The photo is a little fuzzy so its hard to say. It may be an oral papilloma, which is due to canine papillomavirus. Typically these resolve on their own, but many more may pop up over the next few weeks on his lips and in his mouth. It could also be an inflamed hair follicle or a skin infection. If its not resolving over the next few days to weeks, or if it seems to be getting worse or causing him discomfort, please take him to your vet to be evaluated. Here is an article on canine papilloma virus. http://www.pethealthnetwork.com/dog-health/dog-diseases-conditions-a-z/oral-papilloma-virus-dogs Thanks for asking PetCoach!

    Thank you for submitting your question regarding Yote. I would definitely ask your veterinarian about the new bump at the appointment. A procedure known as a fine needle aspirate will likely need to be performed. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will hopefully give a diagnosis for the mass. A histiocytoma is a benign growth that is common in young dogs. Unfortunately, a mast cell tumor is an aggressive form of skin cancer and has the same outward appearance. I hope this information helps!

    If your dog is less than two years old, I am suspicious of a histiocytoma which is a benign tumor that will go away on its own within a few months. If he is older than 2 years old, it could be a papilloma (wart). If they spread or multiply, see a veterinarian for a more accurate diagnosis and treatment. Best of luck to you and Motivate!

    I recommend to have Junior examined by the veterinarian. Skin masses can be many things but red raised masses are especially concerning for a skin cancer called a Mast Cell tumor. Your veterinarian will need to collect a sample of cell to examine under the microscope to determine what this is and if further treatment is needed. Have this checked out soon.
