This loyal pet gives a new definition to the phrase ‘guard dog’ as he watches over his pregnant owner and attacks her boyfriend any time he tries to lay a hand on her baby bump.

Video footage shows the woman’s partner trying to get close to her but being warned off by the dog – referred to in the video as Tebow — as he barks, stands on two legs and bites to keep him away.

The video uploader wrote that Tebow, a pit bull-boxer mix, has ‘become extremely protective of the yet to be delivered bundle of joy’ and noted that the dog hasn’t been trained to watch over the unborn baby.
