General information, not veterinary advice. Breeds, mixes and individual puppies vary; your vet can tell you how your puppy is growing.
Collar size by weight
A puppy's neck grows fast, so most owners buy two or three collars in the first year. Pupsize reads today's size from the chart below and follows your puppy's growth pattern to say about when the next one comes.
| Weight today | Typical size | Neck |
|---|---|---|
| Up to 6 lb | XXS | 6 to 9 inches |
| 6 to 12 lb | XS | 8 to 12 inches |
| 12 to 25 lb | S | 10 to 14 inches |
| 25 to 50 lb | M | 14 to 20 inches |
| 50 to 80 lb | L | 18 to 26 inches |
| Over 80 lb | XL | 22 to 30 inches |
Measure to confirm
Sizes differ from one maker to the next. Measure around the middle of the neck with a soft tape and check the number against the maker's own chart. An adjustable collar covers a few weeks of growth.
