Hi Kam
This is a complex problem that is best dealt with in a porper consultation with an animal behaviourist (www.animal-behaviour.org.za), but it seems your toy pom male needs to be castrated as he is marking his territory. As it seems you want to breed the dogs, castrating him may not be an option. This behaviour may also be caused in part by his wanting the attention that the younger one is getting (jealousy) and partly due to his being an entire male - testosterone levels are high at this age. Is the female on heat? If so, this may be a reason for his possessiveness. Sometimes urinating is a sign of submission, so be careful how you deal with the weeing as he may be doing it as a sign of respect. Without more information and observing the dogs it is hard to answer your questions.
