Review on 🐶 Professional Grade Waterproof Remote Dog Training E-Collar with LED Receiver - Dogtra Edge Long Range High-Output 4-Dog Expandable System (1-Mile Range) by Missy Carter

Great for my English Mastiff. I had to drill additional holes in the straps to fit the huge neck. This works great when I need to take him to the vet or in public when other people and dogs are around. Since he is a gentle giant and likes to meet and greet everyone to make friends, I had time to hold him back. He wears the collar in the water when we go camping, the collar must have gotten him wet and gradually stopped working. I called Dogtra and they asked me to fill out the paperwork and send the collar in for revision. A week later I received that the collar is working properly. The lighting feature is very good at night, allowing you to track and see where your buddy is. I have 3 dogs so I bought 2 more collars to match the receiver. Programming is easy and the color of the buttons on the controller matches the color of the collar. I haven't had any problems with the other two collars, I've had them for a year now.
