The Petsafe Fence is the best, most advanced dog fence on the market today. The PetSafe PRF-3004W Electric Dog Fence features the Ultra light Receiver. We recommend this dog fence if your dog is 5 pounds or over and trains easily. The Ultra light Receiver has one level of correction and does not have the low battery indicator light.

PRF-3004W Fence Features:

• Ideal for any size yard, even up to 10 acres
• Approximate Receiver Size: 1.3 ounces - 2 1/8 x 3/4 x 3/4 inches
• Audio break alarm and light on the transmitter warns you if the wire has been broken.
• Ideal for Small to Medium Dogs

• Safety features include: Digitally coded signal to prevent false activation. Only our transmitter can activate the receiver. Other brands' receivers can be activated by Televisions, cordless phones, garage door openers, etc. We use filters and coded signals to prevent this. Don't trust your pet's safety to anything but a PetSafe Containment System.
• Receiver Fail-Safe. If your pet gets trapped in the correction zone, the receiver will shut down after 20 seconds to prevent over correction
