Another issue that can be noticed with male Pomeranians is a white to yellow colored, thick discharge that occurs right after the dog urinates.
In many cases, this as well can be attributed cells and matter that is normally located between the sheath and the penis. The act of peeing can make this materialize; and therefore this is typically nothing to be concerned about.
With this said, if a male Pomeranian has this sort of penile discharge and there are other signs such as very cloudy urine, frequent urination and/or signs of straining or pain during urination, this may point to a bladder or urinary tract infection (UTI); this is an issue that need to be treated by the vet.
Males are treated for UTIs and bladder infection the same as females, with a course of antibiotics, usually taken for 7 to 10 days.
