This is a size S. The photos of the dog wearing it are for reference, so it might be too small for a Shiba Inu. Suitable for small dogs and cats ♡ It would be super cute to put it on them when you go to eat hamburgers♪ I'm selling it because it was a little too big for my Chihuahua. I only put it on once, so there's no damage and it's clean♪ When shipping, I will separate it into top and bottom parts and compress it slightly for packaging.
