Looking for a bit of advice that has driven my husband and I crazy. We have 2 teams of Great Pyrenees (2 females, an unaltered male, and a castrated male). One of the females is 10 months, the other dogs we've had since they were puppies and are now over 4 years. We've spent a small fortune on 6 foot, non-climb horse fencing with welded-pipe posts. We have on maybe 3 or 4 occasions had neighborhood dogs get into our pasture or woods; our dogs have befriended them, I guess, because they won't do a darn thing to chase them out, even if they start terrorizing the flock. We lost a couple of pygmy goats last fall, and long story short, after the sheriff visited, the most aggressive of these neighborhood dogs was "disposed" of. No one in our neck of the woods keeps their dogs in a yard, just lets them run wild. Now, we were heartbroken about losing those pygmy goats, because they were very tame and like puppies with us, but they weren't monetarily valuable. My Nubian goats and Suffolk sheep ARE very valuable though. What do we need to do? A llama, donkey? A different breed of dog? We love our Pyrs, all are AKC registered and have on a rare occasion had a litter of pups which was a decent bit of income, they are great with my young kids... but my flock is much more valuable to me. Any advice? We only have 3.5 acres. Thank you in advance!
