Lost Male Dog last seen Basetdale Avenue, La Puente, CA 91746

Reported 11 months ago, updated 2 days ago

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. 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 pet'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 Costa Mesa community, the better your chances of a happy reunion!
