My dog has been limping and I found a blister/sore underneath her paw with an open wound. I don't know what it is or what to do or how to treat it.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If the limping seems to be worsening, I would rather have you take her to a veterinarian to be examined rather than wait any longer. If she has an infection deeper in the wound, you won't be able to reach it with topical disinfectants. She should probably be on an oral antibiotic and pain medication to help reduce any inflammation. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please remember to rate this answer as helpful or not. Thank you!

Any topical antibiotics that you apply will likely just get licked off. I would just wait until you can have her evaluated by a veterinarian. Until the appointment, make sure she isn't licking it, as this can cause damage or ulceration to the skin and spread bacteria. Since she limps when she walks, this means she is painful, so trying to keep her as still as possible will help with pain. I would skip walks or play time until Monday

Ouch, that looks quite nasty and should really be looked at by your veterinarian as this could be a nasty cut or even a torn off toe or open fracture. Even if it hurts less now, there still is a good chance of this getting infected, so your veterinarian may want to prescribe an antibiotic for your dog and even bandage the paw to keep dirt from entering the wound.
