As of the 2022 holiday season, we will not be taking international orders. Every holiday we encounter package losses that has caused our clients and ourselves frustration with in-country postal support. Once the New Year has passed, we'll revisit to see if the interest is there. If you are interested, please send us an email to with your interest in ordering from us and where you are located. We hope you can understand.

If applicable, please make sure to verify your pet's size for each individual item. And, if it's for a puppy, please order up. They usually outgrow items before it even arrives. Click here for Size Guides
