I'm sorry to hear about the passing of your pet. Unfortunately, without an autopsy, it's impossible to know for sure why this happened. It's possible he had an autoimmune condition or a tick borne disease. These could result in skin lesions and ongoing internal issues. A genetic condition is also possible which resulted in over all poor doing. Lastly, chronic poisoning could also show up like this. It sounds like you and your veterinarian tried to save him. Take comfort in knowing you did what you could and try to remember the happy times. My condolences.
