Sitting in the living room last night, watching TV...about 11:15pm. Our LGD starts barking. At first, it's just kind of a normal bark, but then it changed and became much more...acute? I dunno the word, but I knew immediately that he was MAD. Went out the front door with one of my border collies. The gate to the barnyard (and the goats and chickens) is just to the left, so when I get past the vehicle in the driveway and can see the gate, I see a big boxer-type dog standing there. I knew my BC would jump it -- and probably lose -- so I tried to hurry her back in the house before she saw it. She turned, but the boxer dog walked out toward the driveway. She saw him and started to run after him, but I called her off.. Well I'll be danged if ANOTHER dog didn't come out from the area around the gate...A BIG A** ROTTWEILER. That was too much for the BC, and she gave chase. I was yelling like a madman, and she actually did nip at the rottie's hind end but luckily he picked up the pace instead of turning to snap her head off. I was about 99% sure they were my neighbor's dogs, so I got my BC back in the house and called the neighbor's dad (I don't have the neighbor's number..never met him..seems like a jerk). Dear ol' dad didn't seem particularly happy to be awoken at 11:30pm, but he's super nice and said he'd call his son.. Anyway...the cool thing is that our big LGD -- a Sarplaninac -- stood his ground at the gate with a big boxer and an even bigger rottie staring him in the face. When I stepped out, I honestly thought there was a truck coming up the road because I could hear some sort of low rumbling sound. Turns out, it was the LGD growling. When he growls, the ground shakes....I kid you not. If not for him, those dogs would almost certainly have been in the barnyard before I knew what was happening. So, here he is....Big Ivan. We're so blessed to have him. GOOD BOY!
