My dog has a growing lump on her paw. Does it need antibiotics?

Pet's info: Dog | Bluetick Coonhound | Female | unspayed | 10 months and 17 days old | 48 lbs

Hello- I noticed this spot on the side of my dog's front left paw a week or so ago. It has gotten bigger and she does lick it butI dont see her do it obsessively. I'm wondering if it may be something that can be taken care of with antibiotics or a topical spray?

Hello, thank you for suing PetCoach. Most likely this is benign histiocytoma. I have linked an article for you below about this issue. Basically it is a common benign tumor that is typically seen in young dogs and on the extremities. It regresses on its own within a few months. No treatment is needed however, is some cases, giving Benadryl has seemed to make it go away sooner. For a 48 pound dog I would give two of the 25mg Benadryl (diphenhydramine) capsules twice a day until you notice it reducing in size. Yes, dogs take a much higher dose of Benadryl than we do. I would not be overly concerned about this but we sure don't want her licking it so if her licking gets excessive, you will need to put a cone collar on her to stop that.
