Likely so, however, you can make average size polo wraps work. What I did for Jack was basically took the size of a pony wrap, measured it out on my wraps, and just cut that amount off. But of course, just buying the right size saves you the trouble, haha! Just throwing a suggestion out there.
Edit to add: Oops, I realized it sounded like I cut the length of the pony wrap off. I should have said the difference in length! Mine had just a little over a foot taken off.
