QuestionCan he produce puppies already? And how old are male poodles when testicles drop?
Answer4 months is a little early for the testicles to be completely descended, but not unknown. I wouldn't expect him to be able to produce much of a litter now, but he is certainly not to be trusted around a female in season.
I really hope that if you are thinking of breeding, you do a lot more research. To get a good idea what quality breeding requires, go to http://www.woodhavenlabs.com/articles.html#breeding
