One of the most touching moments in a mother's life is when she hears her baby say "mama" for the first time.
In a video posted to YouTube in June, Andrea Diaz-Giovanini is seen using food to coax her son Sam into saying that sweet word. But instead, her Australian Shepherd dog Patches steps up and says it. Sam clearly isn't happy about that.
It's not the only time that Patches has said "mama." A separate video posted in late June shows him receiving a reward from his owners.
