New situations can be scary to your rottweiler if you haven't exposed him to them. For example, if your rottweiler is a country dog, he's likely to be overwhelmed by a walk in New York City. Likewise, a dog from Manhattan might be shocked to see a herd of cattle. While you can't prepare for every possibility, you can expose your rottie to as many new experiences as possible. With each new experience, he becomes used to seeing more new and unusual things. When he finally does see that herd of cattle crossing in front of your car on a road trip to Texas, he may be a little surprised and even excited, but he's not frightened, intimidated, or aggressive.

So what sort of experiences should you expose your rottie to? Certainly, you should start with those situations he's likely to experience in his life: trips to the groomer and veterinarian; riding in a car; meeting strangers and children; meeting other pets; seeing people in various types of clothing, such as winter or summer clothing and raingear like umbrellas; seeing squirrels, deer, or other wildlife; holidays like Halloween and Christmas where there is a lot of noise and people; fireworks; and visiting other people's homes. You may also want to expose your rottie to experiences he may not have often — visits to the ocean, forests, or mountains; visits to the city, where he may not be allowed everywhere but is allowed outside; trips to the boarding kennel; and other places.
