1. The German shepherd
For a long time, this dog has been a favorite family pet. It is very tolerant and friendly towards small children, which makes it your best option if you have got kids. Weighing between 75 to 90 pounds at full maturity, the German shepherd is large, agile, and very strong. Its high level of intelligence and high degree of trainability make it perfectly suited for sentry duty, police work, danger sensing, and rescue. In addition, it is very obedient, loyal, loving, and it makes an excellent assistant for disabled people. Though it requires regular brushing, it is otherwise very easy and cheap to cater for.
2. The Rottweiler
With a history that dates back to the days of the Roman Empire, this dog is believed to be a descendant of the Italian Mastiff. It is very powerful and has a large body. At full maturity, it can weigh up to 130 pounds. Very energetic in nature, the Rottweiler can run at fast speeds for a long time. (So, intruders can hardly escape.) Also very watchful and alert, it barks at the sight of anything strange. The Rottweiler is also very friendly with people, and it interacts well with children and even other pets, such as cats. However, it can be overly aggressive towards other dogs – even with proper training and socialization.
3. The bullmastiff
The bullmastiff is very fearless and can go to any length to protect you and your family. A bulldog-mastiff cross, this dog is huge, and it uses its large size to knock down an intruder and pin him to the ground. Despite having a weight of about 120 pounds at maturity, the bullmastiff is very quick and agile. By nature, this dog is a guard, due to its size and temperament. But it must be given basic dog obedience training, as this is very essential.
4. The Komondor
Also known as the Hungarian sheepdog, this rare dog has a large body that weighs 125 pounds at full maturity. It has an unusual fur that gives it a commanding appearance. Though huge, the Komondor is very fast, agile, and powerful. In addition, it has a very strong immune system and rarely has health issues. However, this dog is easily bored, and it requires consistent training over a long time.
5. The Doberman pinscher
A very nice and docile family pet, the Doberman pinscher loves human interaction and bonds easily with people. Although it is fine with older children, this dog shouldn’t be left alone with smaller children unless it has been well trained. Muscular and athletic, the Doberman pinscher has great strength, energy, and stamina. In addition, it is determined and assertive. Though this dog is very easy to train, it requires extensive obedience training and exercise on a regular basis.
