This works pretty good.  My dog is smart enough to not bark when I put it on.  Hasn't trained her as I had hoped

Seems to work.  Our dog lets us brush the outside of his teeth pretty easily, but won't open his mouth wide enough to get the insides.  He's a rescue dog and insides were particularly discolored.  But, after using this powder for a few months, the teeth are much cleaner and his breath smells better.  We put a spoon of wet food in with his kibble and shake the powder on the wet food.  He gobbles it up, so it's very easy.  It's a good solution for a dog who won't eat any commercial dental treat.

I'm pretty happy with this. One thing that bothers me is that the material gets dirty and stiff from the dog's mouth as well as the ground because my dog is constantly rubbing her face on the ground because the leader is irritating (not painful or anything). The first few times she wore this, we noticed that it affected the coloring/markings on her face. I'm not kidding...she's a shepherd with a mostly black face but the leader rubbed the fur on her face and now it has turned into a tan marking (which is the undercoat color) in the shape of the straps of her leader. I know that sounds weird, but it's true, and I'm not the only one who noticed it.
It's easy to put it on and once my dog got used to it (it didn't take long), she sits calmly, waiting for me to put it on for our walk.
That being said, the leader is a godsend. It's the only way I can comfortably and confidently walk my dog (who's only 6 months old). So, I definitely recommend this to anyone who has a dog who pulls on the leash. I'm hoping it "trains" her into walking calmly without pulling, but I don't think it has had that effect yet. Time will tell.

This works great for my dog. He is really bad about pulling when on walks and with this he barely pulls now. Once it is on he doesn't really mind too much to have it on either.

We have a opening going from our living room to our kitchen.  We also have a very smart, but naughty dog.  There is a sofa on the same wall of this opening and the dog would use the sofa to get up and though the opening an onto our kitchen counters to get whatever he couldn't reach.  I had actually setup a camera to record this to confirm our suspicions.  I would have been angry if I could have stopped laughing.  Anyway, it's hard to correct the dog if he always does this while we're away.  I came across this product and though it would be worth a try.  It has been 100% effective.  I don't have the camera there anymore, but I can tell that things are safe on the counter again.  It has a blinking light that shows how many times it has been activated.  I don't feel I can trust this light so I don't know if it has been activated.  The mat it a bit bigger than the the sill of the opening.  I can, at times, touch the faucet on our sink and go off.  We've never be zapped by it, but I'm afraid that those show up as false alarms in the blink count.  We put something behind the faucet to shield it, but still and not 100% sure that fixes it all the time.  My best guess is that the problem is solved now and I could probably remove it.  I will probably do that and move this to another no-no area for the dog.  BTW, both me and my wife tried this before we set it up to make sure it was not too much.  We both felt the small zap was fine.  It is nothing I would describe as painful -- just uncomfortable.

works ! helps me control my dog a little better. she doesn't pull as much. The piece on the nose has foam on it so it is softer than others.

Works well, even after by other dog chewed it up a bit. My only concern is that my dog can go pretty much right up to the line before it starts beeping at him. Don't like that he can do that. All the other dogs can't get close to the line but he can just walk right up to it.

We have a beagle and she is sometimes too smart for her own good and strong headed. This product worked for a while but them she learn how to go around it. If is something that get her really excited she keeps barking regardless of the smell and wet face.  It seems as she knows it won't hurt here so she just ignore it. For most dogs and thing is a very good thing, for spoiled dogs is better get something else that reaffirms we are done with barking. We get another collar http://www.amazon.com/gp/product/B00LVUOYSW/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 and it is working better.

Works well. I have a 65 lb Pit bull pup who likes to run off and jump, so we use it for this. I personally don't like having him off the leash but when I did once- the beep & vibrate on highest setting didn't do anything. I was skeptical to use the shock so I just put him on the leash although I could tell he liked the freedom. He also is very smart and knows when the collar is on him to behave. My boyfriend said once he took off and he used the shock feature & he came right back. Almost to the highest setting though, anything under 75 doesnt phase him. Overall, the product works as described, the only reason I give 4 stars is the ugly plastic collar which you have to cut to adjust to neck size.

Pretty large for a 6 lb dog but it works. Note, he knows when he is not wearing it and will bark, so may not be a perfect training device. Caveat:  The dog is pretty smart::)

My dog has the habit of picking her kibble up and leaving it everywhere around the house without actually eating it. She's also not particularly good at puzzle games.

This thing wound up being an interesting solution to the problem -- the rope got chewed through within a week, but filling the bottle with her kibble  has made it so she only goes for it when she's hungry and therefore eats the few pieces that come out at a time. And it keeps her entertained, which is a big plus.

I have been using this device for about 2 weeks and it seems to perform quite well. My dog, a Sheltie, with a very strong herding instinct, is responding to a low setting of 2, but she is determined to keep herding people into and out of the house. If your outside she does not want you inside and once your inside she doesn'e want you to leave. It does not seem to hurt her in any way, all she does is stop barking and look around somewhat confused. I think she will learn sooner or later, she is just bullheaded. My only complaint is short battery life so if you buy this you might as well buy a lot of batteries from Amazon.

I was able to have my dog off leash within 1 day. she is a bit skittish and really pays attention to when the collar beeps I am hoping soon to shut off the correction aspect soon. I have a 20 lb dog and her setting is on 2. (stubborn) This works fabulous for not having a fence. I cannot speak to a larger breed dog but it works well for my small dog.

For the price this is a good bark deterrent. The battery did not last too long so order batteries with it. My dog is smart and it is working well!

Decent bark collar-- works fine except my dog has learned he can bark 2-3 times without consequences, and waits a while to do it again. I would like the option to skip the beep/no zap warnings and start the low-level zaps from the first bark. But maybe a dog shrink would tell me that's not ideal, since it's natural for dogs to want to bark at least once in a while, etc.
Good product.

Used with a ~20lb and a ~12lb dog. This leash works well for them. Though they can still twist it up if they do multiple crosses before it propagates up to the spindle, it cuts out maybe 80-90% of the tangles. When that happens you can just spin the spindle without having to manipulate the lines themselves.

The lines are a bit shorter than I'd expected but it makes sense. The leash would look like a comically large cartoon raygun if it doubled in size. Besides, if I'm using this then I'm alone so the dogs are easier to watch/handle if closer in.

The brake feels a little mushy unless locked (vs the buttons just pressed without the lock) but that doesn't bother me. It's always locked until we get to an open grassy area.

For my uses this was a good buy.

We have a deaf and near sighted dog who is too smart for his own good.  We got him this toy and it works well, but we had to cut the opening big enough so that his kibble would fall out pretty easily.  He likes the toy and it keeps him occupied pretty well, but he has a harder time solving it because of his disabilities.  He chews on it a lot though, and it's held up perfectly fine.  I would definitely recommend this to other smart dog owners who are looking for a solution to bored dogs!  The only reason it's not at 5 stars is because it's nearly impossible to clean thoroughly.
