We had a dog a couple years ago-and we learned the hard way. He was a rott-chow mix who seemed to do ok when he was a pup. The bigger he got, the more interested he became in my chickens. He managed to kill 7 of them one day when he got loose-half my flock at the time. He was gone the same day. Being the dog lover that my husband is (I am not because I love my chickens too much) , I let him adopt two more that needed homes-with the firm understanding that they be very securely locked up in their kennel when my chickens were out. That worked for a little while. Until the one dog kept finding ways to dig and chew its way out of the kennel. Each time, he went right for the coop. (beagle-mix) We reinforced the floors and the fencing a dozen times over, but it didn't matter what we did, that dog still managed to get out. Heck, my DH even had a name for the kennel: "Alcatraz", in other words, no escape. We spent a lot of time trying to train these dogs, but to no avail. Ever encounter a dog with no hope of being taught? They were both like that. What a headache it was. We now have over 60 chickens-most raised from babies-they are much-loved pets. I went to visit family for a couple of weeks, and came back yesterday. The dogs were no longer around. I was almost afraid to ask why. My DH said he didn't want to tell me because it would have ruined my trip. I felt my face go pale. Once again, the one dog had chewed a hole THROUGH THE FENCING, letting the other dog out too while DH was at work. I have several hens missing and 4 dead. The SSS came for the destructive dogs. I know, people on here will say it's their nature....well, not in all dogs, and certainly NOT around my chickens. I'm sorry, I know some people may be offended-that is not my intention. I just wanted to tell of the important lesson I learned. No matter how secure you think your dogs are from your chickens, they are NEVER as secure as you may think. Lesson learned! And my heart goes out to all of you who have had to learn the hard way like me-I'm truly sorry for your loss and know what you are going through.
