What are the size ranges for Medium and Large?

The large collar fits my 77lb TW Coonhound very well; plenty of room to spare. The medium collar fits both my 62lb BT Coonhound; and my 50lb little mix. Again, with plenty of room to spare.

I've bought a small for an adult. So I think a medium will definetely be to large, unless he is a big boy.

I don't know what size the medium runs but I wear a 12 and the large fit perfectly so I would try the medium

Medium regular will fit snug.. but you won't have a lot of room to tuck it in or wear layers underneath. Large may be the way to go.

I would say medium. Even if you get the large you can tighten it all around to make it work. Medium can fit up to 65-70 lbs.

I purchased the Large size and they fit perfect. I am a 40 waist/32 in-seam, the length is a little long but manageable. As for the medium size I am not sure.

I have the large and the small, not the medium size. I have given the dimensions for both of those on the site. I suspect the medium is somewhere in between. Sorry I don't have the dimensions you were requesting.

15.2 inches for the medium. They do come in small, medium and large. The dimensions are provided on Amazon if you scroll down the page.

i have a 17 inch calf and I bought the large which is fine, you might consider medium, not sure how sizes run.

I bought my 70 pound lab a large. But a medium or large should fit. You can adjust both.

Medium/large I believe. I am about 6 foot and weigh 155 and it's a tight fit.

My wife wears size 10 and we got large and they work great. I can't imagine there would be that much difference between the medium and large.

Medium is size '12-2' and Large is size '3-6'. If your child is size 7, you should buy Large.

I have a large -- it's more room than you'd need. I'd go with the medium, like Sergio says. :)
