DogtraYS600 Anti Bark Collar for Medium to Large Dogs, Adjustable 10 Intensity Levels, Vibration Warning, Low/High Stimulation, Waterproof, 2-Hour Quick Charge Rechargeable Battery, w/PetsTEK Clicker

This collar is not your average junk. This is the best bark collar I have experienced in 20 yrs of dog work. It does not adjust per barks but activates a single warning then a stim for the setting you select. Be sure they are on tight so that you get a good connection. Be sure you don't leave on more than 12 hrs in one position.

Worked a couple times and then doesn’t do anything. Dog barks like crazy… and to top it off, it caused an infection. Too loose and doesn’t work, to tight and it wears thru the skin…. 30 day return window??? SMELLS FISHY TOO ME…

The Dogstra ys600 is a Godsend!!! It works amazingly at a very low level and corrects the issue immediately. It's truly been amazing to correct the barking !!!

This is my third one I bought for each of my dogs. They learn quick and know not to bark when it's on them. Only have to set it on 2nd level for them. So times we forget to turn it on and they still won't bark just because it's on them.

Needed this as we were moving to a new barn and the dog was barking at new horses.Functionally it works great for its purpose, and stopped the dog barking.The only problem is that it triggers when the dog scratches itself (no loud noises or anything, just the movement of the collar).No idea how long its been happening, but I witnessed her today scratching herself and getting shocked. poor thing was pretty distressed.Apart from this, great at what its supposed to do. I'm just concerned its triggering only on the accelerometer and not that plus audio.

My dog was really stubborn and just learned to whine instead so when she did bark most of the time it would shock but it wasn't consistent. Battery life was pretty good and was the only collar we found strong enough for our dog (very large dog) to have ANY kind of response but make sure to take it off and let the area breath as if they bark a lot with it on can cause some irritation on the skin.

Love Dogtra YS600 - it works! I also have two of the 1900s black for my hunt test dogs

I originally purchased this unit for one of my dogs. He chewed up his previous collar so it was time for a new one. I figured why not try a new brand, as it appeared this one had a much wider collar and the unit itself was much bigger, I was hoping it would be more affective. Once my big dog gets going, his original collar didn't stop him. Only helped with the small random barks. Unfortunately, this unit didn't do anything for him. Like, I don't think it went off a single time. I followed the instructions to charge the unit before use. I tested it with the vibrate "test" function which worked. Instructions say to slowly ramp up the effectiveness as needed. Started at 1, them quickly moved to 3. Then 5 and eventually 10. Not a single response from him during any amount of barking. Tried this unit on both of my other dogs with the same ramp up process and nothing. Returned it as I assumed it was defective. New unit arrives, I charged it first, tested with the "test" function, all good so far. Deployed it on the big barky boy, nothing.... Tried on two other dogs nothing... Not sure how I received two units that didn't work, so long story short, the second one was returned. Off to find another brand.
