Good Morning and welcome to Just answer. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This swelling you see is due to either fly bites or this swelling in the sheath that moves to the lower areas due to gravity. This is not unusual and will not harm Raffles. You should check his sheath and penis for a bean or clean his sheath that can cause this swelling. Since this is late in the year, you probably do not have many flies but this line could form an abscess so watch for this.'
In most cases, this will not harm Raffles and is only secondary to the swollen sheath.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please Reply so I can clarify for you
