Dorian is a gray, black, tan tabby mix cat with a fluffy tail. I last saw him really early in the morning on 10/31. He is a very friendly, cuddly, senior that takes twice daily and ocassiaonally leaves my patio. Let me know if he's crashing with you....or if there has been any sign of him.

LOST PawBoost ID: 70144693
Mission Viejo, CA 92691
Misty is sweet, lovable and smart. She has no tail, multi-color female with green eyes, white chest and belly, and 4 white paws. A little smudge of dark fur on the right of her nose. Affectionate but cautious, has been strictly an indoor cat. We believe Misty got out the day of the hse fire and is out in the neighborhood. Please call if she's found.

Little Boy Male Dog
LOST PawBoost ID: 69525687
Santa Fe Springs, CA 90670
He has a slim build with a long torso, has black and white fur with light brown legs, and has not been neutered yet. He was last seen wearing a navy blue collar with a metal clasp. He’s pretty shy and timid but very sweet. It’s unfortunately been over 3 years now since that photo was taken so his hair should be considerably longer now. Thank you for any and all continued efforts in his search. He is still dearly missed.

Goofy Boy Male Dog
LOST PawBoost ID: 72226194
La Puente, CA 91746
All white, fluffy, feathery fur. He has bent ears and a showy, plumy tail He holds high over his back. He squints his right eye quite a bit from being born with entropion rolling eyelids, though he underwent surgery, he still will squint at times. He has dark eyes. He has pink and black gums. He is neutered and received his other vaccinations via original owner. He also has his Rabies vaccine which is good until April 11, 2026. This pup is not aggressive , but aloof and not highly sociable, more wary. He is still a baby . He has his personality from his parentage. Tibetan Mastiff and American Akita. He is comfortable with people that know him and the dogs he grew with. Due to his size , he may appear scary and his eyes are noticeable but he is less than a year old and not a threat. He had just been adopted out with his sister Helena and broke out just about the next day of his new residence. He is microchipped. I am hoping he is safe and his new owner is searching around through local areas for him as well. He was found by someone on Facebook , but he left. If anyone sees him, please call Animal Control. He is microchipped and he will be reunited via this way. He most likely will not go with anyone willingly, but he has been gone for some time. I am hoping he is not hurt or dead.

Frequently Asked Questions
I lost my pet. What should I do?
Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost pet 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 pet to our lost & found, and make a lost pet flyer – all for free.
Other sites that help you raise local awareness for your lost pet with minimal time and effort are Nextdoor.com – a PawBoost partner – and Craigslist.
