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.

The mediums fit great. If not, you could always go to a large. But you don't want them too loose.

Medium or large will work. My dog has both and she is about the size of a beagle. It just depends on how you want it to fit.

X large worked fine for my husband. He is 6 feet tall with broad shoulders and a medium build. Hope that helps.

I'd go with the Medium. The collar stretches a little over time, and you have to tighten it periodically. I think eventually, the collar will be too big if you go with the Large.

I don't know about the medium but....on my large (i'm 5'9/195), I wear layers and have no problems at all. The large fits really big on me and I've worn: base layers for top/bottom (thermal/underarmor, fishing pants, socks pullover zip and rain jacket. Still....i've got manuverability. As I stated earlier, this is a larger size though. IMO, I think you'll be fine. I hope this helps.

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. But, I don't recommend this brand. Very cheaply made. I would go to your local sporting goods store and check them out there first.

My dog is about 70# (German Shepherd), and the large is perfect. You can tighten it down. But my dog is also still growing, so maybe medium would be okay.

I have a 40lb dog and the medium fits perfect and works perfect. Hope that helps.

This is a medium listing. If you're anything close to 6'0" go large. There are adjacent adjustment straps to tighten around the body for a better snug fit.

I would recommend a size Large; the Medium will be way too small; the Large was only very slightly large for a 5'4" 125 lb boy

It is a perfect fit for the medium. I don't remember how much bigger the large is but if its much bigger then it won't fit
