I've used Gentle Leader for years!

This collar works well for my dog.  I use it to prevent pulling on her necks hen I walk her, which is one of the reasons why it was designed. I have been using it for years.  Like anything new, there is a bit of an adjustment period for both dog and owner.  The collar comes with a CD that explains how to fasten it, and how to use it.  It is very easy, and the CD is short and to the point.  The only problem I have, if you want to call it one, is explaining that it is not a muzzle, and, no, my dog will not bite you.  I find my dog easier to control with the collar; I think it helps direct her without tugging.

This product is amazing!  It's like having a different dog, one who is trained all of the sudden.  My Border Collie girl was a rescue and although I have spent 9 months with her now, she was still impossible to walk, pulled, jerked, ran after squirrels, birds, rabbits, children, and was either ahead of me or behind me.  I have to say that I am totally in love with the Gentle Leader!  I did watch the training film and read everything I could.  I also followed the break-in period with her and did everything by the book.  It works!  She isn't crazy about it, but wears it and walks by me like a little doll now and it only took a day or two to get this result after I started taking her outside wearing it.  I have total control of her, (my shoulder is so thankful) and my walks with her are pleasant now and much more controlled.  I still let her get off track to sniff bunny trails and enjoy being outside, but she is very much the little lady and I am so grateful that this product is working.  She was wearing a huge harness, had a big old retractable leash, and a bark collar before to tame her aggressive behavior when she lunged at other animals.  All gone!  I am really a fan and would recommend this product 100%

LOVE the Gentle Leader! I was using a prong collar to stop my dog from pulling and wanted something gentler and not so much of an aversive. The Gentle Leader is not only gentler, but much more effective than the prong collar. Even with the prong, she still pulled; she doesn't pull at all with this!

We had been using the prong collar for our puppy.  Then the vet said that she prefers the "gentle leader".  So I looked it up and found the Holt walking collar as an alternative.  The strap that goes over the dog's snout has nice padding and a soft fabric - which the gentle leader doesn't have.
I did take the advice of another reviewer - get yourself ready for the walk first (it's winter, so I'm gearing up with coat, hat, gloves).  When you are ready to start walking, put the collar on the dog.  My dog did successfully get it off of her face a few times within the first 5-10 minutes of the walk.  After that though, it was like we'd been walking with this type of collar for months!  She picked it up very quickly. (I had also tightened the part that goes round the snout so it was harder to get off.)
As for performance of the product - it's amazing!  No pulling or jolting away from the human.  This is a much gentler way to control your dog on a walk!  I was skeptical of the vet when she said that people never go back once they try this method - she is 100% right!  I will never go back!  Five starts in every aspect!

My 70lb pitbull was a nightmare to take for walks/runs until I purchased the Gentle Leader.  While she is still capable of pulling, it is much easier for me to keep her in check now.
The only downside is that the nylon of the collar is fraying pretty badly after only about six months of use.

I have bought other products that were supposed to stop a dog from pulling and were nothing but a waste of money. My groomer told me to try this exact Gentle Leader and I am so glad I did! I viewed the dvd and have been amazed with the results. My standard poodle who pulled even harder than my Siberian husky is now a complete joy to walk! Also, I priced this at a well known pet store after I got it from Amazon....it was priced double the amount at the store. I will be getting another one from Amazon when another puppy arrives....very happy with this product!

I can honestly attest to the usefulness and effectiveness of this product.
After having used the same one for more than 12 months, it remains like new.
It is perfect for sprucing up almost every area of my household and
auto interior. Its long reach makes my cleaning chores less difficult.
This product is also great for the elderly and less physically active.
I can't say enough about how liberating Dr. Jiffy has proven to be!

This is a life saver if you have a dog that pulls! It is gentle and requires no action on the part of the owner because the dog quickly learns that pulling causes themselves slight discomfort. It does take some time to master putting this on your dog, but if you follow the guidelines and suggestions in the manual with patience, it will become second nature to both you and your dog. My pain reason for ordering the gentle leader was because it was dangerous for me to attempt to walk both my curious, high prey drive Labrador and have a baby in a stroller at the same time. My dog would yank so hard and she was so strong that I would have to choose to drop the leash so the stroller and baby wouldn't tip over in the struggle. This leader made a world of difference. I can now go for leisurely walks with both canine friend and baby!

