Christmas dog story.
Daughter's boyfriend comes from a deaf family. His parents and siblings were all deaf from birth but he got lucky in the genetic lottery. Daughter has a husky who is big and boisterous, his mother is old and frail, so they never took the dog to mother's place. A few weeks ago they went over for a few hours with the dog and it turned out the dog and mother got on really well, so they decided to do a 3 day pre-Christmas visit.
It went well. They started teaching the dog commands in sign language. Amazing really, in just 3 days the dog learned more commands in sign than he ever knew in spoken form, she never did many commands with him before. He picked them up really fast. The first one was stop. He got that in just a couple of hours.
