Hello, Thanks for the information and photo. I'd recommend making an appointment with your regular veterinarian for Jasper to be seen. He may need to be tested for some less common parasites, like coccidia or giardia. If he develops inappetence, vomiting, or lethargy, those would be reasons to have him seen by an emergency veterinarian sooner.
