TSM[/caption]Lambeau, the St. Bernard in this video, sings along with his family on his 3rd birthday. He'd just lost his 11-year-old big brother, another St. Bernard, one week earlier.

My dog has always 'sung' along with passing first responder sirens, but never this. Wait until you see his BIG note at the end.

We've had Lambeau since he was eight weeks old, so he's spent his entire life with his big brother, Pacino. At 11-years-old, Pacino passed away from bone cancer just 6 days before this video was made .

RIP 'Big Brother' Pacino
