The German Shepherd puppy in this video is in training. Kaiser is just 6 weeks old when he got started. The video is from 6 weeks to 5 months old. German Shepherds are intelligent and do very well with training. Look at how many police dogs are German Shepherds.
They do need to be socialized early on. They have protective instincts around strangers, so they need to learn to differentiate who are the good people and who deserves their suspicion. They need proper socialization so they can be polite with strangers and get along with other animals. Shepherds are good with other dogs and cats IN their own family. But they can be aggressive to dogs they do not know. And some do chase cats.
How to potty train a puppy
Michelle Welton of Your Pure Bred Puppy finds German Shepherds to be fairly easy to housebreak. However, she strongly recommends that you do it right from the start. 100% right, she stressed.
The first key: Until your puppy is housebroken, he does not have free access to roam the house on his own. You can use a baby gate to section off the kitchen, or laundry room. Except for the time you are directly interacting with the puppy, like feeding, grooming, walking, playing with him, taking him to the bathroom, the puppy stays in his area.
The second key is providing a regular place OR a constant place to go to the bathroom. Either take him outside every 2 or 3 hours (depending on the age of your puppy) or put a doggie door to a “potty yard” that is enclosed. With this second option, someone needs to be home, in case the puppy wants to stay outside and starts barking. A third option is to have a litter box (for small dogs) or newspapers.
