I have a Shepherd, Patience. I also have two horses. When Patience is outside, she will bark nonstop at the horses. I have tried the pennies in a can. I have tried tellin her no bark and dumping water on her if she continues. I have tried a muzzle. I have tried walking up to her, holding her nose shut and saying enough. I have stood there with my arms folded looking up in the air. She doesn't even notice I'm there. She is so fixed on the horses (or whatever it is she's barking at at the time), she doesn't see or hear anything around her. When I walk up to her and close her mouth and pull her head up towards me to make eye contact, she will still have her eyes focused on the horses (or whatever else it might be). I have to put my face right in front of hers before she'll take her eyes off of them. Then as soon as I let go, she's right back at it. The horses have been here for two weeks and it has not let up at all. Is there something else I could try?
