Dogtra 1900S Ergonomic 3/4-Mile IPX9K Waterproof High-Output Remote Dog Training E-Collar with Teacher's Pet Complete Training Kit with Clicker, Stainless Steel Chain Lead and Hunting Dummy Bumper

My pet behaves better. Started with vibration then if she knows what to do she gets small nick.

Works on any dog breed

I had a heck of a time getting my Mastiff pup (almost 2) to come back, to potty outdoors, and stop jumping on people. I was unsure how a training collar would help but at the advice of friends I purchased this one, watched a few training videos. My little guy (ha!) immediately responded to the vibrate function, it got his attention. I began testing the shock levels as explained in the videos I watched, starting off at level 1 and moving up until it caught his attention.. He was very stubborn and even when I could visually see that he could indeed feel it he absolutely refused to look at me. Feeling like a monster I took the collar off to try again another day.It seemed to have done the trick though, he comes when called, no longer pulls on his leash, rarely jumps, and has had very few potty accidents. All in all I would recommend this collar. It came with all kinds of extra goodies which he absolutely loves!

Very fast and easy the best part is it files at the 45 degree angle which is recommended for dogs nail

Great product, great price. Nice extra training items included for the same price of just the unit.
