Will my dog turn on me?

This is funny! No way will your st. bernard turn on you. I too saw the Chimp who turned into a "brutal murderer". Chimps actually are becoming more and more aggressive, which is why people tend to stay away from zoo's and wildlife activity including hunting. Dogs are different however. Dogs are "mans best friends" like you've preobably heard. Dogs usually only want to please their owner, unless they've been abused, or you've given them a reason to. Chimpanzees, with a genetic profile that's 98 percent like ours, can seem like cute, hairy iterations of people. But periodic violent attacks on humans, including one in Havilah, Calif., in 2005 in which a man was maimed by two chimps at an animal sanctuary, are reminders that the animals have at least one big difference: brute strength. Chimps do not have the sophistication like "house" pets do. They do not realize it HURTS us. They think they are after food. Now many wildlifers are trying to captivate the chimps. Your st. bernard is a loyal friend of yours. He's been around you for a long time to know your daily routine, if he had wanted to hurt you, he would've done it by now! I own 5 Golden Retrievers that I rescued, I would know. Thanks for reading my comment!
