Sportdog no-bark collar
We have two dogs and they have taken to barking during the day. The curly retriever has taught the kelpie to chase and bark at birds. Since we received & fitted the collar to the curly, the barking has all but stopped. In another week or so I don't see the dogs barking at all. I would recommend this device to anyone who has a dog that annoys the neighbors by barking a lot.
