Dog and boy missing a leg

Today we had to watch a video and then do this drawing to give information about the video.

The video i watched was about a boy in a dark lounge playing a video game then his mum comes in with a cardboard box and opened the blinds, he opens the box he grabs the dog and thinks its cute until he see it only has three legs, so then he throws the dog onto the ground and continues playing his games. The dog starts to goof around which distracts the boy but he try´s to pretend he doesn't care, but eventually the dog wins over the boy with he´s cuteness, the boy grabs his crutches and struggles to get off the couch because the boy also has a missing leg. So they limp out together and play ball.
