I am a first time dog owner and the breeder told me it's a great dog for a first timer. I completely disagree! Atlas is a high energy, at times highly stubborn and difficult to control dog. If not get a handle on, his barking is excessive. He challenges you fairly often and it's very difficult to get him back under control. That being said, as soon as we are in the house he switched to the perfect obedient and super easy trainable dog. He doesn't wake you up in the morning and is super calm. When he sees other dogs he goes straight into play mode and wants to have fun and play, play, play. I love my dog and invest a lot of time to learn from and about him and teach him as much as I can.
