Review on Patroaint Waterproof Dog Training Collar - Three Training Modes, Extended Range up to 2600Ft by Brittany Smith

I was skeptical about using this collar for training, but while it worked, I liked the dogs' response to beeps and vibrations. However, the actual collar never held the mechanism in place, and the dog's reaction only worked when the collar was tightened - the collar slipped non-stop. Unfortunately, after only three weeks of use, one of these collars broke down and electrocuted one of my Cane Corso. permanently until I remove it. All night he trembled and urinated with fear. I will no longer use them and will ask for a full refund.
