The ancient people of Italy used the Neapolitan Mastiff as guardians. With their intimidating size and stance, the Neo was more than enough to stop any intruders. Despite their intimidating exterior, these dogs are actually extremely loving and can be considered a gentle giant. The Neo is characterized by their large size (120-175 lbs.), loose skin, and heavily wrinkled face. They often have very strong protective instincts and will do just about anything for their family. With an even temper and gentle disposition, it isn’t hard to see why this dog is popular for any household. However, while the Neopolitan Mastiff may seem like an excellent family dog, it is important to remember that the they can be willful, stubborn, and even aggressive towards other people and dogs without the proper socialization.

Although the Neo is a very large and attention-grabbing breed, his bark is much larger than his bite! In fact, the Neapolitan can be considered a nearly 200 lb. lap dog! While they are definitely a protector at heart, when trained properly and socialized early, the Neo is a gentle giant who loves his family and has a very even-tempered disposition. It is important to remember that while these dogs move slowly and can be very gentle when socialized properly, they were intended to be guard dogs. Therefore, your Neo may be suspicious towards strangers, and even aggressive towards other dogs that he is not familiar with. Begin training early with your Neo and even take him to puppy kindergarten classes when he is very young in order to get him very well socialized. If you do this, you will have the opportunity to own a very gentle, loving dog that would do anything for his family and will keep you feeling safe and loved.
