Newfoundland dog wrestles tiny little girl

These two are definitely in different weight classes, but they both seem to be having the time of their lives during a wrestling match. Do you think it is a fair matchup? Samson weighs about 150 lbs while little Sierra is about 45 lbs. She sure does hold her own for a while! Samson the nanny dog still manages to be careful not to hurt her during their intense battle. So cute!
