So my puppy has a swollen toe on the inside of her left paw. Last night (before it was swollen) every now and then she would wimper and lick at it. I looked for any noticeable thorns or splinter but saw nothing. Just this morning is when I noticed that it was actually swollen, she still runs and plays but she babies that paw. Should I take her to the vet today or wait a few days while assessing the situation?
