Our golden retriever is so good with this fence!!! We took the time to properly train him and it paid off. He's only 1 now and will stay in the yard even when another dog is coming down the sidewalk. The employees are very knowledgable about their product and have always answered any question we had. Make sure you follow the training guidelines and you shouldn't have any problem. If we move... I'll make sure to get another invisible fence!!!
