Dog Collar Size Chart

Size Fits neck Typical dogs
Small 8.5" – 12.5" Toy breeds, small puppies
Medium 11.5" – 17.5" Beagles, terriers, small to mid breeds
Large 13" – 21" Labs, retrievers, mid to large breeds
XL 16" – 27" Large and giant breeds

Between two sizes? Pick the larger one if your dog is still growing, and the smaller one if your dog has a slim neck.

How to Measure Your Dog's Neck

  1. Use a soft tape measure, or a piece of string you can lay against a ruler.
  2. Wrap it around the middle of your dog's neck, where the collar normally sits.
  3. Slide two fingers under the tape. It should be snug but not tight.
  4. Read the measurement and match it to the chart above.

Which Width Is Right: 1" or 1.5"?

Both widths are strong enough for big dogs, so choose the look you like. A 1" collar is lighter and works on every size of dog. A 1.5" collar is wider and bolder.

Dog Leash Sizes

  • 4 ft leash: keeps your dog close. Good for city walks, busy sidewalks and training.
  • 6 ft leash: gives your dog more room to explore on trails and in the park.
  • 1" or 1.5" width: a 1" leash is lighter in the hand and still strong enough for big dogs. A 1.5" leash gives a wider grip and a bolder look.
