We interrupt our regular Monday “Sleeping Dogs” feature to present some singing dogs.

For your Christmas Eve enjoyment, here are Crooning Cody and Singing Sierra, who have appeared here before, and also once made it on Anderson Cooper’s show.

They belong to Adam Yamada-Hanff, a friend of mine in Baltimore and proprietor of the website singingdogs.net.

“I have started to record a few special and unique versions of classic Christmas songs,” Adam informs me. “We are still working on a couple currently but we decided to start off with the well known classic, ‘Rudolph the Rednose Reindeer’ since that was requested via email by a fan of the singing dogs.

“While I was playing the song I started laughing, since it was just too funny not to laugh! Even after playing with Cody and Sierra for awhile it is still very hard not to laugh when they are both singing loudly together.”

Here they are performing “Oh Christmas Tree”:

Adam and  his family work with the National English Shepherd Rescue, Ltd.

As for our sleeping dogs, they’ll return next Monday.

Since we’ve shown you the musical stylings of the world famous Adam Yamada-Hanffff and his dogs, Sierra and Cody, a few times, it’s only fair we give some space to this relative newcomer to the field, some guy named Kiefer Sutherland.

Sutherland posted a video on Twitter of his dog singing along as he played guitar, along with the comment, “Even the dog can sing better than me.”

The actor, who’s now starring in the TV series, Touch, didn’t bother to mention his dog’s name in the post.

In case you missed it, here are Adam Yamada-Hanff and his singing dogs — well, one sang anyway — in their appearance Monday on Anderson Cooper’s show.

Sierra belted out “Auld Lang Syne” as Adam played saxophone and Cody, whose a little newer to the act, checked out the audience.

Here, as promised, is Adam Yamada-Hanff’s big news: He and his singing dogs, Sierra and Cody, will be on the Anderson Cooper show.

Adam tells me the segment was taped last week and is scheduled to air Monday.

They’ll be performing Auld Lang Syne, one of their earlier renditions of which is shown above.

Adam said one of the program’s producers called him last week, asking him to come on the show with both dogs. She told him she’d been searching YouTube for interesting New Year’s videos when she came across Sierra and Cody.

“We think they’re hilarious!” he quoted her as saying. “We would love to have you on the show. We just thought it would be perfect for our New Year’s special …”

Adam said they drove to New York last Wednesday for the Thursday taping. Both dogs sang during a rehearsal, as they generally do when he starts playing the saxophone. But when the crew asked him to perform it again, for a sound check, neither dog uttered a sound.

“Sierra just lay on the floor and had a look as to say, ‘We just did this!’”

Adam said he was a little nervous they might not perform when the time came, and he didn’t divulge how the final performance went.

“Watch Monday,” he said.

The show airs in Baltimore at 2 p.m on WBAL. To find when and where it airs in your part of the country, click here.

Surely, you remember Sierra and Cody.

Who better to turn to for a saxophone-accompanied Christmas Eve carol?

We met Sierra and her human, Adam Yamada-Hanff, a Baltimore area community college student, back in May of 2010, when he agreed to perform with Sierra during my “Hey, That’s My Dog!” photo exhibit at Captain Larry’s in Baltimore.

Adam later brought his other dog, Cody, in on the act, and they’ve posted several videos on YouTube.

When he’s not playing saxophone and performing with his dogs, Adam writes about automobiles for several websites, and has his own blog called Adam’s Auto Advice.

Adam’s goal is to use the dogs’ performances to raise money for animal shelters and rescue organizations.

He also has some big news to share, but we’re going to make you tune in tomorrow — and get serenaded again — to find out.

The Kennedy family says Tucker, their one and a half year old Schnoodle, plays the piano and sings along at least 3 or 4 times every day, but, despite all the practice, doesn’t seem to be getting any better.

Apparently, the public enjoys the pooch’s musical stylings: In only a month on YouTube, the Tucker video has garnered near a million views.

Singing Sierra is back, and just in time for Christmas.

Adam Yamada-Hanff, a Baltimore area community college student, has posted several videos on YouTube of Sierra “singing” as he plays his saxophone. This latest one also features Cody, who clearly considers himself a backkground vocalist.

We met Sierra and Adam back in May, when they — well, Adam, anyway — agreed to a quick sidewalk performance during my “Hey, That’s My Dog!” photo exhibit at Captain Larry’s, a bar and restaurant on Fort Avenue in South Baltimore.

Adam uses Sierra’s singing abilities to help raise money for animal shelters and rescue organizations.

Granted, you can find plenty of singing dogs on YouTube. Granted, not all of them appear to be enjoying their performance. And granted, not all of them are ready for American Idol.

But Sierra, shown here with her rendition of “Love Me Tender,” is a dog that “really likes to sing” — especially this particular song, according to her owner, Adam Yamada-Hanff, a 21-year-old community college student. (That’s him on saxophone.)

Besides, she’s a Baltimore dog.

There are some songs Sierra doesn’t like (“Sierra is a Doggie Diva!” Adam says). But “Love Me Tender” is one of her favorites, and Adam’s.

“The lyrics are very fitting for dogs,” he said.

Sierra is an English Shepherd, almost 2 years old. Adam is trying to figure out a way to use her singing talents to help out animal shelters and rescue groups. “A singing dog will definitely encourage some donations,” he said.

Adam grew up with a dog named Roger — that’s them to the left –  a stray that, though he died several years ago, Adam and his family still think about often.

Why some dogs react the way they do to certain songs and sounds would probably make for an interesting scientific study.

Until then, we have YouTube, where a mounting number of videos, it has been noted, show dogs howling along with — or in objection to — the theme from “Law & Order.”

It’s not the first time multiple dog owners have noticed certain songs seem to cause their pets to vocalize, and captured the result on video. Remember all those videos of dogs singing along with Gwen Stefani’s ”Sweet Escape?”

Just as only some dogs howl at sirens, some howl at Gwen Stefani and, for reasons just as mysterious, at the Law & Order theme. Whether they are expressing discomfort or joining the chorus, we don’t really know.

In any event, for an impressive array of dogs howling at “Law & Order,” check out the compilation video above, or visit nastynets.com.

Kelly Reeves at the website Urlesque believes she has stumbled upon dogs’ favorite song: It’s “The Sweet Escape,” by Gwen Stefani, featuring Akon, who sings the “woo-woos.”

Stefani’s 2007 single, “appears to be the favorite song of dogs across the world,” she says “From Huskies to Dachshunds, something about the ‘woooo wooooos’ in the tune cut to to the core of pooches, leading them to tilt their heads in wonder and sing along with Gwen and Akon.”

She presents as evidence not two, or even five, but 11 Youtube videos of dogs singing along with the song and reports that — wouldn’t you just know it — that’s only the tip of the iceberg.

You can see the entire compilation at Urlesque.com.

Some of the dogs seem to have the tune down better than others, and I got woo-wooed out by around number six. But, no doubt, you would like to see at least one more.
