Dog is definitely (wo)man's best friend.

Just look at the pure joy from this 13-year-old golden retriever, Buddy, who is simply over the moon when her owner, Hannah Foraker, returned from basic training in the Army in Oklahoma over the holidays.

Buddy has arthritis and has lost the bulk of her hearing, but seeing Foraker injected her with an enthusiasm not seen in some time.

We opened the front door and she came running out and greeted me and my family, but then kind of did a double take and came back to me. She was completely overwhelmed and she couldn’t even stand up."

Foraker said her return home turned Buddy into a totally different dog. "She normally has trouble going up and down the stairs and takes shorter walks, but now that I was home she was so happy and active," she said. "She would get up and do her happy dance."

Dance away, Buddy.
