Bandit09's right. The crate should be big enough for them to stand up and turn around. It should also be small enough that they can't have an area that they can potty in, and hang out in the rest. Dog's generally don't like to be in the spot they potty in. Some people partition a larger crate, then make it bigger as the dog gets bigger. My two small ones share a crate.
At 1 year, he should be able to hold it for a while, so that shouldn't be an issue. It may be that he just isn't used to having to hold it. I am not an expert in housebreaking, so I will leave that to others.
