We have a Pomeranian (not a tiny one). He’s 9 years old. He’s a rescue and we’ve had him about a year. He has always had a bit of a ‘wet willy’ which he licks a lot, sometimes grunting as he does so. We took him to the vet this week, largely about something else but mentioned this and she advised a urine sample. So.. any tips on how to get one?? Or what might be causing the issues? Thanks.
