Atom and Humber have even appeared in television adverts and on billboards in Santiago, and Alexis explained how he chose the names for his superstar dogs.
“Atom is one of the characters in a movie called Real Steel,” the 27-year-old told Arsenal Player. “Atom the robot is very old and apparently useless but when he starts fighting he beats the best robots in the world. I like the movie so much that I thought I would call my first dog Atom.
“My other dog Humber reminds me of my brother Humberto. My brother is a very sweet guy, just like Humber is. Both of them enjoy staying home or watching football on TV. That’s why I decided to call my other dog Humber.
“I just had the idea of creating an Instagram account for them so people could follow what they do,” Alexis said. "The thing is both became famous in Chile after starring in Master Dog's advert.
“I upload videos or pictures to their accounts whenever I can and I even saw their pictures on billboards when I went to Chile. They were smiling for the advert - what great acting! It really made me laugh.”
