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 believe the small size is best for this medium size is quite large, I wear 38 in Brazil !!

I would recommend a large based on how the size I bought ran. Hope this helps.

I looked on Speedo website and they list the following: Swim vest: Medium is for year 2-4 with chest 22" and weight 33-45#. Large is for year 4-6 with chest 24" and weight 45-60#.

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

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

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.

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 am a size 34, I bought a medium, and I have to squeeze into it. I would say large

Medium Large would give a very snug fit, extra large for a more comfortable fit

Depends on what is comfortable to you.I tried all three sizes and was happy with the medium size.

I have a 40 inch waist and the large is big on me so if I were you I would go with the medium.

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

Small, medium and Large. Difficult to choose the proper size. Your on your own. They do help.

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