'He's Studying Opera': Service Dog Sings Along to TV in Adorable Video

Anyone with a pet will tell you that animals often develop funny habits, from an obsession with french fries to loving being tucked in at bedtime.

Lin Parkin's dog is no exception, as her service dog Sam loves to sing along to television commercials.

Parkin lives on the East Coast of Florida and when her husband unexpectedly died four years ago, she knew she wanted to search for a puppy.

She told Newsweek: "A year later I'm checking the shelters and come across an adorable puppy at a foster home."

When she arrived to meet the dog, the foster home had four puppies and Parkin jumped at the chance to meet them: "Of course, the one I had planned to bring home prances out, totally ignoring me," she said: "Two more skitter in and one of the puppies comes to me and plops down on my foot and refuses to move."

She instantly knew that Sam was the dog for her, and he came home with her. Because of some hearing and mobility issues, he is also a service dog for his loving owner.

"Lately I've lost my balance and there was Sam, standing by me and helping me get up," said Parkin: "He also let me know when the doorbell rang—and when anyone walked by," she laughed: "He seemed like a natural helper so I hired a service dog trainer and am constantly working on making him the best service dog ever."

Sam's singing antics started when he was less than a year old and first heard the commercial for MyPillow.

"He's studying opera," joked Parkin who says that Sam never misses an opportunity to share a tune: "When he hears one of the commercials, he will sing from whatever room he is in. He's sang in front of the TV, upside down on the couch... wherever he is."

The American Kennel Club (AKC) says that when our canine friends howl along to sounds, we've got their ancestors to thank.

"One reason for howling is the modern dog's connection to his ancestor, the wolf. In the wild, wolves howl to communicate with one another. They do it to let other pack members know where they are or to warn off other animals encroaching on their territory," the AKC says.

Also known to howl to assert group identity—explaining the domino effect in the neighborhood when one dog starts to howl and others follow suit—this behavior is deeply buried in a dog's genetic code.

Research also suggests that dogs may have favorite tunes, just like us. Psychologist Deborah Wells exposed shelter dogs to different types of music and monitored their responses.

Trying a mix of tunes from Beethoven to Britney Spears, Wells discovered that dogs' reactions differ with the genres.

While heavy metal caused pets to exhibit more stress and unease, classical music would lead them to stop barking and even help them settle.
