Otto was a rescue pup, about 8 weeks when we got him. He was potty trained in a day and a half with only a couple accidents after when he had problems with his food. Learned sit & stay the first day. He tends to herd my small grandson (gently), so he requires constant correction on that. Definitely an alpha personality. He’s friendly to our cat, trying to share his toys, but unfortunately my cat is really mean to him. His favorite play is to push one of his balls all around the house with his nose while holding another ball in his mouth. We have hardwood floors, so he really gets a lot of speed going. We have a zip line outside for him and play kick ball. There is a bungee with a ball tied to it that he loves to jump and pull on. When he gets a treat he hides it for (sometimes weeks) later. He can be really destructive when left alone, even for a short while. He’ll get into things that he would never dream of if we were home. We provided him with LOTS of suitable chew toys so he never chewed things he shouldn’t. He’s great at communicating his wants, though at times can be demanding, so sometimes I make him wait. He loves EVERYBODY. I think if someone broke into our house Otto would invite them in for a beer! Scary bark, but nothing to back it up.
