PetSafe Comfort-Fit Deluxe Little Dog Fence System
Designed specifically for small and toy breeds with a lightweight, ergonomic receiver collar that fits comfortably on smaller necks. Lower correction levels calibrated for sensitive small dogs. The underground fence option for the dog that other systems weren’t built for.
Underground fence with a collar sized specifically for small dogs — fits necks 6” to 16”
Standard underground fence receiver collars are built for dogs 8 lbs. and up with average to large neck sizes. The Comfort-Fit Little Dog Fence is the system for dogs that fall below that — toy breeds, small-breed mixes, and any dog with a neck too small to fit a standard receiver collar comfortably. The collar receiver is purpose-built for small dogs: 2.25” x 1” x 1”, 2.8 oz., molded directly onto a reflective collar strap that adjusts from 6 to 16 inches. There is no swapping receivers onto other straps — the receiver and strap are one unit, which keeps the profile low and the fit secure on a small neck.
The system works like any underground fence: you bury the wire along the boundary you define, the transmitter sends a signal through the loop, and the collar detects when your dog approaches the edge. Your dog gets a warning beep first. If he continues past the boundary, the collar delivers a static correction. Four adjustable correction levels plus a tone-only mode let you find the right setting for your dog’s temperament. The system includes 500 feet of wire covering up to ⅓ acre and is expandable to 25 acres with additional wire.
Note on the extra collar (PIG19-11042): The compatible add-on collar for this system has been flagged for phase-out by PetSafe. If you need to add a second dog, call us at 1 (800) 524-2428 to confirm current availability before ordering.
