Thousands of years ago, dogs were domesticated to provide companionship and protection to mankind. Some dogs have instincts to protect their people and territory from all sorts of danger. They make excellent guard dogs and are known for their loyalty, fearlessness, and strength.
Jaguars are one of the most furious predators with a bite force of 1,500 PSI, as mentioned by BBC Science Focus. They can attack livestock and even humans. Guard dogs can help defend against these large predators. There are three types of guard dogs:
Watchdogs: Watchdogs are similar to guard dogs, but they are not very aggressive. They bark to alert their owners of intruders, but do not attack.
Protection Dogs: These breeds can be trained to act on commands, like police dogs.
Guard Dogs: They have strong protective instincts and can bite or attack.
Have a look at these 7 large guard dog breeds for protection against jaguars.
