What is the abrasive buckle for and the conductive silicone cap for

Does this collar offer the automatic bark deterrent feature while still allowing manual control for other behaviors?
Answer by ChewyOct 21, 2021
This training collar must be controlled by the remote. It does not have an automatic bark deterrent.

Is it waterproof?
Answer by ChewyOct 11, 2021
This collar is waterproof and suitable for training in rainy and snowy days.

It says waterproof, so If the dog is swimming, the collar will still work if needed correct?
Answer by ChewyDec 30, 2021
While this is designed to be waterproof, it is recommended by the manufacturer to take off the receiver when your dog is swimming.

This collar has already broke

It was the lowest price one and it has already stopped working. The collar doesn't shock anymore and so my pit bull has figured that out and is steadily paying less and less mind to the warning peep and vibrate. Pretty soon he will begin to disregard it completely.hes the most difficult dog I have ever had. So I am actually getting ready to purchase a higher priced one. I had good luck with the ones before that were considerably more expensive. The last two has been very cost and haven't lasted long. This one is the worst one. It didn't last a month. So chewy is great and have stood behind their other units completely and so I have complained about this. Everyone knows what happens when you by from the bottom shelf... lowest priced items. So don't buy this item. Chew more expensive units are better and they do stand behind their products. I should have known better than to buy the cheapest one.

It Works for us

We don't use the SHOCK part but is a great product. We do a lot of hiking and it keeps out pup with us and distracted when needed. He is learning his commands. And where I broke my leg with a leash this is what I feel more comfortable with

Poorly calibrated and visibly cheap

You certainly get what you pay for this one. I was starting to train my high-prey-drive terrier mix on a remote collar with a professional--she used a Dogtra--and I needed to buy one to practice drills and to have on hand. I thought I could get away with buying a cheaper one (I could not) but the quality of this collar/transmitter combo was shockingly (no pun intended) low. On the Dogtra, we were working with a level 6 to 8 stimulation as a baseline, and for high intensity situations, my dog might be moved up to a 12, 16, 18 or so (out of 100) to compete with the tenacity of his interest in what he wanted to chase. At a 6 or 8, it was slightly difficult to discern if my dog felt the stimulation, which is what we wanted: a tiny flicker of a sensation that hovered right above his calm, baseline energy. At 12 or 16 or 18, he was noticeably feeling something but still sometimes choosing to ignore the stimulation for something scrumptiously fun like chasing. On the Petdiary, I tried to replicate our training procedure, and started my dog at a 2 (out of 100) and my dog winced and yelped. What exactly is 100, then? Maybe this collar isn't for people who are trying to train their dogs with collars and just want to use them for punishment? I have no idea, but I'm going to return this one and make the investment I should have made in the first place.

Not for the stubborn

Let me start by saying this won't work for a stubborn dog . My American bully pup of 10 months started to show some aggressive signs towards my older dog and started to not listen . We were awaiting her vet appointment to get spayed and needed an alternative until then so figured try a corrective collar. Started out on beep mode nice loud beep would distract her for a second. Tried the vibration and shock on low didn't even phase her now mind you I tried this on myself to make sure it was working on 1 . Not sure if the problem was if you follow the video and instructions it tells you make sure to be able to slip 2 fingers in between the collar and dogs neck . I find that was to loose and wasn't making enough contact. The tighter the better. But after tightening it up is she went into defense or aggressive morde it didn't phase her. We have shelved the collar and went with spay and a dog trainer.

Ok but one coller is broken after 1 use

These are OK. I bought 3 of the. After 1 use 1 of the clips on the collar is broken and is no longer usable.

Not successful

This only works for my bernadoodle if he is standing next to me. Obviously, useless. It doesn't stay on (his piece). I have charged it a few times thinking thats the issue but it is not.

Lasted a week

Initially, the shock on level 1 was way too strong. Put it on your arm and it would make your muscles twitch. Have to be careful not to accidentally turn it up in your pocket bc I dont want to know what level 100 would feel like. Luckily, my dog responded to the beep and vibrate for a while, but then began to ignore it. Then I noticed that the shock strength became lower, so I was able to turn it up and use it. About 20min later, and when I needed it to stop my dog from growling at a dog, it completely stopped working. It lasted a week. Besides that, there's no adjustability for vibrate strength even though there's buttons for it. So even if it worked longer than a week, it wasn't going to be very useful for long as my dog began ignoring it and the shock was insane.

Good collar

The collar is a little thin but it is for a smaller dog so that works fine. Easy to put on and off and the dog is taking life much more seriously now.
