Dogs with a Level 5 Wolf Mount ability take 1 heart of fall damage after jumping. The player riding the dog also takes about 1 heart of damage.
Edit: Pillow Paw would solve this problem, so I'm not sure if this is working as intended

Not an intended feature to take fall damage after maxing an ability. New jump heights are as follows: (lvl 1-4: starting at half a block going up to 2 blocks high jump, lvl 5: 3 block high jump)
