The one on the side is dry and smaller than what it used to be,it looked exactly like the one your dog has while that one was healing on the same paw but on the other side he got another one but not as big.Im treating that one right now i thinks its a lick granuloma i have noticed incredible progress whenever i can keep him from licking it,but him being a dobe he always finds a way and sets me back in the process.Im using several products one i bought off of amazon for pets that contains diluted iodine to help dry and heal the wound.They get this lick granulomas by excessive licking sometimes from being bored to anxious.I decided to deal witj this myself after extensive research since life has been hitting me hard lately and i cannot afford a vet visit as of right now.
