No, but the dog's life is in danger during the episode and when the episode ends the danger is still there when the screen says "to be continued." The danger is that Rudy wants to put the dog "away" (which apparently means the same as put the dog down) and Oscar has agreed to it. The dog is bionic, not robotic. It's a living dog with some bionic parts that physically enhance him.
A bionic dog (a living dog with bionic legs and a bionic jaw) has been a lab animal his whole life and for the last 4 years hasn't been allowed to leave the lab once. He spends most of his time in a cage and is only let out for testing, not for play.
A lab animal (a bionic dog) is sad about living his life alone in a cage. He also has nightmares about a fire he was hurt in (during the fire he was also in a cage).
