Using the jersey is super easy. Just slip it over your dog's head and fasten it around the body. Make sure it fits comfortably and doesn't restrict your dog's movement. When it comes to maintenance, you can machine - wash it in cold water with a gentle detergent. Avoid using bleach as it might damage the colors. Hang it to dry instead of using a dryer to keep its shape. Also, check the jersey regularly for any signs of wear and tear, and if there are loose threads, trim them carefully. And remember, this is an officially - licensed product, so treat it well to enjoy it for a long time.
