Tori Spelling frantically searches for missing dog

Tori Spelling is frantically searching for her dog Mitzi after the 6-pound pup went missing on Sept. 15 from Calabasas, California.

Spelling wrote on Instagram, "Pls HELP... Our Family Dog MITZI has gone missing! Spread the word."

Spelling added that the situation is even more urgent because Mitzi needs medication. Though Mitzi has a collar on, it currently has the wrong information.

Mitzi is a white long-haired terrier mix with brown markings on her face. Spelling wrote that though the dog barks, she does not bite, and she is microchipped.

Spelling asked fans to spread the word by using hashtag #MitziMissing, and wrote that if anyone comes forward with information, they will be rewarded with no questions asked.

Spelling urged users with info to e-mail mitzimissing@gmail.com.
