The final straw was waking up at midnight to the screeching alpacas, crowing roosters, and howling coyotes. The whole "LGD" idea has been floating around my head for weeks now, and I have bobcats, coyotes, and even the occasional cougar or bear in the area. I'm especially worried about the alpacas, who are on the other side of the property. And even if there was something attacking any of my animals, it's not like I could do anything, either. I'd have to just sit there and watch... I have found surprisingly little information on guardian dogs and I'm not sure if it would be a good decision to get one. I have a relatively small amount of land (only 2.5 acres). I have no experience with dogs, but my dad has, so he could help. I would prefer to get an adult dog that is already trained. What breeds and how many would be best? Thoughts?
