The relationship between a parent and their kid is strong. Parents do almost anything in their power to keep their children safe. They go through hell and back just to see a smile on their little faces. And if someone threatens their kids, they immediately get offensive. This is true for humans as well as animals. Just take a look at this video for example.
Krystal Berry was at the Paynes Prairie Preserve State Park when she saw a herd of horses grazing peacefully. But then a large alligator tried to attack a baby horse. Fearing for the safety of his herd, a big black stallion quickly jumped forward to put the alligator back to his place. Park officials checked the animals involved in the scuffle and reported that none of them were bleeding or showing any signs of injury.
