PetSafe Martingale Dog Collar with Quick-Snap Buckle - Medium, 1 Inch, Red

It does not mention sizes in the description. So I guessed on a size. I ordered smalls which luckily fit my two shelties. Their neck sizes are 11" and 13". The size chart it came with says: petite (5"-8") small (8"-12") medium (10"-16") large (14"-20"). I'm just glad I ordered a small. Mediums would have been way too big. So when ordering order a size smaller than what the chart says. Hope that helps. :)

I love Martingale collars, and have purchased several over the years. Material wise this is a solid and affordable collar, but to echo other reviews, the size chart is quite misleading. I purchased a large for my 55 lb pitbull mix. His neck is about 16.5 inches, and the large is definitely too big. In the photo the collar is adjusted to it's smallest possible circumference, and I have my finger very loosely hooked underneath. Fortunately, I have another larger dog who can make use of it, otherwise I would have returned it. One feature of a martingale is that a dog is unable to back up out of the collar. I can't walk him with this collar because i think he just might be able to. I took off one star because an inaccurate size chart results in having to return and/or exchange an item purchased online for the express purpose of saving time. It's also not as though his neck size is on the cusp between a medium and large. According to the chart he's a large.

My crazy dog is the love of my life, only problem is she loves squirrels, hates public buses, and large trucks especially 16 wheelers. Unfortunately for me , she's a very strong 62 pound German Shepard/lab/pitbull hybrid. When any of these things come nearby she will pull and pull. We have even had various incidences including her leash popping right off from her tugging, and she's a part-time escape artist from any harness or normal collar.This collar saves my arms, and her life. After she ran into a busy intersection running from a 16 wheeler and scared me to death, I knew something had to change. I found this collar. My life and hers has become so much easier. She's still tries to pull and the collar GENTLY tightens and she relaxes. I can finally run with her without any worries. Squirrels don't stand a chance.My only wish is if it were a little thicker, for her anxiety. Going on three months and still no problems.Sizing:She's a medium size dog, 59-62 pounds. A medium works just fine for her.

There is WAY too much confusion about sizing on this item. Hopefully this helps!I bought my 40 lb AmStaff/Heeler mix a medium based on other reviews, which is too large. Here's the issue- the sizes the manufacturer gives don't include the extra length of the tension band! The tag that came with it gives these lengths: Petite 7-9", Small 9-11", Medium 11-15", Large 13-20". All wrong! The tension band on the medium adds another 3.5" when relaxed.My dog measures 13.5" directly behind her ears where a martingale is designed to sit, but even at the smallest size the collar will adjust to it's still 15.5" when there's no tension. This makes it large enough to slip off her head, or slide down to the base of her neck where tension correction chokes your dog. It also means you have to keep moving the collar to the correct position. Not safe!Martingales are designed to sit high and only use tension for quick corrections, otherwise you can injure or kill your dog. The reviews that say these collars can kill are right, but it's because they were being used irresponsibly; when ONLY used for walks and other leash training exercises- and fit properly- they're very safe and effective. They aren't meant to be worn without supervision! CAN I STRESS THAT ENOUGH?For the annoyance and lack of safety and sizing info on here this gets a lower rating, but the product is great, if you have the right size. My dog has her regular collar for tags and knows this collar is all business.

Our Goldendoodle measures 11" and at 5 months got the medium size which the sizing chart says its to be good for 10" - 16". IT'S TOO BIG!!! Thank goodness she'll grow bigger and this should fit properly in the coming months.Ordered a SMALL which should fit and perform it's job correctly.Would have given 5 stars if the size was right from the onset. Would rather use this martingale collar for this gentler breed. Our Rottweilers use choke chains (Made in Germany). Should've followed the advise of the other reviews that recommended to buy one size smaller. At "full pull" this size collar compresses to just a regular collar with still enough clearance for two fingers.With other future dogs to enter our household, no problem having different collar stock for future use. The positives are: strong plastic snap that most martingales don't have, quality vinyl straps, thick chromed metal rings. Will do another review once the Small arrives.Update:The Small arrived and fits snuggly with enough leeway to last for our dog's neck to grow another inch. Am so pleased, now that it's the right size, we ordered a second in purple to expand her wardrobe!!!UPDATE: The Small size arrived and the collar works as it should. With our standard sized Goldendoodle approaching 6 months old, this collar should be good til she's a year old, then the originally ordered Medium, should them be as effective. First pic is Medium, Second is Small wherein at "full pull" compression is felt with no space for any fingers. Wife wishes they would make a small in 1" as she finds the wider collar makes her dog cuter! I'm happy enough with the 3/4". Will look to get purple color for Xmas with a matching leash. Am getting a kick of giving the wife her doggie surprises. For the same amount of happiness she gets, it's way cheaper on my pocket than a handbag,clothes or shoes!!!!

Collar quality seems fine, but the way these collars are measured is all wrong. Most martingales are measured when not cinched, so as if they're regular collars. I have a dog with a 9" neck, so I bought a size small which is 9-11". But these measurements are when cinched. The length of this collar at its smallest size, when not cinched (so when it's just loosely on her for walking - as they should be, if a dog isn't pulling) is 12.5" - WAY too big for a 9" neck. If it's not cinched and she puts her head down, it just falls right off, at its tightest setting. A martingale should be measured as collar length, not cinched length. You buy a martingale to fit your dog's neck size as a regular collar does and the cinch is that extra bit of protection against a dog slipping out, when needed. So a 9-11" martingale should fit a 9-11" neck, then have the ability to tighten further when cinched. I bought 2 collars at the same time from different sellers, both size small, both 9-11". The other one fits exactly as its supposed to. Unfortunately now I have to return this one and order another of the other kind. Fortunately customer service seems ok and returns appear quick and easy, other than an unexpected and inconvenient trip to the post office. If you're buying one of these collars, BUY IT SMALLER THAN YOU THINK YOU WILL NEED because the sizes listed are cinched size, not actual collar size.

The safest collar you can buy. Kind to put on and she cannot escape unlike a normal collar. Always buy a martingale with the clip, its awful other versions ramming it over the poor dogs head, then the struggle to pull it off. BUY THIS ONE. Such a great price as well, great quality.

I got one of these for my little spaniel, much nicer than a chain type choke collar, just provides her with a bit of feedback if she pulls ahead. I've found it works really well

These are the best collars to use as they check your dog without getting to tight, and slacken off when dog is in the right position.

I have been pleased with this collar so far, I had a different brand and the material wasn’t nearly as sturdy. I bought this martingale for the buckle, my golden retriever has a very big head and the slip on collar was such a problem. They must be snug to work properly and this one you adjust once. The buckle is solid, clip is good as well. Always buy smaller than you think, my 84 lb retriever is using a medium. A large would probably be for very large breeds like mastiffs, Bernese and Newfies. It must be snug to work. Great price too!
