Mui Mui Female Dog

LOST PawBoost ID: 73307151


Montclair, CA 91763

LOST DOG — PLEASE HELP 🐶 Name: MuiMui Breed: Teddy (Toy Poodle) Age: 1 year old, female Size: About 15 lbs Color: Yellow / light golden MuiMui ran away from our home near Vernon Ave & Shirley Ave montclair ca 91763 on Saturday, August 23, 2026, around 4:00 PM. Her AirTag last showed her on Sunday, August 24 at about 11:00 AM on Monte Vista Ave montclair , near Easterseals Southern California. When I got there, the AirTag was already on the ground at the edge of the sidewalk on Monte Vista Ave — so she is no longer being tracked and could be anywhere in that area. She should still be wearing her collar with my phone number on it. She is small, friendly, and may be scared — please don’t chase her. If you see her, try calling her name gently or offer food, and call me right away. Please call or text: Any sighting helps, even if you’re not able to catch her. Please share this post — thank you so much. 🙏

Frequently Asked Questions

I lost my dog. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost dog to PawBoost in no time flat. We'll send an email alert to our local members, post to the PawBoost-powered Facebook page for your area, add your dog to our lost & found, and make a lost dog flyer – all for free.

Other sites that help you raise local awareness for your lost dog with minimal time and effort are Nextdoor.com – a PawBoost partner – and Craigslist. Both of these sites have very active lost & found sections mainly used for lost pets. We highly recommend you use these resources in addition to PawBoost!

Visit your local shelters and animal control agencies in person. Details can get lost in translation over the phone and that might lead to missed connection.

If chipped, make sure your dog's microchip is registered and up to date. If you don't know your pet's chip manufacturer or number, your vet should be able to help locate this information.

Put up flyers and tell your neighbors to be on the lookout. The more you engage the Upland community, the better your chances of a happy reunion!
