My puppy just had her back dew claws removed. I noticed that she has been licking a little so I looked at both of her feet. She has ripped her stitches open on one foot and a small piece of skin is just hanging by one stitch. My vet's office is closed

My puppy just had her back dew claws removed. I noticed that she has been licking a little so I looked at both of her feet. She has ripped her stitches open on one foot and a small piece of skin is just hanging by one stitch. My vet's office is closed until tomorrow and I do not have any badadine to clean it. What do I do?
