Why is there a lump between my dog’s toes?
Expert Answer
A bump between a dog’s toes may be caused by external impact, interdigital dermatitis, or a cyst. In this case, the owner can try disinfecting the area with iodine and applying a topical anti-inflammatory, anti-swelling medication. Watch whether the symptoms improve.
If there is no improvement or symptoms worsen, consider whether it is from infection. If it is interdigital dermatitis, the dog also needs antifungal medication.
My dog got a toe lump from interdigital dermatitis and iodine plus an antifungal cleared it, but I checked first that it wasn't a foreign object or cyst. Clean the area, keep it dry, and watch, if it's not shrinking in a few days or looks infected, a vet should look, because some cysts need draining. Between-toe spots stay moist and angry if ignored, so don't just hope it resolves, keep it clean and dry.
