Measure comfortably around your dog's neck where the collar naturally sits with a flexible tape measure or length of string. You should be able to fit your first two fingers between the collar and neck. Our collars are available in four widths: 3/8", 3/4", 1", and 1.5". Check out the size chart below to determine your pet's size here at Sew Fetching. If your dog is in between two sizes there is some overlap - but if your dog is still a puppy, we recommend sizing up. There are also a number of upgrades available to help create the perfect collar for your pup.

If you're still unsure what size would be best, or if you would like a custom size, don't hesitate to contact us as we'd love to help!
