Expand your Dogtra Edge RT Remote Training System with the Edge RT Additional Collar. The Dogtra Edge RT system can be expanded to control up to 3 dogs at once. Due to the size of the collar module, we only recommend this receiver collar for dogs above 15kg.
Caution: Do not touch the contact points on the receiver/collar when code setting the EDGE RT. If you do so, you may receive a static electric stimulation. Also, do not attempt to code set the device while the receiver/collar is in contact with dogs, other animals.
