A funny video has emerged of a dog protecting her new born babies from her owner.

The footage, shot earlier this year at a home near Toronto, Canada, shows Tilly attacking her owner's finger as he tries to touch one of her puppies.

"She was such a good mommy to her babies so I did give her the space she wanted," the filmer wrote online.

"As soon as Tilly's baby grew up she became my best friend once again."

This is Tilly. She is at my side all the time and i usually can't have her lose site of me or she panics. I love her dearly. The thing is once tilly had babies that all changed and her nice doggie personality changed drastically. lol, She would NOT let anyone touch her babies!! She would always eat out of my hand in the past but as soon as her babies were born i couldn't feed her like that anymore. I had to slide her food on a dish too her and run away or she would attack me. lol She was such a good mommy to her babies so i did give her the space she wanted. As soon as Tillys baby grew up she became my best friend once again!!
