PetSafe Quick Snap Buckle Nylon Martingale Dog Collar

This large sized collar is nicely made but way bigger than advertised. When on the shortest adjusted length it measured 19.5" unchoked and 14" choked. On the longest adjusted length it measured 25.5" when unchoked and 20" choked. Our dog has a 13" neck so this would slide off when unchoked and wouldn't slow him down when fully choked on a walk. Chewy, however, was great on the refund and offered free shipping when we order the replacement which will be the next size down. Hope this helps someone when preparing to order this collar for their dog.

I am so happy I ordered this color. I have a pitbull mix (75 pounds) with an 18 inch neck. I decided to order the size large. Once I adjusted it to the smallest size that fits perfect for going on walks. I do not have collars on my dogs inside my home. This is just for walking.

Despite measuring twice, the S was too large for Pippa. The loop bagged down to her knees even with the collar on the tightest setting. Reordered an XS, which appeared to fit even thought the loop was still baggy. Pippa wore it under supervision for a few days and then promptly chewed off the loop while I was on a work call.

I ordered a Large that is supposed to fit neck size 13-20 inches. On the smallest setting, I can still fit my whole hand under the collar on my dog with a 17 inch neck. I also tried it on my bigger dog, who has a 19 inch neck, and I feel it is still too big. I feel like if she really wanted out of the collar, she would have no problem getting out. Luckily, I have never had a problem with them trying to escape their collars. In one picture, I am only holding the collar up to show its looseness. Another picture, I am holding the leash ring up to show how far I need to hold it to get it to fit like a normal collar.

I bought two collars: petite for my 10 lb Coton de Tulear, and a medium for my 4 month Standard Poodle (Spoo) pup. The petite fit my Coton, though I won’t need to use it much, just when highly excited in crowds she pulls on leash. The medium is way too big for my Spoo pup, though I measured following the directions. I need this collar for my Spoo. Disappointed.

My dog has a 19” neck so I bought the large even though other reviews say it runs large. Since she is on the bigger side, I was hoping it would be fine. She is able to wiggle out of the large collar when it is at its smallest setting.I would not recommend the large unless your dog’s neck is 20”+.

Collar itself is great quality however the sizing is way off. Ordered L based on the measurements provided in description since my sons pups neck is 16”, even on smallest adjustment which should be 13” the collar is way too big. Should’ve gotten M but now that’s out of stock of course. Recommend sizing down or be prepared to have to return it.

Leaving the recommendation box ticked and giving three stars because, if you get the sizing right, it is a great collar and has held up well against a strong puller. But the reason two stars are docked is because their measurement guide is very confusing. I measured my dog as indicated at the top part of her neck and since both the medium and the large covered her neck diameter, I ordered the large so that she could continue to grow into it (she's 6 months old). The large arrived and the collar is unfortunately extremely large for her and barely hugs the base of her neck when the martingale section is pulled tight, so I can't use it without risking her backing out of the collar when it is relaxed Leaving the recommendation box ticked and giving three stars because, if you get the sizing right, it is a great collar and has held up well against a strong puller.

I would suggest ordering the smallest size possible that incorporates your dog's neck measurement and be prepared to re-order another size. … more

i really like these exept buyer be ware the 14 to 20 is huge on the smallest i can go is still too big even tho my dog with fabric tape measures 14 inches wish i would have bought the size smaller

I measured my dogs neck as instructed and even with the collar on its smallest size I could still slip it off with ease. It’s made well and is good looking but too big.
