Size Guide
How to Measure Your Dog
- Neck circumference: Measure around the widest part of your dog’s lower neck. Leave enough space so you can easily slip two fingers between the collar/harness and your dog’s neck.
- Chest circumference: Measure at the widest point of the chest, typically a hand’s width behind the front legs. Go once around, holding the tape measure snug but not tight. Allow two fingers of space to prevent chafing or constriction.
Important Reminders
- Individual Variation: Dogs of the same breed can vary widely and there are no standard collar/harness sizes across brands.
- Measure to Confirm: Use a soft tape measure for the most accurate neck and chest sizes.
- If in Doubt, Size Up: A harness or collar that’s too tight can be uncomfortable or unsafe.
- Breed Charts: While we strongly recommend measuring your pup for the best fit, we’ve added some common breeds to our size charts below for guidance if measuring isn’t possible (e.g., buying a gift).
