The small says up to 14.9" whereas the medium says from 16.9" across the chest. My 3 year old Shih Tzu is 15.5" across the chest. What size?

Not sure, I have two Labs. One is 85 lbs the other is 90 lbs. The XL is just big enough with just a little adjustment left. I don't know if their measurement is based on full allowable adjustment or not, sorry, can't help.

My dog is a 7lb Shih Tzu and it fits her perfectly, it would probably be big enough for maybe up to 9-10lb as long as it doesn't have too big of a chest, most small dogs have smaller chests than Shih Tzu. It really calms her down during a storm, really pleased with mine, would recommend to everyone. Hope this helps.

I purchased the medium collar and it is 3 mm, so I would guess that the large would be 3.25 mm. I have a yellow Labrador and she is just now one year old & she weighs 80 pounds and she still wears the medium collar. Hope this helps.

Hi, I got mine the x-small, he was about 10 pounds and it fit perfectly. That being said, I think this product is a sham and did nothing for our dog.

I would check the size chart to be sure. Mine dog is about that size and I think I got a medium..I would check for you but we have misplaced it. The size chart was spot on. Good luck, it works really well.

I would highly recommend following the size chart especially in the chest region. However, the medium fits my 7 lb maltese and the small fits my 4 lb maltese. Hope that helps.

Medium. I bought medium for my Bichon Frise (14 lbs.) He managed to get out the collar. Small was a perfect fit. Corgis are slightly bigger, so medium will be a fit.

My dog weighs 16 pounds and the medium just fits. If you dog is longer than 15 inches from nape of neck to base of tail it will be too small.

I have a 20 lb dog, and the small works for him. He is slender in the body, and thick in the neck, so I bought the medium first, but had to return it.

I have a 15 pound Bichon, and I ordered a size 'small', which works well......but he is pretty short, so that may be why the small worked for him. And actually, it just fit...so probably a medium would give you more option for adjustment..

I see your dilemma. I have a dachshund. She has a 19 inch chest and she fits a medium. With an 1 1/2 inches to spare. I tried the large at smallest setting and it was too big.

I got a medium for my Siberian Husky when she was about 9-mth old, and now she is 1-yr old and about 45 pounds, I'm kinda regret getting the medium size now, because although the bag size is suitable but the strips at her chest has to be adjusted to the maximum length so that the bag is not too close to the neck.

they go by size of neck and chest. you must measure. X-Large 15.7"-neck 21 to 32" chestXX-Large 19" neck 26 to 39"chest I would guess XXlarge, but you'd be better off measuring. My 16 pound dog is snug in medium.

There should be size measurements on the box. It's more about the chest size. I have two Chihuahuas and they take different sizes because of their chest size.

That is the approximate length of my Bugg (Boston Terrier/Pug), and she has fit just fine in the Medium for years. I did buy her a large recently, so I could carry more things in with her (wallet, diabetes test kit, etc).

the small size is for dogs that have a chest size 17 in. to 21 in. and a weight of 15 to 25 lbs

We are having a size problem. I love the harness. I have a twenty pound Shih Tzu and the small is more than enough. I also ordered the medium and it is way too big. The small is also too big for the 10 pound Shih Tzu. Hope this helps.
