PetSafe Stubborn Dog Indoor Pet Barrier with Stubborn Dog Collar.
If your dog is over 20 pounds and is extremely stubborn or hard to train this is the one for you. The Stubborn Dog Collar has five levels of correction plus vibration in the warning tone as an added deterrent. It also has a low battery light to let you know when to replace the battery.

Adjust the range of the Indoor Pet Barrier from as little as 2 feet to up to 10 feet. Your pet then wears the same collar that is used for PetSafe underground pet containment systems. When your pet gets near the signal a warning beep sounds on the collar. If he continues to approach the protected area, a mild correction is given. The PetSafe Indoor Pet Barrier can be used for as many pets as you have! Each pet needs to wear a collar which can be purchased separately.

The PetSafe Indoor Pet Barrier can be put anywhere, in a plant, next to the front door, hanging on a wall or in the coffee table drawer. Whether it is hanging, standing or laying your pet will not be able to dig in your plants, run out the front door when guests arrive or beg for food at the dinner table. No training and No installation, simply place the small transmitter in the areas you don't want your dog to be, put the collar on him and watch as he stays away from the protected areas. You can use as many collars and transmitters as you need.
