SportDOG Add-A-Dog Receiver Collar, SDR-A

The website description states "Can be used with any SportDOG...transmitters". It can only be used with SportDog model 1825 or 1225 transmitter.

Unless you have the SportDog model 1825 or 1225 transmitters you are out of luck.

as i wrote in my review of my original sportdog 1225, this company makes superior products. They are worth the money and have significantly contributed to my dog's quality of life by making his leash (which he HATED!) obsolete.

these collars are waterproof and submersible as they claim, they are built very well, and actually have the range they claim. I cant say that about any other collar system i have tried.
