SportDOG SDR-AX-E Add-A-Dog Receiver Collar

Use the SportDOG SDR-AX-E Add-A-Dog receiver to replace the original collar receiver or add a dog to a compatible X-Series system. Check the full model code on your handheld transmitter and on the replacement receiver.

Which transmitters take the SDR-AX-E Add-A-Dog receiver?

The SportDOG X-Series manual lists SDR-AX-E as the original receiver model for SD-1225X-E and SD-1825X-E. See the matching SportTrainer 1825X SD-1825X-E.

Buy by exact transmitter code, because similar receiver names and a shared range label do not establish fit. Check for the X in the model code before using this fitment reference.

How the receiver works

The handheld transmitter sends the cue. Available responses and the number of receivers you can use depend on the transmitter and its programmed mode. A replacement collar needs a compatible transmitter and the pairing steps for that system.

Charging and pairing

The X-Series manual shows the 1225X/1825X receiver seated in its charging cradle. Align the contact points and check the indicator light as described in the guide. Use the matching procedure in the SportDOG X-Series operating guide. The same guide explains how to match a new receiver to the transmitter and how to set up multiple dogs.
