That is going to be one energetic dog. If you are asking will it be friendly to others or not, that depends on the dog and how well ultimately you socialize it. At a young age through to adulthood, you need to take your pup to the park and let it meet other people and dogs... if not it will be very territorial. You need to work on its behaviour immediately for how it is to behave when other people enter your home.
Let him sniff them, receive some attention, then have it lay down and behave. Otherwise it will become one of those glory hounds that has to be the centre of attention when anyone else is in the room.
One benefit of the mix of breeds you're talking about is that it should be one smart pup. Get it plenty of toys and some that are puzzles that they have to push it a certain way to get treats and such. Finally, make sure this dog has plenty of room to run and play!!
I have a boxer/lab mix who is now 14 years old. They are very loving,playful,loyal dogs. They are easily trained and very smart. It is all in the way you raise them. To keep your dog friendly take him among other animals and people. they also seem to be a very healthy breed of dog. In the 14 years old he only needed the vet for shots. Good luck with your dog.
Playful, loyal , protective
I'm sorry, but you haven't specified what type of dog you are talking about. But, certain types of dogs have certain types of temperaments.
Pit bulls, rottweilers, and dobermans are known for biting and attacking people, children, and other types of dogs for no apparent reason.
While labradors, and golden retrievers are known for being great with kids and are great family dogs.
