Dog swimwear fit guide
Measure chest girth first, then confirm length.
For dog swimsuits and rash guards, the garment should sit close enough for water movement without pulling under the front legs. For life jackets, follow the product-specific chest and weight range.
| Size | Chest girth | Back length | Best for |
|---|---|---|---|
| XS | 12-15 in | 8-10 in | Puppies and very small breeds |
| S | 15-18 in | 10-12 in | Small dogs |
| M | 18-22 in | 12-15 in | Small-medium dogs |
| L | 22-27 in | 15-18 in | Medium dogs |
| XL | 27-33 in | 18-22 in | Larger dogs |
Between sizes?
Choose by chest girth first. If your dog has a deep chest, thick coat, or broad shoulders, leave more room and ask support before ordering.
