My dog has a blister on his toe near the toenail. What is it?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 10 years and 1 month old | 30 lbs

Dog has a big blister on his toe. Its not in his webbing, but on top just beyond his toenail. I'm not sure how long its been there, I just noticed today. Possible he got stung by something outside in the backyard or bit by an ant? Doesnt seem to bother him. He is walking fine and not licking it. Thank you!

Oh goodness! That looks sore! It actually looks like it could be an infection of the toenail bed, or a tumor of the nail bed. Soaking in warm water with Epsom salts would be a good thing to do tonight until you are able to get him to a veterinarian tomorrow. They may want to do a needle aspirate and/ or and x-Ray to help make a diagnosis. Best of luck and I hope he improves soon. Thank you for using Pet Coach.
