Works as described

I've had other collars that did not work at all. Received this collar and used right away. The tone/vibrate worked best no need to shock (so glad) and when we put this collar on, he knows we are working! Highly recommend My daughter got the 100 - we have huge fields around us, so the 300 is perfect.

We were having trouble training our bernedoodle puppy (closer to a year old). We tried classes at PetSmart and researching on YouTube. We were spending a lot of time on training and becoming frustrated with the lack of results. This collar was a game changer. Our dog is extremely obedient now. She usually responds to commands with just the audible beep and sometimes we use the vibrate to get her attention. We only have had to use the shock at the lowest setting a couple of times when we first got the collar. It isn’t animal cruelty and the shocks aren’t that bad. I tested all of the setting on my own arm when we first got it and they are not anything crazy. We don’t even put the collar on her all of the time and she is still very obedient. I wish the battery on the collar lasted a little longer, it only lasts about 3 days. Very happy with the product, its ease of use and the results it has produce.

It is helpful in teaching the livestock guardian dogs not to go after certain animals.
