Our take on the BarkLess Pro BP-504 No Bark Dog Collar by E-Collar

The BarkLess Pro BP-504 is a bark collar from E-Collar Technologies that pairs tone and stimulation correction with adjustable sensitivity for barking, howling and whining. It offers a tone-only mode, eight manual stimulation levels and an auto mode that scales correction to barking intensity, plus a five-second safety delay and a waterproof, shock-resistant housing. It suits owners of dogs that bark heavily at home or in the yard who want fine control over correction level rather than a fixed-setting collar. Against simpler bark collars it gives more tuning and a rechargeable battery, but it costs more than basic tone-and-vibration units and still needs careful level setting for each dog.
