Our dog now stays in the yard.  after only two days she learned her boundaries.  For about a week she would barely leave the porch after the initial shocks but now she is over that and runs around the yard but not out of it. I could probably remove the collar now and she wouldn't leave the area.  Great system.

My 60lb retriever/pit hates this thing, but I love it. I have bribed him to allow us to put it on him with a doggy cookie each time I put it on. It does not appear to hurt or bother him, he just doesn't like having something on his muzzle. He does not pull and I have a much better time both walking and controlling him with this head-lead. I went from being the walkee to the walker.

Worked great on my Husky/Samoyed mix. I'm a petite person with a big dog. It took him a bit to get use to it. Felt bad when I heard him yelp the first couple times, but after seeing the end result, it was worth it. After a few training session, he responded to just the beep. Now, It has been years since and he's doing great without it. Please use with care though.

I have an extremely athletic German Shepherd/Belgian Malinois/Labrador mix and he's a puller when I walk him.  I have tried at least three different harnesses and he will pull despite his hair rubbing off at his chest.  The Gentle Leader is the only thing so far that has actually worked and has successfully stopped him from yanking on the leash with minimal effort.  I have significantly better control and don't worry about him being able to jump on people anymore.  There are only a few things I slightly dislike about the head collar.  For one, it leaves a little marking where it goes over his snout (I even tried loosening it).  Secondly, my dog doesn't seem to like wearing it... at all.  He paws at it frequently trying to take it off.  And he still scratches at his face for a bit after it's taken off. Lastly, the part that hangs down is a bit too long in my opinion.  His leash has a tendency to go under his body unless I keep the leash short.  These are only slight annoyances, and very much worth the control I have with him now while walking/jogging with him.  The Gentle Leader is highly recommended in my books.

I love it. My bully breed hates it, but she rarely pulls now. Not sure why, but I can walk with slack in the leash until it is almost dragging the ground with this on her, and she minds now. She can get this off, if you let her, but once you start walking, she seems to get over the need to snatch this off her face. Before, walking was like dragging a small bulldozer down the street, her choking herself and wheezing the entire time. Now she looks and seems civilized. And the pink color really pops. So cute.

Works great. Amazing really. We use this along with a martingale collar for my well behaved but powerful puller of a dog. Harley is a 140 lb. German Shepard that loves to pull and has easily defeated other anti pull harnesses. He will now stop immediately at the slightest tug of this leash. The only negative is the leash does not come in an extra long for very large dogs. Since Harley is so big, it takes much of the leash just to wrap around him. If it came 24 inches longer at this price point it would be perfect.

We recently rescued a 50-lb pit/lab mix. She's sweet and well trained, but taking her for walks was tiresome and stressful because she pulled so much, enough to cause her to rasp while breathing. While researching different types of collars and harnesses, I came across Gentle Leader. It seemed well-reviewed, so we gave it a try. We followed the advice to feed her treats through the nose loop so she would put her own nose through and that seemed to help. The first day or two, she resisted a little and while walking on grass, she would try to scrape the nose loop off. She learned very quickly, within a few minutes, that she could no longer pull or dash off, however - instantly making the walks more enjoyable. After a couple of days, when we told her we were going for a walk and grabbed the leash and Gentle Leader collar, she would eagerly put her own nose through the loop, her excitement to be out and about overriding her dislike of the loop. Now we go on multi-mile walks and they are a pleasure. I don't have to worry about pulling her back all the time, potentially injuring her. Sometimes when she sees a squirrel or deer, she will make a break, but quickly stops as the collar does its job. After a couple of weeks of use, she accepts the collar without argument or fuss, although she still doesn't like it. When we get home and take it off, she will roll around and rub her nose on the carpet for a few seconds, but that's okay - we don't see any sign of irritation from the collar - she's just trying to get rid of the "feel" of the loop. One side-effect, and some reviewers have mentioned this, is that other people seem somewhat wary when they see her with the nose loop because they think it's a muzzle and therefore the dog must be dangerous. The nose loop, however, does not inhibit the mouth opening or closing at all, it just looks like it might be a muzzle. For us it worked great and I don't hesitate recommending it to others.

This was the cure for my big mouth dog. She has to go nuts if there is any movement within her sight , and sometimes even if there isn't. The first time I put this on her I just waited and watched out at the backyard. A few minutes later someone walked by and sure enough , the dog started running her mouth. She kind of yiped once and was confused about what happened. So a couple seconds later she started barking again and yiped again. She figured out what was going on after that second time. She came back and laid down on the deck and was peaceful and relaxed and was able to just enjoy the time outside. I joke to my wife that the dog will add years to her life because she can just relax outside and not get so worked up and go bananas about every little thing and bark non stop for no reason. We don't use this all the time but there are some days when she seems more mouthy than others and that's when we put it on her. She has learned not to bark when the collar is on to the point that when we put it on her we rarely need to even turn it on anymore. I like that the battery is rechargeable.

Neighbors have commented and everyone that walks their dog by our house is in relief.  We bought a Havanese dog because they are not supposed to be big barking dogs.  Well, we got one that barks...and barks...and barks when someone walks by.  We hung this in our front tree and within a few days the barking had gone from 5 - 10 minutes of straight barking to 3 or 4 barks.  I hung it at about 4 feet high in a small tree that faces our entire front yard.  At first I hung it in a tree in the middle of the yard but I think it only works in the area that it faces.  Our dog was scared of it at first and wouldn't even go near the area that is was hanging but now he is fine and only barks a few barks. What a relief because I was really regretting our purchase of a dog with all the barking he did.  We also put up cardboard panels in our sidelights of the front door because he sits inside and barks out those whenever someone walks by.  It has solved that problem.  We're almost bark freeeeee!

