What is this n How to Rid of it?

Hello, we just moved into our house n in back yard we found out we have this pear tree. Our backyard is surrounded by 6 neighbors n 4 of them own dogs. The limbs were hanging low touching the ground but we soon cut them to make look like a tree again. We moved in in June 2018 n I noticed most leaves had these yellow splotches n sum branches had the lil balls on them…well now wen I looked at them up close…there are these spiky things on leaves now but most of the leaves have these yellow blothes wit spikes n pears are growing into shape of pears too. Don’t know what this is or what to do…cuz wuld be nice to be able to eat these pears in future…
