I'd be willing to bet your dogs were attacked by a mountain lion or cougar. In January, after we had fixed our fence and put electric wire all along the top of our field fence around our acreage, we had 2 baby goats disappear. I just thought maybe they were hiding somewhere. Then a few days later we found an adult doe killed, with her entire front eaten. She had been dragged through our creek toward the back of our property. Another doe had a big bite mark on her neck, and she too had been dragged through the creek. Sadly, we had blocked the only place our dogs could have gotten in the pen because the goats had been getting out there. So, the goats were defenseless. We now have 2 of our dogs in with the goats full time, and haven't lost another goat. I contacted the Tuttle police dept. and they too mentioned the mountain lion in Minco. The vet that we took our injured doe to said that it was something with a large bite that attacked, and not dogs or coyotes because there would have been bites to the leg area too if it were canines. Whatever it was, I figure it came through our creek area (we live a mile away from the S. Canadian river) and it jumped our fence that has the electric wire on top. I'll never leave our goats without several dogs protecting them again. Oh, and the Tuttle police officer sent me an email stating "While we do not have direct evidence of a mountain lion or cougar within the city limits of Tuttle, we have had sightings in the past. Also, a mountain lion was recently hit by a car in Minco. The wildlife department tells us that mountain lions can have a range of 100 miles or so, so the presence of one in Tuttle is a possibility."
I just hope that whatever it was decides to pick on only wildlife and not more domestic animals or people.
By the way, hello everyone! Sorry I don't get much opportunity to get online. I'm at work tonight and finally not busy. I wish I had more time at home with the critters. We finally started up our incubator and have mostly bourbon red turkey eggs in. So, if all goes well, Gerald and I will be at POOPS with turkey poults, and hatching eggs of all the varieties of birds we raise.
Oh, and we do have Komondor pups born on Thursday. Not sure how many yet. I tried to keep the momma dog in the house so she'd have them inside. She decided otherwise though. I let her outside to go to the bathroom, and she opened the gate to the barn, let 2 other dogs out, and then had the puppies under the barn. There's a crawl space under the barn, and Gerald was able to get near her, but not close enough to count pups.
