Snoopy has to see a vet immediately. This ulcer needs to be cleaned in a sterile manner, and may need be sutured to help it heal. Please do not give him any more of your daughter's penicillin. It's never safe or recommended to self treat your animal, and you could be giving him an incorrect dose that may do harm to him. This will be painful to him, and he likely needs pain medications to treat this. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given. Snoopy needs to see a vet now for this for treatment and safe medications. Please bring him into an ER vet or find a vet on call to see him now.
