Molly, my 8 month old BC mix, has been coming to the barn with me 3-5 days a week since we got her at 12 weeks. She comes with my elderly ACD mix, who is good around the horses, she barked at and chased them when young, but SHE got kicked and that set her straight.
Molly has been great for these last five months…she sticks around, comes when I call her, is quiet in the barn, stays out from under the horse’s feet, knows she’s not allowed in rings or paddocks, etc…
Suddenly, just today, she started barking at horses who were turned out and, once, at a pony coming back from a trail ride. Argh!! She ended up being tied up because she was causing trouble.
I can’t tell whether she’s trying to herd them or play with them, but the behavior is unacceptable.
It came on so suddenly. What is the best approach to train her out of this, so she can continue coming to the barn and being loose with the other dogs? Other than letting her get kicked, of course ;).
