With all PACDOG collar kits, we supply a Training Guide. In this guide, we recommend the Dummy Familiarisation Period i.e. familiarising your dog with the collar by fitting the PACDOG Collar on the dog, turned off, for at least 10 - 14 days, before you enter the active training phase. We supply a set of plastic dummy probes with the kit, however, if you would prefer not to have to change out the probes, then this dummy collar option is for you.
This medium/large dummy collar is just a weighted collar (weighs the same as a live collar) with no electronics, and plastic probes.
See
PACDOG Training Guide here for more information on the Dummy Familiarisation Period.
