Due to the fact that our garments are made to order, we ask that you review our size charts and measure your pet 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 pet tank is a perfect choice to show off your pooches style.

HONEST PET APPAREL IS MADE WITH THE FOLLOWING - Tank: soft, stretchy 65% Cotton & 35% Polyester (our fabric is soft and both breathable as well as sweat-resistant. Polyester also reduces wrinkles and doesn't shrink as much as cotton in the dryer). Graphics: CPSIA certified Vinyl Heat Transfer (safe for a new born baby as well as your precious pooch) WHY CPSIA CERTIFIED VINYL? *Unlike screen printing method, heat press is clean and environmental friendly. Screen printing methods involve lots of chemical combinations that may be dangerous. *Extremely durable! Most cuttable transfer vinyl will last the life of the shirt. This is great for pet apparel as they are normally worn frequently and go through a lot of wear and tear. Vinyl is a extremely durable product that resist cracking, peeling and fading. Thanks for shopping with us! We look forward to outfitting your fav fur-person!
