Using this dog t - shirt is easy. Just slip it over your dog's head and adjust it to fit. Make sure it's not too tight around your dog's neck or chest. When it comes to washing, turn the shirt inside out and put it in the washing machine on a gentle cycle with cold water. Use mild detergent. Avoid using bleach as it can damage the fabric and the printed logo. After washing, let it air dry. Don't put it in the dryer as high heat may shrink the shirt. Check the shirt regularly for any signs of wear and tear. If it gets too damaged, it's time to get a new one. Always keep your dog's safety and comfort in mind when dressing them up.
