Designed to pair with the FieldTrainer 425S and compatible SportDOG systems, the SDR-AS Add-A-Dog Receiver Collar is built for field use where quick expansion matters. In practice, trainers add a second dog to a single training framework during upland drills, waterfowl retrieves, or field trials without modifying the main control setup. The receiver provides consistent signaling across dogs, helping maintain timing and cues in practical training sessions with stubborn dogs. For care, wipe probes and housing clean after muddy or wet sessions and inspect the contact points regularly to prevent uneven readings. Keep straps free of dirt and replace worn components as needed to preserve a secure fit during long retrieves or fast chases. The accessory is designed to withstand rugged field conditions and supports workflows common to working dog routines in upland and waterfowl contexts. Use with a properly sized strap and confirm the collar remains attached and functional before a training run. Focus remains on the work at hand during field training.
