I would advise anyone that is looking to have an invisible fence installed to avoid this company. I had researched numerous companies and decided to go with DogWatch. Big Mistake. Let me start by saying that the training manual, as posted on their website, stated that the training occurs in 4 phases. The first phase is supposed to consist of "audibles" only. The point of this first phase is to orient the dog to the boundaries and teach the dog not to approach the flags by means of a beep. The instructions clearly state that you should NOT move on to Phase 2 for AT LEAST 2 DAYS. Phase 2 consists of the introduction of corrections which the dog will receive if he crosses the boundary. Well our "trainer" Dave decided to condense the two phases. Within and hour of putting up the flags, he introduced corrections to my dog. There WAS NO PHASE ONE. How could a dog possibly understand what he is doing wrong if you haven't taken the time to introduce him to the boundaries and let him know he is not supposed to cross them?? My dog was so upset (understandably so) that she would not leave the house for days, not even to relieve herself. We ended up pulling out the flags and informing DogWatch that we want the system removed. What Dave did to my dog was a total disgrace! I have spoken with others who have had invisible fences installed by other companies and they were all pleased with the results. Unlike Dave, they actually followed protocol and trained the dog properly. I was livid with this guy and contacted the main headquarters to file a complaint. Their reply was "the trainer is permitted to modify the training as he sees fit". They were not bothered by the fact that Dave took what should have been 7 days of training and rushed it into one hour. It is now a few weeks later and if my dog sees a collar that even slightly resembles the one used during her training, she shakes like a leaf. There is no hope of ever having an invisible fence installed by another company because Dave traumatized my dog so badly. In addition, this company does NOT reimburse your money if you are dissatisfied, they will only reimburse a portion of it. We paid 1200.00 for our system and only had 700.00 of that money refunded. They fail to tell you that you purchase the wires and therefore that is not refundable. I truly believe that if you find the right company, an invisible fence can be a great product, but this company is NOT the right company. Shame on them and shame on Dave. (When I looked on their website today, I see that the training manual is no longer available for viewing. However, I have a hard copy of the manual which I had printed out.) read more
