Wingman Dog Shirt Due to the fact that our garments are made to order, we ask that you review our size charts and measure your dog to determine the perfect size before placing your order (please refer to "Size Chart" and the "How To Measure" pictures above). Please note, if you are stuck between sizes, it’s always better to go up a size than go down a size! Thanks for respecting the process, we can't wait to make your perfect Honest Dog Co apparel piece! Winter, spring, summer or fall our light weight stretchy cotton/poly blend dog tank is a perfect choice to show off your pooches style. We have enough designs to keep your fashionista at the top of their fashion game for every holiday and occasion.
