How do I choose the large size?

Choose the large size for a pet in the 21–29 lb (9.5–13.2 kg) range, and use the size chart and sizing video to help assess fit. Pet costumes run smaller than regular apparel, and breed alone is not a reliable way to choose because fit can vary between pets.

• Compare your pet’s weight with the large-size range.
• Use the size chart and sizing video before selecting a size.
• Do not choose by breed alone.

When can my pet wear this costume?
