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 have the large and my knee and 2' above are more in the order of 15.5" and 18". I definitely would get the Medium.

I would say a medium or large. I have an xtra large for my Saint Bernard and that would be too large for your needs.

Small size is 17.5 cm and Large size is 20.5 cm. Go for the Medium! It's 19 cm.

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

My son is a big guy about 6ft 2 and the large was great and plenty of room for adjustment. If you are average body with shoulders not too small I would get the medium and adjust it.

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 would think the medium would be your best bet. If you like a looser fit go with large .Made very well for the price .

Size Large fits my 120 lb Newfie and would easily fit a larger dog; I think a size Medium would be okay for a 75 lb dog.

medium / medium. There's a sizing chart somewhere. Most likely found on the manufacturer's website. Start your research there.

I would definitely go with medium. These are very tight. I was barely in the large range and there would be no way to get into the smaller ones for me.
