Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This discharge that you see has nothing to do with a kidney issue. This may be due to a polyp within the colon that is causing this discharge or it may be that Pepi has arthritis that is affecting the anal sphincter allowing some of teh stool to leak out.
The best thing to do is to take Pepi to your vet for an exam. This will check for metabolic issues and chaeck for arthritis.
For now, try giving Pepi aspirin at 5 mg per pound every 12 hrs which will decrease the inflammation that may be compressing the nerve supply and allowing this discharge.
If there is no improvement, have your vet check Pepi.
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.
