This includes the Off-Leash K9 Training E-Collar which all of our dogs are trained on, a 15 foot leash, and includes all FOUR lessons. So you save by paying for everything up-front! The e-collar we use has a two-year warranty, it is completely waterproof, and it has a range of 1/2 mile! This will be brought to your first lesson along with the 15-foot leash! By the end of this package, your dog will be able to be outside, off-leash, with distractions listening on command.
