It's a very healthy looking little tree!
You are right to want the branches to be more horizontal. Pears in particular tend to grow with very narrow branch angles which make them weak and prone to splitting, especially with a snow load, or when heavy with fruit.
I knew pears grew straight up and narrow. They almost look like Christmas trees!
This is a good time for you to start widening those branch angles while your tree is still young. You can make spreaders to help with that, which are basically wooden sticks with a notch in either end to fit against the trunk and branch.
I didn't know that I could spread the branches and train it to do something other that look like a rocket aimed at the moon. Thanks so much for this info. I just happen to have a young pear tree in the front yard!
Trees grow from the crown so if a branch is now, say, 3 feet off the ground, it will always be 3 feet off the ground.
It's a pretty tree, good luck with it.
