Thank you for submitting your question regarding Jasper. You may consider seeing his veterinarian again or seeking a second opinion regarding his skin. The lesions look severe. He could have a food allergy. While this could affect all of his skin, the lips and anus are typically affected. There is also a condition known as perianal fistulas. This requires prompt treatment with medication to suppress the immune system. He could also have an condition where the body attacks it's own skin cells. This would be accompanied by skin lesions in other places as well. He may require skin biopsies or an exam under anesthesia to reach a diagnosis. Good luck!
