It's still long before I'm ready to keep my own horse, but I'm trying to plan as much as possible. One of my neighbors is a hoarder and has about 25 dogs contained in a small area on their property. These dogs are extremely unsocialized, untrained, and have no respect for people. The owners arent quite right in the head, and these dogs do occasionally get out. First time last Thanksgiving they got into the pen with my dogs and ended up costing us over $2,000 in vet bills. Early this summer three of them got out again and took out all 25 of my chickens. They came back the next morning and went after my rabbits, who luckly made enough noise to alert us. Running out trying to chase them away the lead dog actually came towards us growling - so out comes the gun and 2 out of 3 down. About a month ago the one that lived ended up back in our yard and took out over half of my replacement flock, and then just this morning I woke up and went outside to find my rabbit hutch torn open and my bunnies dead on the sidewalk.
The Sherriff is aware, however all but the time we killed the two do we actually have proof that it was their dogs (the second time they got my birds the owners did admit to their dog getting out again) so pressing charges is going to be tough, we are out of city limits so there are no number limits on dogs, and all their physical needs are being met so can get them for neglect. At this point I can't trust keeping anything unsupervised outside, these dogs have chased neighbors horses and taken out lambs.
I'm wondering how dangerous are dogs like these to horses in a smaller pasture/paddock where they may not be able to outrun them very well? How much damage can dogs do to horses trying to defend themselves?
