Thank you for your additional order, Nikukyu-sama! I knitted one round to measure the size, and it was a tight fit, so I'm knitting another round. The side with two buttons is the front, and the side with one button is the belly. Please fasten either the top or bottom button at the appropriate spot under the neck. You can fasten both buttons, but it may restrict your dog's front leg movement, so please use them while observing your dog. This is made of 30% alpaca and 70% wool. For washing, hand wash in a washbasin with wool detergent, rinse, gently wring out the water, absorb excess water with a towel, and then hang to dry. #dogclothes