5/30/13 - update.  This did work for a few months.  We went on vacation and had someone watch our dog.  When we returned it no longer worked for our dog.  I thought maybe something had happened to it so I got another one and it didn't work either.  I think our dog just got used to it.  We now have a collar that sends a mist of citronella when he barks.  It is at www.premier.com.  It's called the gentle spray collar.  This collar has worked for over a year now.  We only put it on when we send him outside but if we forget to put it on he'll bark his head off right away again.

My dog (8-yr-old, 30 lb, shaggy hair) rarely barks at home, but when camping or staying at a cabin by the lake, he decided he needed to defend me against all comers, including squirrels, etc. The collar is easy to assemble (insert battery, slide strap through, screw in electrodes). It comes with a tester device, so you can see if it is working. Once it is adjusted to size, you can easily clip it on or off, if you plan to use it only in certain situations. The only way to turn it off is to remove the battery, which is easily done. At first it was going off just from the dog shaking his head (I could hear the tone). I decreased the sensitivity and was fine thereafter. He figured it out right away and reduced his barking to one time. He would hear the tone and stop. He was much, much happier after that because he was no longer receiving constant disapproval because of the barking.

This is the second of these devices that I've owned.  The first was for a 7 month old boxer, and it worked as advertised - he went from a barking nightmare to a pretty calm dog.  After I returned him to his owner - who had been deployed - I gave the bark control device to him with his dog.  When I recently welcomed a 3 month old GSD into my home, I turned to this device to help with her barking.  It may just be her, as the other dog in the house is definitely effected by this device, but my GSD is immune...and may even be faintly amused by this bark control device.  I'd recommend seeing if a friend or family member has one and testing it on your dog first before buying it.

Wow! This thing works great! I have a 90lb rescue who had no training when I got him. And he's so excited to get out and explore the world, that he tends to drag me along behind him. But that's a no-no and a habit I knew I needed to break right away. So I bought this headcollar. I followed all the instructions and fortunately he seemed to adapt  to it right away. And it has made a world of difference. Our walks went from frustrating to fun! He's still able to sniff and explore, but now he has to do it with my permission. The good thing about me being the pack leader is that it's easier for me to keep him safe. He's a sweet, sweet pup, but as I always tell him, he makes very bad doggy decisions.  :)  I like the safety loop that attaches to the regular collar on the Halti headcollar&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/The-Company-of-Animals-Halti-Head-Collar-Black/dp/B004XNLCPC/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">The Company of Animals Halti Head Collar, Black</a>&nbsp;so I made something like it for this one. This would be 5-stars if it came with that.

Works great for our dog.  We like to feed multiple times a day instead of all at once and this really helps making things easier.  Most of the time someone is home so we see it in action and it functions perfectly.  Dog got used to it very quickly and has no problem eating from it.  She can hear the food being dispensed and heads over right away without the recording.

Awesome. This has been a godsend for my dog with separation anxiety. The first week, she wasn't into it at all. I would get all excited when it dinged and then I'd roll it around so she could have treats, but she wasn't getting it. Then after a week or so, it clicked. Now she loves it. I set it for the 90 minutes setting when I go to school and when I come home it's usually almost empty. I think it has slowly taught her that being away from me is a little nice. I never have it going when I'm home so she can associate the fun treats with being alone. I like that I can just fill it with her dog food which is more healthy than treats. I just feed her less on the days that I'll be away.

Also it is very durable. I have had it for about 4 months and my dog still hasn't realized that she just has to roll it. Instead she picks it up and drops it over and over like she's bowling. Sometimes she brings it up on the couch and repeatedly pushes it off. I guess my only suggestion would be to put a rubber coating on the outside so it's a little less noisy on hard floors. Or maybe my dog is just weird.

This made my dog a better dog. She had gotten a bit arrogant and uncontrollable. I put this on her collar and have only had to use the vibration setting. This setting is very unnerving to her and she immediately stops what she is doing.  She is a little more humble now and minds her mommy! :-) I highly recommend but only to good dog owners who would avoid using the shock until absolutely necessary because sometimes it just is.

I recently got a different bark collar for for my pets and found that I could not use it on two of my dogs because it was strong for them. There was no way to adjust the sensitivity on it. This Epic Pet bark control collar was described as being adjustable so I decided to try it. I am glad I did.

My rescue dog is a half pit/half weimaraner. She was abused and it took her years to learn to trust us. She is an amazing dog that we love dearly. The only issue is she barks at everything that moves. We thought for the longest time it was a learned behavior and was linked to her abuse. But our vet suggested it was merely an established habit that we might be able to break. Shock collars are not my favorite way to control a dog. But scolding repeatedly is no good either. I was truly hoping this collar would help her. She allowed me to put it on her without issue. She does not wear a collar 24/7 as she has issues with things on her neck. Thankfully, this collar is very lightweight. She has short hair so I did not need to use longer prongs. The first shock scared her. And me. Each time I would comfort her after. This went on for 8 days. Each day she would bark less. By the 9th day, I could leave my door open and she would not bark at the squirrels or rabbits. She still barked at my mailman, but I am okay with that.

I hate to make this long but want to add what we were advised to do. I do not leave this on my dog around the clock. While we were training her with it, we picked a code word to use with her. I would place the collar on her while she was barking. I would use the key word in a stern voice. Immediately after, she would get the shock. This has enabled me to be able to use that word WITHOUT the collar on her. I am hoping this is permanent. If not, we will place the collar back on her.

Adjusting the sensitivity is easily achieved on the control box itself. We have never had to go higher than the lowest level. But if we had a larger, or more stubborn dog, the higher levels would be great for them.

I received a sample in exchange for an honest review of the product. I am selective in what I test and review, and I will always give an honest opinion.
