Dogs treat people the way they are treated. Show them love, and they will respond positively. Treat them cruelly, and they will react to humans with fear and aggression. Let's stop blaming certain breeds for the way they have been abused by humans.
Everyday I encounter fools who believe everything they hear...and they even have a pin for it... It makes me mad when people call my chow vicious! I've grown up around dogs. ALL dogs are protective of their family & owners.
