Lost Terrier Mix in Nashville: Help Find Her!

Little female terrier mix ran away from her sitter (see map) while we were out of the country. She had her pink ID tag on, but we wouldn’t have received any calls. After over a month, we are desperate to find her. She’s 14 pounds and 8 years old. Smooth fur - dark brown and medium brown with white underneath. Her build is very spindly and delicate. Her tail is long and curls under her stomach when she’s afraid. Timid at first. Please don’t chase her.
