She might not be music to everybody's ears, but Miley Cyrus has just made a big difference in the life of a Rottweiler/beagle puppy she named Happy.

The country princess adopted Happy from the Saving Spot Rescue in Los Angeles earlier this week. Ever since, she has been tweeting about the adorable little pooch.

"He was left in a box in front of Walmart. I don't understand how people can be so cruel. That's why we named him Happy," she says in a Tweet explaining her new pet's background.

"I know. Happy is literally the cutest sweetest thing in the entire world! i haven't put him down since we rescued him!," she also tweeted.

Cyrus also sent out a bunch of photos of her and her new love. One of the first things the pair did together was go to the salon to get "groomed." Talk about the Hollywood treatment right off the bat!

As for her boyfriend Liam Hemsworth, he's been spotted buying dog food. We can only hope there is enough Miley to go around for him and the pup. Check out more photos of Miley and Happy below.
