Who told you about poking the bladder with a needle? My vet uses an electrical device that causes the urine to release. Not that much either but no needle. My current vet suggested I use a clean jar lid and when she squats slip it under her rear. This worked when she was a pup. If a boy, then I have no idea how to get a sample. Good luck.
