Got him at 7 weeks. Use him as a guard dog. Extremely intelligent, and very docile until we tell him it's "go time". When we first got him he was energetic all the time, we trained him to whine when he is hungry, or needs to pee. Growl only when playing, and bark once whenever someone enters the house, and twice whenever someone enters out room. He is trained now to bite if on guard, and lick at all other times. For only seven months old he has amazed me. It takes a lot of training. He is trained to sit every single time I stop walking or moving, and at every cross walk. He is trained to get onto furniture when called only. He is trained to walk off leash and on. He can sit, come, lay, down, speak ( sing ), guard, alert, attack, follow, rest, stay, climb, and a few more. This isn't my first guard dog as I grew up with them but for being in collage full time and he comes to class with even though he's not a service dog. And I work full time. He has been amazing. Doesn't dig in our fenced back yard, although he can climb over it. He still doesn't climb over it.
