Training a German Shepherd to Sit
ByGerman Shepherd puppies are intelligent and training one a new trick is not a hard task. If you plan on starting training your German Shepherd puppy then it is probably best that you start with one of the easier tricks,
like training a German Shepherd puppy to sit. Training the German Shepherd puppy to sit first can help out in the long run because having the German Shepherd puppy sit during other training tricks comes in useful.
Find a good location to start training the German Shepherd puppy. It should be a quiet place where not too many things can distract and steal the German Shepherds attention from the training. It is probably not a good idea to start your German Shepherd Training in the park because there are a lot of distractions there which can make the training difficult.
When you find a great place, just get a couple of dog treats for your German Shepherd puppy and you can start the training. Take a treat and bring it up to the German Shepherd puppy. Hold the treat high enough so the puppy is looking up at it but not too high or the German Shepherd puppy will try to jump to get it. Now move your hand forward, towards the dog, and say the sit command. Your dog will sit back when the treat is too close to him. When your German Shepherd sits down give him the treat.
Keep doing this until your German Shepherd puppy will sit without you moving the hand forward. If your dog loses interest in the treat then stop the training and try to train the German Shepherd puppy to sit some other time. After some time your German Shepherd puppy will sit even without the treat and that’s when you can begin training the German Shepherd dog new tricks.

we just got a puppie german sheperd and we have 1 big cat and a kitten. She does not get along with the cats. what can i do.
You will have to slowly introduce them to each other. Its much easier to do while your puppy is still young.
Your German Shepherd might also be just curious and might just want to play with the kitten and not necessarily hurt it. However, you still should keep your puppy on the leash when you’re introducing the two.