Gentle Leader has made what was a terrible situation trying to walk my 7 year old female pitbull, into a great thing we both seem to look forward to.  Before she would just pull so much my arms were sore.  She also had the habit of seeing something, rabbit, cat, other dog, roadrunner, etc and taking off and just pulling out of my hands.  She now walks slowly, doesnt take off, stands quietly when i have to stop and just is a better dog.  The only problem I have had is the metal clasp that holds the lead that goes over her nose and under her chin was missing a part, (it looks like it has a stop thingy to make it stay in place and not become loose) well that part wasn't on the Headcollar when I bought it and I didn't know it was supposed to, so i didn't return it.  I bought another Gentle Leader for my male pitbull and it has the part.  His works great and doesnt slip.  I cant return hers I guess because i used if for a while until i figured out the part was missing, so I am going to sew the place and "stop" it so it cant slip.  If that doesnt work I will order a new one for her.  This is a great product otherwise and it works on both my pitbulls.  The male is almost 100 pounds and can pull your arms out of the socket, and he is the best boy on this.  I have even thought of trying to walk them both at the same time, but once i get the females Gentle leader repaired or replaced, I may give it a try...

Such a life saver. This is a must have. My husband and i have a chocolate lab that weighs 70 lb. He is full of energy and would pull us when we take him outside. I have arthritis and would dreed taking him out to go to the bathroom. The gentle leader works amazing! He can not pull and it is so much easier on my hands and arms

Love this product! We used to dread walking our golden retriever. She is so loving and enthusiastic and so physically powerful! That combination was too much for my small frame. But this gentle leader works like magic! I can lead her practically with one finger holding the leash! We had tried the shock collar and the collar with the prongs and this is much more humane and works better!!

I've been using Gentle Leaders for my dogs for years now.  They are wonderful for dogs that pull.  My German Shepherd has never really cared for the portion that goes over her nose and will paw at it.  Due to this, after four years I needed to replace her old one.  To my surprise the new ones are padded around the nose!!!  She now doesn't seem to mind the gentle leader now that it has padding around the nose!  I love this pink one; the color is so vibrant; even with many years of wear the bright color stays very well.  The only thing I'd say is the sizing isn't perfect so it may be good to go to your local pet store to try on a few to figure out what size you need before ordering.  My German Shepherd is about 65-70lbs and the medium is a perfect fit for her; the large would be much too big on her.  The sizing of course is a recommendation and different breeds will have different head sizing so weight of the dog may not correspond perfectly to a size for a Gentle Leader.  I highly recommend this product.

I started using Gentle Leader and then brought my dog to a trainer. She suggested the halti instead and both work but I like the Halti better for the following reasons:

1) Halti has a padded area for the nose part. This is more comfortable for dog and does not leave indentation as the gentle leader does.
2) Has a part where you can clip to the regular collar. In case your dog can pull out of it you can clip this to dog's collar so you don't end up just holding a leash with no dog
3) The nose section holds looser so that there is less chance to send wrong signal to your dog by keeping it tight.

Note: you need to know how to use this item as using it incorrectly will not solve the problem.

People say dog can chew through any of these products. That is not the products fault, you don't want these to be made too heavy or else your dog will never get the idea to keep loose leash.

The gentle leader is a necessity for me because my 70 lb dog will pull me without it. Just putting it on seems to calm her. She doesn't seem to mind wearing it, because she knows it means she's going for a walk. But it must be at least somewhat uncomfortable because she'll stop at patches of nice grass to rub her snout...

Love love LOVE the gentle leader. Cannot say enough good things about it. It works wonders on my puppies who love to pull. They both got used to it after a few days.

I have two German Shorthaired Pointers, one is 13 and one is 12.5. About two years ago, the 13 year old started showing signs of hip pain. He started not wanting to jump up, even when he got invited to lay on the bed (which is a most special occasion!) and would whine any time he had to crouch down (like when entering his crate). My vet gave me a sample of Glycoflex 3 and suggested we try it. It made a huge difference within a week. I have been giving it to both my dogs daily ever since, and recommend it to others. When Glycoflex Plus became available I bumped them up to that. I take them to the dog park daily and they run like they did when they were puppies. There is another German Shorthair that we see at the park who is the same age as my dogs, and his owner always marvels at how mobile and youthful my dogs seem compared to his. I credit the Glycoflex!

I purchased this gentle leader headcollar for my Great Dane.  She is just over a year old and I have had difficulties with her pulling like crazy when I walk her on the leash.  The front goes over her nose and mouth and may appear like it is a muzzle but that is definitely not what it is.  She can still open and close her mouth fine.  The leash gets hooked underneath her mouth and chin.  It works great because if she tries to pull when you are walking her, it pulls her head back to you.  When I first put it on her, it took a little bit for her to get used to it.  Once she realized that when I got the headcollar out it meant going for a walk, she was fine with it.  I have purchased the harnesses that the leash clips to in the front and they do not work when I am walking her.  It is impossible for me to take her for walks without this collar.  With the size and weight of her it is imperative that I have a head collar that I can control her with without her pulling on a leash.  I will never use any other type of head collar for my great dane after experiencing the difference with this one.
