Bandanas: Measure your dog's neck for exact size. Generally, the guidlines for the clothes sizes apply with the bandana sizes as well.
Please see individual items for additional sizing information. I have been gradually adding notations of what size the featured dog is wearing as well as his/her weight so as to give you an idea of how an item might fit your dog in comparison to mine.
As will clothes for people, not all sizes fit everydog the same way. Please take into consideration the proportions of your dog (extra weight gain, pregnancy, etc.) If you are not sure what size to order, please do not hesitate to contact me.
