Size listed should fit an average size dog of the breed listed. Sizing measurements provided are a range for the pet that will be wearing the costume, not measurements of the costume itself. For cats, one size fits most. Not all costumes are available in all sizes. Please refer to the individual product page for actual available sizes. We recommend that you buy one size larger if you are unsure of you pet’s length or if it is uniquely proportioned.
