There’s no real need to use the “biscuit training technique” for behavioral training as pet rocks are happy and eager to please you. A simple pat on your stone will suffice as positive reinforcement. Besides, relying on whether your rock’s stomach is empty to be sure it listens to you really isn’t such a good idea anyway.
Imagine your pet rock running out your front door. You call to him, waving a treat but he'd rather chase a squirrel or the mailman into the road than come back for a snack. Aside from the obvious danger of your little buddy getting hit by a car, he has now learnt that he doesn't have to listen to you if his belly is already full. Now, we’re not saying that you shouldn't give ANY treats to your pet rock. Treats can be great tool and motivator, especially when teaching fun things such as tricks.
Teaching your pet rock actual words
Remember that the two most important words that must be taught to a pet rock right from the beginning are the words “Good” and “No”. “Good” (which means “I like what you're doing”) and “No” (which means “Stop what you're doing”) are essential for good rock behavior. Once your rock has learned and understood these two basic words, training will be much quicker and easier.
The next step in teaching your pet rock a larger vocabulary is to simply place it onto a dictionary for a few minutes. Your rock will absorb all the words and definitions found within. Most rocks are very quick learners and you will find that once taught, your pet rock will be able to understand thousands of words and commands. You’ll be amazed that within a few hours, communicating and interacting with your new friend will be a breeze.
Just like teaching the acceptance of being handled, gentleness is also a very important thing every pet rock needs learn. As a new pet rock owner, you will need to teach your rock to be gentle when interacting with all the people and other animals that it may interact with. You will need to teach your rock how to restrain itself when it plays with humans and or other animals so that the playtime doesn’t get out of hand become too rough. If playtime becomes uncontrollable, someone or your pet could get injured. Remember, you must be the one to set the limits of ALL your rock’s behaviors... the good and the bad ones. Establishing this from the beginning will help you cement to bond between you and your pet.
