Transition to the crate needs to be a gradual thing so that you don't overwhelm him. Reward him for stepping in the crate with a treat and give him time to associate the crate with positive things.And slowly increase the amount he stays in the crate and rewards are the key, especially with beagles, they are extremely food motivated. Beagles are the best dogs out there! Trust me, you're in for a ride! Mine just turned one and she still hasn't lost any energy.
