I once owned a Labrador named Pascal, that had failed guide dog school. He was highly trained, but over excited. That's why he failed. See, my brother has autism, and my mother heard that sometimes, these 狗 can be really good companions for autistic kids. But after a few months, my bro got sick of him, and didn't like his smell either. He was too neglected, so we sent him back to the guide dog association.
