Three-month-old German shepherds can be trained in a variety of ways, depending on their temperament and personalities. Start with simple commands like “sit”, “down”, or “stay” for puppies that are hard to train. 

Once you’ve mastered these commands, you can move on to more complex things like obedience and agility.

Potty train:

Potty training a three-month-old German shepherd starts with a routine. Make sure your dog knows where their destination is before you let them out. Tell them “Go”, “potty”, or “drop it” once you get to the Spot. 

If they do not leave within 5 minutes, bring them back inside and give them another chance later. Continue this process every day until the puppy can go in the potty without any assistance from you.

Behavior modification:

When dealing with difficult behaviors, such as obedience, behavioral training is often used. It is based on techniques that work well with German shepherds and should be begun at a young age. Some behaviorists use cue words as part of the training. 

For example, “stay”. Give treats when the dog does what you want. When the dog obeys, praise them.

Orientation training:

Dog obedience training is a very important step. It teaches your 3 month old German shepherd to listen and obey simple commands, such as “sit,” “down,” and “stay.” 

Teach your pup basic commands like sit, stay, and down. After you’ve mastered these, you can move on to more complex tasks like coming when called and staying outside when asked. If the puppy doesn’t listen the first few times, don’t get discouraged. 

Stick to your routine and eventually, they will learn to obey.

Agility training:

Dogs bred for agility are very common among German shepherds. You can train your dog this way so that he can move around quickly and efficiently. Dog agility classes can be a great way to teach your puppy tricks, such as jumping through rings or going up and downstairs. 

Begin with the basics, such as coming when you call and sitting where you are supposed to. Once you have mastered these, proceed to more complex exercises, such as jumping over obstacles and running in circles. 

German Shepherd agility training keeps them active and entertained.

Vocational training:

German shepherds are also often bred for working alongside people, such as being search and rescue dogs or guard dogs. During this type of training, your pup learns how to react in an emergency appropriately. 

When you are teaching your puppy the basics such as responding to commands and sitting at a designated spot when instructed to do so, you should start with the basics. 

When you have mastered these, you can begin working on more complex tasks, such as locating objects or staying outside when you’re asked to do so. 

There is nothing better than putting your German shepherd through vocational training to teach them how to be responsible and how to use their skills efficiently.
