Sizing Chart
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.
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 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.
