A pit bull-boxer mix named Tebow is the ultimate guard dog to a pregnant woman's belly.
A video shows a woman's boyfriend reaching to touch her pregnant belly, but the dog won' let him get near her. Tebow was barking, standing on two legs and even nipping at the man in attempts to protect his owner.
The video uploader, who is a friend of the boyfriend, wrote that Tebow started acting this way on his own once his owner became pregnant.
"The dog is not vicious and is not a danger to anyone," the uploader wrote. "He simply has decided no one should be messing with that belly!"
Dogs pay close attention to their owners and can pick up changes in a woman's body language and a change in the attitude of others toward her when she becomes pregnant, reported Mail Online. During this time dogs can become more protective of their owners - even towards the baby's father.
