1. Choose a pair of women’s underwear, and choose the size of women’s underwear according to the size of your dog’s butt.

2. Let the dog wear the selected women's underwear first. If the size is suitable, find the position of the dog's tail and mark it, and finally take off the underwear worn by the dog.

3. Cut a cross at the marked place. Be careful not to cut it too big, because this is where the dog’s tail will be pulled out. As long as the size matches the size of the root of the dog’s tail.

4. Finally, for the sake of beauty, you can prepare some decorations and sew them on the underwear with a needle. The specific details can be decided according to your own preferences.

5. When using, first put a sanitary napkin of appropriate size on your dog and then put it on.
