Senior Shihtzu with health issues. Last grooming?

Today I'm grooming a 15 year old Shih tzu. I didn't know he'd been peeing blood for months. Nobody even told me. I didn't even know till half way through the grooming.
He didn't seem to be in pain, so I went ahead and finish. I'm not sure he'll be back.
