What problems can my intact male dog face if I don't neuter him?
The main reasons that most dog owners opt to neuter male dogs are behavioral - urine marking, roaming in search of females, and not getting along with other male dogs are all common problems for many intact males. In terms of possible medical issues, as they get older they often develop issues with prostate enlargement, prostatic cysts, or infections. Testicular tumors can also be an issue. And of course, you have the lifelong responsibility of making sure that your dog does not contribute to the pet overpopulation problem by fathering any accidental puppies.
If you don't mind the behavioral issues and are prepared to keep your dog safely confined to prevent roaming, then you don't necessarily need to neuter unless medical problems develop. It's definitely a personal choice, not a one-size-fits-all recommendation :)
