We have the Innotek Contain and Train system for two dogs. We installed it ourselves with minimal effort (buried the line to allow a 1-acre area to play) and trained the dogs fairly quickly. We have older collars with the transmitters, and the battery needs to be replaced every now and then..the mailman lets me know when Oscar is creeping past his line boundary ;) We also got the remote trainer to take them on hikes and that worked well also. We have recommended this product to all lab owners..it is essential that they can get out to run. The only thing better would be a wooden fence so that other dogs can not get in to THEM. We are very happy with this product.

Pros: Keeps the dogs IN

Cons: Lets other dogs in too...
