It would be good if you can take a urine specimen with young the vet.
I usually do it by putting down a new potty pad, but put it plastic side up. When he urinates you can pour it into a clean cup or zip lock bag or suck it up with a clean empty syringe and take it with you. Don't put it in the frig.
