Excellent Choice! Large Colorful Display ~ Adjustable Size ~ Works & Doesn’t Hurt My Dog & Fast Ship
I LOVE this bark collar! It is a really nice collar for my 17 month old Golden Retriever. He’s about 70 lbs now. It is a really nice quality collar. It has a large, colorful display that is easy to read and operate. It is size adjustable and intensity adjustable. It works great, offering gentle correction for him without hurting him! Lots of customizable settings and it really works. I live in an apartment with quiet hours so when my dog started barking, it was not acceptable. I wanted a solution that would not hurt him and this one is wonderful for that! It is gentle and effective-just gets his attention and redirects his behavior. If you are considering a bark collar that works and is kind to your pup…this is it. Also, it was delivered super fast after placing the order and was packaged compactly and nicely! Buy with confidence. Recommended! Thank you!

Customer Service
I had received the first collar and it failed 2 wks after purchase. It took a bit for customer service to reach out to me but they did. I must say, although it took a bit they most certainly made up for the wait. Ty customer service!Now allow me to get into the product. I literally love this collar. I’ve tried and own several other brands, a few that is Manuel for when I’m alert (awake) and home and for training, and a few for when I’m away or asleep. The reason for so many is because their battery life sucks, they’re far too weak or they don’t work as they claimed.The dogs I train must be obedient both when I’m away and when we’re out in public. I start off when they’re pups to make training easier as they age. This collar allows for several stages of the dog’s life, from pup, to ‘teenage’ (the stubborn stage) and adulthood. Just change the setting according to their weight, or bump it up if they’re more stubborn or have thick coats. Depending on your dog, if they respond to just the warning beep you can leave it there. You can have beep then vibrate or if stubborn, have all 3. The ‘ shock isn’t actually a shock, it’s more like a tens unit that we humans use to help ease pain but it sure gets the attention of your fur baby… and you choose what stage to set it at on. This collar made a world of a difference as one of my pups absolutely would not stop barking in my absence nor crying all night. Crate training is a must for the safety of my dogs and in my absence and the pup would not have it. This collar, nipped that negative behavior in the bud, quickly. I’d watch my cam when I was away to see if it continued to do its job and sure enough, she would start her whining, (I set it at 8) and before she could begin her constant barking again it stopped her in her track as she figured out, she gets the warning beep, and as soon as it vibrated, she knew what was next and stopped and chose to chew on her chew toys instead, lol. The dogs learn quickly the steps if they continue.I really like it because they get warnings before the ultimate tens starts and only took a few times before they understood their behavior was not appropriate.I raise and train German shepherds and anyone who’s raised them knows you can get a stubborn one or two in each litter and GSs are notorious for constant barking and growling if not trained properly. This is unacceptable behavior and this collar makes training them easy to stop it before it becomes a habit, especially with adolescents. I tested it with adult ones as well while I was away, took a day as the adults are more set in their ways, but sure enough, they got the message a well and stopped it. You never want to wait until a dog is full force barking before putting it on them. Their adrenaline is too high and not much will stop them at that point, especially in your absence. Just put it on them the beginning of the day or when you know what will trigger them and let the collar do the work for you. Make it a daily thing until they have it in their head automatically that the behavior will not be tolerated.I love the ease of the settings, the charging is quick and easy (a plus when raising and training several), and IMO, it’s the best anti bark collar out there yet!I believe my first one was a defective one and although it highly disappointed me as I thoroughly was impressed, customer service indeed made it right. I’ve got a replacement and I hope this one lasts as I have plan to purchase more for the others and as a backup, that’s how impressed with this that I am.So if you have a stubborn barker,growler or whiner, give it s try. What do you have to lose? Just familiarize yourself with it and set it according to their behavior and to what they respond to. It may take you a few days to get accustomed to it and to set it according to your dogs behavior and response, but don’t give up, it’s a training session for both you and your fur baby if you’re not used to using training or anti-bark collars. But when you do get it figured out to match your fur babies response mechanism, you won’t want to go without it!

It works, BUT not as smart as advertised…
This definitely helped train my dog to stop barking, but it also definitely has issues.What is GREAT: I’m not a fan of “zappy“ collars. The fact that I could remove the electrodes completely, and use only the tone and the buzzer is excellent. The interface is very easy to figure out, and also to understand with barely a glance. Sensitivity levels are easy to control and there are enough of them to match virtually any environment. It’s waterproof and scratch resistant. Battery life (while not using the shock function) is phenomenal.What is TERRIBLE: The “smart” functionality of this collar is almost useless. They advertise that it will “learn“ your dogs voice, so that it will not activate when in with other dogs that are barking. In reality, it can’t even figure out my own dogs voice. Initially it would buzz when he barked, but not when he would whimper or play growl. Then, overtime, it would start randomly triggering when he would whimper softly, or huff, and frequently not trigger when he would bark.Fortunately, my dog learns very, very quickly, and in the space of about a week and a half’s use, he has all but stopped barking. Based on my experience, however, I would caution that if you have a more stubborn dog, this may not ultimately be your best choice because you can’t depend on it to work consistently. The smart function definitely needs more work.It might be kind of cool if they could figure out a way to have a “training mode“ that doesn’t apply any correction but just listens to your dogs voice over time and learns it’s range. Then maybe apply filters to certain types of sounds so that the dog isn’t corrected for sounds that are not barking.
