How do I choose the right size for my pet?

Choose medium for a pet weighing 11–20 lb (5–9 kg), and use the size chart and sizing video when deciding. Rubies costumes run smaller than regular apparel, so apparel size alone is not a reliable guide; fit can also vary between pets of the same breed.

• Compare your pet’s fit with the costume size chart.
• Do not choose a size based on breed alone.

Using the chart and video helps you select a size with the costume’s sizing differences in mind. The listed weight range is a useful starting point for medium, while the chart and video provide additional sizing guidance.
