Found small brown mixed Chihuahua-Terrier dog with red collar near Avenida del Sol in Sierra Vista.

I found a small brown dog in the park near Avenida del Sol in Sierra Vista this morning. He looks like a mix between a Chihuahua and a Terrier, with a red collar that has no tags. He seems friendly but a little scared. I couldn't find anyone around looking for him, so I took him home to keep him safe. If you recognize him or know his owner, please reach out!
