Query: Unnecessary and Inhumane

There is no reason on earth for this product to exist. Regardless on where one stands on the use of shock collars, invisible fencing, etc., teaching a down-stay to a dog is not rocket science. With this product, the dog is shocked when he ventures away from the bed. This in and of itself is unnecessary and inhumane. But add to that the fact that dogs associate things that happen concurrently, and you've got the makings of much bigger problems than a faulty "stay." The dog could easily be looking at, let's say, your child when he gets shocked, thus associating the two. This can set up a dangerous dynamic. Even if the dog is not looking at a particular person when receiving an electronic correction, this type of punishment could easily create fear or aggression issues. PLEASE consider simply training your dog instead of taking this seemingly easy way out. Training a solid down-stay is NOT very difficult, and you won't be risking creating much bigger problems.
