I've purchased many dog collars and thy always seem to work the first month and then break. My dogs are inside dogs and very spoiled. They aren't getting out in the rain or mud, so there shouldn't be any reason for these collars to stop working. This brand has worked longer than a month now- so its safe to review it. No issues yet...

They work! My neighbors complained about my dogs, which are house dogs, barking when they go out. These collars keep animal control away.

These were super easy to set up, turn on, and get activated. I didn't like that the directions don't explicitly explain how to turn off the shock feature, but after I figured it out I was happy. Our house is much quieter already and the dogs respond to only the beep!! I will update if needed, we just started using these 3 days ago and they are on 12 hours a day, turned off at night, and it appears the batteries are keeping up!

I was initially a bit dubious about how effective this would be, but thought that for the price it was worth trying. Glad I did. Worked very quickly to reduce barking by my German Shepherd (who would previously bark loudly if anyone was on the phone - not helpful when you are on conference calls!). I am selective when I use it (happy for him to bark to e.g. announce visitors) so just put it on when I need him not to bark - and for that it has worked well. Wondered if the two prongs might be uncomfortable, but I have seen no sign at all that they bother him whilst wearing the collar. Based purely on my personal experience with my own dog ...

This collar has solved the problem of my dog barking outside at every person, car, and neighbor’s dog. It’s such a relief. I tried a few other options from Amazon and this one for a two-pack was the best price and works great. The battery lasts around 2 weeks at a time, which I can hardly believe! Another one I tried needed to be charged almost every day! Try this one, I don’t think you’ll be disappointed.

These collars worked as soon as I put them on 1) 10 lb. Chinese Crested Puff and #2) 35 lb Pitt mix. These little lovies were running across the deck barking at the squirrels especially annoying late at night when they thought they heard something. I don't leave them on all the time, just when they begin the behavior again. It seems to humble them but they don't relate this to me. I use the vibration on 2, and the shock on 0 for the Puff and low for the Pitt. I do recommend.
