Do you have a PG-250 or RF-250 collar purchased from Canadian Tire or WalMart ? Ever wonder why your dog keeps getting out ?  Be aware this collar can allow a dog to easily escape the yard as it is not omni-directional. What does this mean? Well, at some angles, this collar cannot not pick up the fence signal at all from your buried wire and hence, allow the dog to cross without any correction? Why are they priced so low ?
We strongly recommend upgrading your collar for one that works reliably - UL275, RF275 or even the basic UL250.

The Stubborn Dog Super Receiver (RF-275M) is for the occasional hard-to-train dog and is compatible with all PetSafe™ brand underground dog fences and Radio Fence and Guardian Underground Pet Containment Systems.
Less than 1-2% of dogs need the Stubborn Dog receiver. It is three times more powerful than our regular receivers and is designed with these dogs in mind. Because of its size, this receiver should not be used for dogs weighing less than 30lbs minimum body weight.

NOTE: This unit is not compatible with the PetSafe Instant Fence Wireless Dog Fence

NOTE:  This unit has now replaced the older " Stubborn Dog " collar RF-204
