Hello, This is Dr. Christian.
Is she licking at the paw too?
She has only a couple of time, then yelps shortly after. Its like she wants to lick or bite it but its too painful.
Thank you for that information. Considering the redness and the worsening I would worry about an infection or perhaps even something under the skin (such as a thorn). It would be best to have her seen as soon as you can by your regular vet. You could try soaking the paw in warm epsom salt water for 5 minutes 2-3 times a day. Make sure to rinse it thoroughly afterward. Some ice afterward may also help.
Will do. Thanks Doc!
You're welcome. Good luck. I hope she feels better.
