I hope this doesn't start any conflict like it can in horses, but my puppy is kept at my SO's house with his family's two other dogs. Mine is fixed but the other two are intact. One is a Pom who they plan to breed and is pretty well mannered. The other is a dachsund who tries to breed everything he sees and is truly a pain. He is intact just because, no other reason. What are people's opinions on leaving a male intact just for the heck of it?
