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 don't know what is the answer, but the medium size is fit to my son. He is 5 yrs old.

I would recommend a large. The medium would probably work until you got closer your goal.

I am between a medium and a large and large was way too big. So if you're on the edge I'd say go smaller.

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

I would probably go with the medium size, rather it be a little big than too small plus you can adjust it. Hope this helps.

I bought a large and a medium. The large is probably about the 9x10 that you want.

The small/medium should fit you well. Also, There is a lot of room for adjustment with velcro straps to get the right fit for you.

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'm a waist 32" about 160lbs, and a medium just fits me. Unless your under 150lbs go Large. Good luck.

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

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

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

I recommend you buy a package of each - medium and large. The medium fit me but I liked the large as it allowed easier application and gave some leaway for fit.
