We purchased the groundskeeper system and are delighted to report it has been a success! We don’t have fences on our property and we’re having trouble with our 10 month old Labrador, “Tilly”, chasing us up the road which eventually leads to a highway. After a surprisingly short amount of training she is a very aware of the boundaries and doesn’t try to follow us off the property or wander away while we aren’t home. The communication with the company is excellent with someone always available to answer questions and give advice about set up and training. Highly recommended!
