To get the correct size to fit your dog take their collar measurement and choose the closest to that size. Small =30-35cm Med = 40cm-48cm Large= 50cm - 60cm
For fluffier breeds you will want a larger bandana so that it sits over the floof as seen in the pictures of the male border collies with their big manes. If there is a print but not the size available listed below get in touch and I will see what fabric I have in stock. If you want a custom made size I can do this also. I do christmas bandanas closer to christmas time.
Please note that Swirly the black and white bandana is reversable.
