My dog keeps biting his paw. Is it an interdigital cyst? Home remedies?

Hi, I have noticed my dog Cooper biting at one of his back paws for a couple of days now. He finally let me take a look at it. I can’t get a picture because he’s not having it, but I looked it up online and it looks like it could be an interdigital cyst. It looks similar to the photo I attached. Is there anything I can do for him at home? I have some medicine that I can apply from a previous bacteria infection he had. I was told it works for most skin issues. Or if he would need antibiotics?

Thanks for using Petco Pet Education Center, formerly Petcoach! While this is possible, keep in mind that there could also be something like an abscess going on. Other possibilities include a mass or tumor. I would encourage you to have Cooper evaluated by a veterinarian for further assessment and treatment. They would be able to check on this and recommend therapy accordingly. Best of luck!
