Very good training collar for my dog. I use this when outside with my dog who is off the leash. I would buy another if needed.

I have a 6lb Yorkie. Fits him very well, as most are too deep for him to comfortably stick his head out without choking. Straps ARE NOT adjustable but it fit me, I'm 5'6", though it would be nice to adjust for different positions. Very breathable. Only reason I knocked off a star is because the liner is a soft plastic material, I wish it was more of a cotton/cloth for comfort for the pup.

This brand of harness is one of the few that has sizes for larger dogs like my border collie mix. Both the girth and neck straps are adjustable which makes a good fit more likely. This harness is the second one of this brand that we've used and the first has held up well. Accordingly, I highly recommend this harness as an alternative to the usual collar.

Do not like "pulling" my pup along by a neck collar. This makes it much easier to control her (boxer/pit mix) and more comfortable for her. Easy to put on and off and very secure. Also works great with the pet seat belt I got. It has stood up well, as others I tried with her she chewed up. Put it in the washer a couple times and comes out clean with no damage. Best of all she loves to wear it and hates when I take it off. Kinda of like those compression vest you can buy to help dogs when upset by thunder and such. Fortunately my pup should be able to stay with the XL as that is the largest size if have seen.

This is fantastic for small breeds.  I work long shifts sometimes and my dog recently had puppies and unpotty trained herself during the ordeal.  This keeps her from messing in the house and it also worked as a great isolation for her to heal after her spay.  I'm with other people that have left feedback about it not being strong enough for the typical large dog you'd put in this size kennel.  If they're well behaved this will do the job of keeping them in one place, but I think even a 75lb would work its way out if it really wanted out.  Works for my 4-12LB monsters.

Works well for larger breeds so they don't have to bend down to get the food out of a bowl on the floor. Our Pit Bull has arthritis and this is just what he needed. Also keeps our little dog from getting the food meant for our senior dog.

Just a good crate for your large dog. This is the largest I have found. My 8 month Rottweiler will have no problem growing in to it. I am not sure if it would accommodate Giant dogs.

This product is much better than the head collar I purchased years ago. This one comes with a DVD showing you very clearly how to size it to your pup. My only complaint is deciding what size to purchase was tough, and it looks like I'll probably need to get one size bigger has our golden grows, but oh well. I have the medium on my 5 month old golden. it fits fine with some room for growing.
Here are the sizes on the package:
Patite: under 5 lbs: tiny, toys, puppies
small: up to 25 lbs: beagles, jack russels, shelties
medium: 25-60 lbs. Dalmations, pointers, spaniels, sight hounds
large: 60-130 lbs. Danes, goldens, labs, rotties, shepherds
x-large: over 130 lbs. Giant breads, over sized or large headed dogs.

I purchased this for my 9 year old black Lab/Newfoundland mix.  He is not having issues currently, but I wanted to be prepared and also to get him used to having the harness on for times in the future.  I am not very tall (4 feet, 10 inches) and I was a little skeptical that I could use this with my dog but it works beautifully.  I tried it with Teddy in a variety of locations, both to see if it will work for us and to acclimate him to the feel of it.  It is soft but sturdy and seems to be really comfortable for him.  I love that it rolls up and snaps closed to a small package that I can carry anywhere.  Just to make sure it is very flexible for different needs, I had a really tall friend (6 feet, 6 inches) see if he can use this comfortably with Teddy, without having to bend too much or hurt his back.  It worked great for both of us.  I recommend having this on hand, because you just never know.  For now, I have put it in my car, just in case.

I haven't quite got it attached to our dogs neck yet, but he's warming up to it.  It is a very strong rubber/plastic type material and so far my very nervous guy has been letting me slip it over his face and getting the strap around his neck.  I like that it has the collar loop - which I will have to get a smaller (less thick) collar for - the loop appears to fit about an inch to inch and a half collar.  Not sure about the strap over the head - will be nice to use if you have to, but I can see where that would rub on the dogs face, which could rub fur off.  We only plan on using this for when we go to vet and he has to be muzzled.  Because of the harder material, I wouldn't recommend using this for any kind of long term type use.  I measured per the chart from the nose to eyes and made my purchase by that measurement, hoping it would be wide enough for his very large snout/big lips (he is a large American Bulldog/Boxer mix) and the size 5 was the size I chose.

What I really liked is the little bit of freedom he will have.  The vet has let me use one of their spare muzzles (size XL), but the cloth keep the mouth fully closed one they have is too small to smash his big lips in there and he fought and panicked the entire time trying to get it on (probably cause it wasn't a right fit).  Instead of having to try and slide something on a dog while keeping their mouth shut, this can slip over even while he is licking it.  I think this makes him less nervous and much more comfortable.  He may look like Silence of the Lambs when he's wearing it, but his comfort and helping him not be so afraid of putting it on is much more important to me.

The large fit perfectly on a 45lb golden mix.  She was a HUGE hit.  Key here is to have a dog that doesn't mind wearing it. I'm sure not all pups would that thrilled

We bought two of these for our mini dachshund who weighs about 10 pounds. It's definitely on the big side for him but it's also super comfortable. Sometimes another, much larger dog friend of ours will come curl up on it and it fits her too!

I bought it because it was inexpensive, and it has held up well so far, so I'm pleased with the price I paid.

Great product for large dogs. I have a 50 lb. Lab mix and should have gotten the smaller size but it is okay.  My dog has separation issues and was able to unlatch the top latch and squeeze out.

I got this larger dog collar for our dog to put on her if she outgrew the 18" collar.  I like these collars as they do not get tangled in the dog's hair (and she has a lot of hair!).  Got several colors just for fun.  This type of collar is really hard to find and I am  so glad Amazon carries them.

Really keeps its form. Would be great for big dogs.

awesome thing for big and small dogs! the dog is not choking him/herself and way more manageable.

Great combo for bigger dogs. Much better than just buying bowls as my dog was always flipping them over :/
