Great Dane/Malamute Mix Puppy

Hello, we are having to rehome our 5 month old great dane/malamute mix puppy, Bo. Due to life's circumstances, we are unable to keep him and unfortunately have to rehome him. We are getting desperate, and have tried many different avenues that have not worked. He is not neutered. He is very playful and energetic, good with all other dogs he has encountered and has shown no signs of aggression, listens well to basic, simple commands, and is a very good family dog. He is also very good with kids.
