We have a shepherd/akita mix dog. We got Indie when he was just a tiny puppy (4 lbs when we brought him home. 45 lbs. now). He is the BEST dog. I do daycare in my home and was concerned that because he is a bigger dog, he might have problems with the kids. But that's never been the case. Indie is excellent with all the kids. He has never once touched any of their toys. He has his own and knows which they are. The kids can crawl right in his cage with him (it's in our family room) and he is fine with it.
Indie is 6 years old now. He has only ever even ACTED aggressive with one person. In that case, I had a little baby who was in a playpen. Someone came to my house to pick up a funeral video (my other job). This was someone Indie did not know. And the person walked straight to the baby's playpen. Indie immediately placed himself between the person and the baby and then growled up at the person. They backed off and Indie sat down right where he was and waited for them to leave.
Other than that, he's never anything except a teddy bear
Enjoy your puppy.
