Picked up a 14 month old male English Staffy last weekend and wondering if we should get him desexed. He is our only dog and is secured within our backyard. The only time he is out of the backyard, will be for walks however he'll be on a leash 100% of the time. I've heard people say it makes them less aggressive and eliminates the chance of getting testicular cancer however I'm not completely sold on the idea, especially if it means he'll suffer a great deal of pain. Thoughts please
