Use This Size Guide to Measure Your Dog for the Perfect Fit:

1. Neck: Use a soft measuring tape to measure around your dog's neck.
2. Chest: Measure around the widest part of the chest, from just behind the front legs and back up to the same point on the other side.

3. If you're in the upper range of a size, it's recommended to move up to the next size for a better fit.

Please note that sizing may vary between brands. For example, an XL in another brand might be a Large in ours. Accurate measurements will ensure the best fit for your dog.
