To ensure the best fit for your pet, please measure the Chest, Neck and Back Length as shown below.  For most apparel items, the back length is the most significant factor.  If measurements are close you should consider selecting the next larger size. 

Please note that if you are ordering a custom made item, you must provide the Chest, Neck and Back Measurements before you complete the checkout.  Custom made items are not returnable due to sizing errors. Please contact us if you need assistance  regarding fit, sizes or taking measurements.
