This is such an adorable shirt! It's short sleeve and features a fun message on the back that says "Treats Are My Love Language". Anything that whimsical is sure to catch the eye of anyone your pet sees while wearing it. There's even a little heart in the word "Love" for an extra level of cuteness. The shirt is made of a thin material that's very soft to the touch, making it a perfect choice for warmer weather and outdoor activities. There is elastic in the midsection, but the back of the shirt is loose and non-constricting. One of the things I appreciate is that it's machine washable on the delicate cycle, so it's very easy to clean. It's not designed for the dryer, though. It will need to air dry, and the thin material will dry quickly. Cute and practical is always a winning combination, and this little shirt encompasses that perfectly. Leave it to Petco to create a line of cute and fashionable clothing that will have all the dogs looking dapper at the beach or the dog park!
