•Before placing your order, please make sure you have the right size since we have a no refund or exchange policy. •If you have any questions about measurements, feel free to contact us so we can help ensure your furry friend gets the perfect fit. •If you're not sure about the size, we suggest going for the next size up. That way, you can tie a knot first and then snap the button. *This works great for fluffy dogs too, especially if their size changes after a grooming session.
