Do Dogs Become Vicious After Tasting Blood?

Normally, just like other animals, dogs have the natural trait of protecting and securing. From trained dogs to Guardian dogs, military dogs, and home dogs, they all have the ability to bite and in some extreme instances, kill. But they all show a level of reluctance to do so.

For some reason, many dog lovers feed their dogs lumps of raw meat with blood dripping. This does not make the dog go crazy and become vicious.
