loudly. The dogs boiled around the corner of the house (they hang out on the deck where they can see out over the back pastures and most of the coops), screaming for blood and only laid off when they realized it was me and not something killing the rooster.
And...I recently learned we have coyotes in our immediate area. I'm so glad I got two dogs...I was only going to get one. But now, with two GPs, I feel better about my stock being safe knowing we have a bold pack of coyotes out there, better about my dogs' safety as a team, and better knowing I have very large dogs bred to handle such predators. I hope they never have to though.
