Doberman Pinschers are considered one of the most loyal dog breeds in the world. That’s why they are in the military in many countries. But on the other hand, if someone provokes them, they can be very aggressive and dangerous. Therefore, they must be trained and socialized properly from an early age. If you are a new dog owner, it’s not wise to get a Doberman doggo as your first dog.

If they don’t get their necessary activities (and get bored), they can be aggressive and cause destruction. They can also be more aggressive toward strangers and other animals than average. Therefore, if you are hoping to get a Rottweiler, it’s better to know more about that breed before getting one. You can ask other Rottweiler dog owners about their experience and get a good idea about this breed’s behavior.

Even though Chihuahuas are small in size, they are famous for being aggressive little sweeties. This is actually true but not completely. This breed behaves well when treated respectfully. If they get annoyed, then they can get aggressive. If you have matured children at home, then it’s not a problem to get a Chihuahua (assuming they treat the dog respectfully). If there are small kids at home, then that would not be a good idea to get this dog because they might show aggression if your kids don’t show respect. If this breed is socialized properly from an early age, then that aggressiveness will reduce significantly.

People can easily get scared because of Cane Corso’s appearance. As you can see that if you see this doggo at night, it can surely give you a mini heart attack. Regarding behaviors, it’s a lot like American Pit Bull Terrier. They are devoted to the family but can show aggression if they sense a threat. So it’s better to be an experienced dog owner if you are hoping to get a Cane Corso because this is not an ideal doggo for a first-time dog owner.

So, if they sense danger, they will not be afraid to follow their instinct. But if you socialize Dogo Argentino from a young age and train them properly, their aggressive behaviors will reduce a lot. But it’s better to consult with other dog experts before getting a Dogo Argentino because you might not cut out to be an owner of this breed.

Life Span – 10 – 12 Years
Temperament – Strong-Willed, Loyal, Mischievous, Intelligent, and Sensitive

This breed is very intelligent. Therefore, they learn tricks quickly. But, they are also stubborn and independent. That means it can be difficult to train them. So, you have to be very good at training them and should have lots of experience with dogs. Otherwise, it would be very difficult for you to handle a Rhodesian Ridgeback.
Wolf-Dog Hybrids
This means an animal that is a part domestic dog and part wolf. Since this means they are half wolves, this breed will have a lot of traits of a wolf. Therefore, it’s not good to have a wolf-dog hybrid as a pet. If you are a dog expert, then it’s not a problem to get a wolf-dog hybrid (after doing proper research and consulting with experts). But keep in mind that most of the wolf-dog hybrids will show lots of aggression. Therefore, they will require constant monitoring. If you can’t provide that, it’s better to not get this kind of breed.
