Dog Tee Shirt – 2-Pack Summer Essentials for Large Dogs Soft breathable quick-dry athletic knit keeps your Lab, Pit Bull or similar large breed cool and dry all day. Four-way stretch lets him run, jump and roll without rubbing or riding up. A discreet reflective strip on the back flashes under headlights so evening walks stay safe. The light layer blocks harsh sun, guarding thin-coated skin from burn and overheating yet still lets air flow. Bright colorfast hues survive machine washing and backyard play having two shirts means one is always clean and ready. Check the size chart and choose Xxl for a roomy fit if your dog is between sizes or still growing, size up for comfort.
