I have a pitbull and the size large collar fits him perfectly! The design is nice and it’s super reflective, which is helpful at night. I don’t have any of the issues that other people have had with it being too slippery, but that might be because my dog is a senior and doesn’t pull as much anymore. Overall, a great collar for a good price!

I like the reflection and the D ring for leashes and smaller loop for tags. Also seems to be of really sturdy construction. Has become rather annoying though because I cinch it up to fit my dog's neck size and it keeps getting loose to dangle around her neck.

Fit well and was nice quality. Love that there is a little place on the side to put the dog license. And it doesn't hang in front either. I was very pleased with this product and at a good price!

Good size, seems sturdy. We have had it for several months now and no fraying or issues to this point with a rough and tumble dog

This is a slide over the head collar. No clasp. It fits over my boxer’s head just fine. If she pulls on the leash, the collar tightens. Reflective material is great too.

I really liked the look of these and they are strong but, at least on my dogs who play rough a lot, the collar doesn't stay the right size. It slips along the reflective coating, steadily getting larger, until they remove it themselves, major problem. Can't recommend unless your dogs collar is just for show, but you probably would not be buying a martingale style then. Look elsewhere.

What a great training collar !We are proud owners of a huge boxer name Hulk, he likes to chase squirrels, the reflective material makes it easy to see our dog at night the best part we finally have control over him.

It's a well made collar. Too bad I didn't get the color I ordered though. Would have given 5 stars if I had. May not provide enough comfort for dogs who have skin sensitivity or irritation.

It is very reflective. And it's solid. But it does slip, like a couple reviews mentioned. Works fine for me, cause my dog's too old for that back out of the collar move. But it's something to keep in mind, that if, at it's loosest, your dog can slip out when it's cinched, it'll happen.

The dogs enjoyed the product. It fits their necks nicely. And the reflector is great for nighttime walks. Thanks for attention.

It is reflective like I wanted. But I didn't realize that where you attach the leash cinches closed if the dog pulls at all. My puppy is getting choked everytime we go on a walk. I guess she will learn not to pull. But it wasn't what I expected when I purchased this collar.

The reflection is helping to see our dog at night. We feel safer now that she it wearing this daily with tags attached. The reflective material may become blurry or distorted over time.

Great study martingale Love the ring on the side for rabies/microchip tags Wish the 1in band came in a shorter circumference though. The large is definitely for a mastiff or corso.

This is not just for puppies. My dog is 10 and needed a new collar for when he's out walking. It's comfortable and perfect size. He's 43 pounds and we bought the medium collar. It's reflective and the price is right. I would recommend.

This collar is pretty. I will give it that. However, it does not stay tightened and the slip loop gets caught on anything they brush by. That can be quite dangerous in the woods. I would not recommend this collar for any active dog.

I love love this collar! The reflective part is so nice and I feel really good about my all black dog wearing this so she can be seen at night.

This collar is really nice. My dog has had it on day and night for over a month now and the strap stays in good shape. The the part that shines in the dark is bright and goes all the way around and has not cracked. The collar is adjustable so it can be larger as my dog grows.

So far I love this collar. I have 3 of these collars, one for each dog. Size medium has fit my 1 yr old Husky, 3 yr old Doberman and 6 yr old pit perfectly. The short leashes work very well too.

I was looking for a collar that has a soft interior for greyhound, to keep fur from being rubbed off. This was not what I was looking for.
