Even if it's unfortunate, the unexpected can happen. If in doubt, you can send us the measurements of your dog and a photo with the coat. It will be our pleasure to help you. If you wish to make an exchange, please note that we accept exchanges for another size within 15 days of the date of receipt provided that it is has not been worn outside and let it be in its original condition. Please note that there may be a price difference between two sizes. If it is not possible for you to go to our workshop in Sainte-Eustache, we offer you to use our Purolator services at the same price as us, either $25 for round trip transportation items. In this case, we will send you the return label by email. *Only for Quebec and Ontario customers. For out-of-province or international customers, contact us to establish the most advantageous option available.
