Size Guide
Please note these are approximates only. There are a few exceptions to the rule, for example corgis and basset hounds would need a small due to their little legs. As bandanas slide over the collar, the bandana will fit the dog as long as it fits the collar. The only difference would be if the bandana is too small it will appear shorter on the dog, and if it is too large the sides may bunch up on the collar.
