We have used the Hidden Dog Fence company for about 5 years. When they installed the fence, they were courteous and professional. The trainer was great and very patient with me and my dog. Since installation, we have contacted them as we have needed new batteries, flags put back up for service providers, and troubleshooting. They have always been patient and willing to help! Now that our dog of 13 years has passed away, we are planning on calling them back to train our new puppy. Would recommend this company!!!
