Sizing Chart for the Pups
Every dog is different in size and shape, so please make sure that you measure and double check the sizing of your fur-baby before making a size selection.
Please also note, our sizing may be different to other brands that are on the market. Ensure that you double check the sizing of each harness. We would recommend not assuming that you will be the same size as another brand.
Also note that each Harness Type does have a different sizing, so please ensure to check the size chart prior to purchasing, as your pup may be in a different size in each type of harness.
If you're still not sure which would be the best fit, send us an email to info@bigandlittledogs.com with the following details and we will suggest the best fit for them:
1. Measure around the widest part of the base of the neck (the area where the collar would naturally sit)
2. Measure around the widest part of your dog's ribcage, just behind their front legs
3. Which products you would like sizing suggestions for
Here are a couple of tips for sizing:
- For neck and chest, please allow sufficient room to slip two fingers (stacked on top of each other) between the measuring tape and the dog’s neck or chest. A snug fit is what you are aiming for - just make sure it is not too tight or chokes your pet.
- Order the next size up if your dog falls between measurements.
