My “Why?”
My dog Nero suffered a concussion as a puppy. He was hit in the head with a tennis ball while playing fetch. You may not know, but to adjust a puppy it only takes the pressure you would use to test the ripeness of a tomato. The hit on the head was more than enough to misalign his skull bones. He was left with uneven pupils, anxiety and headaches. His eyes would not track together or respond to light in sync.
