SportDOG SDR-AXS Add-A-Dog® Receiver Collar for SD-425XS - Stuborn Dog
Add a second dog to your FieldTrainer 425XS Stubborn Dog system
The SDR-AXS is the Add-A-Dog receiver collar specifically built for the FieldTrainer 425XS — SportDOG’s higher-output system designed for dogs that require a stronger correction range. The “S” designation matters here: while the SDR-AXF fits the same list of compatible systems, the SDR-AXS delivers the elevated stimulation range that matches the 425XS base unit. If your primary system is the 425XS and your second dog also needs that higher output, this is the correct collar.
Like all SportDOG Add-A-Dog collars, the SDR-AXS pairs to your existing transmitter in minutes, gives you independent control of each dog, and uses the same DryTek waterproof construction as the primary collar. Submersible to 25 feet, 2-hour charge, 40–60 hours per charge.
