Using this dog t - shirt is easy. Just gently put it over your dog's head and adjust it to fit. Make sure it's not too tight around your dog's neck or body. When it comes to washing, you can toss it in the washing machine on a gentle cycle with cold water. Avoid using harsh detergents as they might damage the print and fabric. Hang it to dry to keep its shape. Always check the fit regularly, especially if your dog is growing. And keep it away from sharp objects that could tear the fabric.
