The domestication of dogs is somewhere suspected around 12000BC. Believe it or not all dogs are descendends from the gray wolf which of course now adays is considered wild animal more then a domestuicated dog. there are really no accurate descriptions into how humans domesticated dogs but it is believed that when hunters came back to their camp and feast on the game they caught a pack of gray wolves surround the camp but never attackes the hunters and each night a small number of the pack came went in closer to the hunters where they would offer them bits of the deer or other various animals and soon afterwards they settled with the hunters leaving the former pack and becoming domesticated dogs while the other gray wolves who choose not to join would become the largest wild member of the caninae family.

Rottweiler

considered by most as a dog who would maul you to bits if given the chance but infact rottweilers have a moderate aggression in other words they are more calm then most dogs it is sometimes used for guide dog services. most rottweilers today have their tails docked [ docked been they had their tails cut off].
