General information, not veterinary advice. Breeds, mixes and individual puppies vary; your vet can tell you how your puppy is growing.
Harness size by weight
Buy a harness for the puppy you have today, not the dog it will be: an adult harness slips on a puppy. Pupsize reads today's size from the chart below, then follows your puppy's growth pattern to say about when it will move up a size.
| Weight today | Typical size | Chest |
|---|---|---|
| Up to 5 lb | XXS | 9 to 13 inches |
| 5 to 10 lb | XS | 13 to 18 inches |
| 10 to 25 lb | S | 17 to 22 inches |
| 25 to 55 lb | M | 22 to 30 inches |
| 55 to 75 lb | L | 27 to 36 inches |
| Over 75 lb | XL | 32 to 42 inches |
Measure to confirm
Sizes differ from one maker to the next. Wrap a soft tape around the widest part of the chest, just behind the front legs, and check the number against the maker's own chart. An adjustable harness covers a few weeks of growth.
