Name suggestions

My MIL is giving my son a puppy to grow up with 😅 I've already ordered a playpen for him to go next to my son's so they can see each other but have their own space . ❤️ Life is about to get interesting. What should we name him ? He is very shy and chill compared to his siblings they've been calling him canela I was thinking maybe Blanco to teach him words and colors or Winnie or Pooh my son has an entire Winnie the Pooh themed wardrobe and room (Also to add my current dogs names are Ellie and Lily)
