Unfortunately - a sad tale today. Way to leave an impression on a new platform, right?...
I had the hens put up (or so I thought) and my Pyrenees went after two of them. I'm on another thread about dog attacks reading what others have said. Fortunately I have most of the stuff needed to do home care (saline, topical antibiotic, medical coop, etc).
The dog is in time out (photo is from when he was "a good dog," not today) and will be dealt with later by training or containment. My sweetie said the dog can be trained out of it. Here's hoping.
