This is the adorable moment a dog protected his human brother from being told off by his mum.

The clip, filmed on February 1 in Northamptonshire, shows the moment Cristina taught her dog to protect her son, no matter what.

The filmer, Cristina told Newsflare: "I filmed this video because I want to show to the people how good our dog to my son when I told my dog that she needs to protect her brother(my son) and she just did it.

"Before the video was taken, I said to my dog that she needs to protect her brother(my son) and she just looks at me straight to my eyes..so when I started filming, I act like I will smack my boy and my dog was trying to stop me and she even wants to bit me just to stop me from hurting my boy..(it was just acting from my side)."

I, Cristina Castillo, age 34 I work at supermarket, I am from England UK. I filmed this video! This video was filmed last month 01/02/2020 in our house! I filmed this video because I want to show to the people how good our dog to my son, when I told my dog that she needs to protect her brother(my son) and she just did it. I have a video of their first met and you can really see that they have chemistry with each other. I am happy with my dog.very clever dog..it's like they grow up together because we got the dog when she was 8 weeks old and my son was 1 yr old. When I showed other people they were surprised about our dog's reaction,they we're amazed,and they are asking me how I train my dog, Before the video was taken,I said to my dog that she needs to protect her brother(my son) and she just look at me straight to my eyes..so when I started filming,I act like I will smack my boy and my dog was trying to stop me and she even wants to bit me just to stop me from hurting my boy..(it was just an acting from my side)
