Post on our local group: Lost and Found Pets Altadena-Pasadena- South Pasadena, CA, NextDoor. Let Pasadena Humane know. Tips for Lost Dogs Leave some articles of your unwashed clothing (socks, shoes, t-shirt, pillowcases, etc.) and his/her bed outside for him/her to smell home. Leave a gate open for him/her. If microchipped, notify the chip company that he/she is missing; update/confirm your contact info. Post on NextDoor, Ring and local Lost & Found Pets groups for your area. Ask neighbors to check their cameras. Please contact either of these legit pet rescue/recovery specialists: -Mike Noon of CatchingPaws -Babs Fry of San Fernando Valley - SFV Lost and Found Pets Both will give you instructions on how to get him/her home. Post signs - a minimum of 50 in at least a 2-mile radius. Put “Do Not Chase” on them and ask for sightings, but beware of scammers claiming to have your dog. Visit surrounding shelters in person daily - leave flyers there. Leave flyers at surrounding vet offices/ER vets where someone may take him/her for a chip scan. Best wishes that he/she is home soon. If you see him/her while out driving, open your car door and let him/her jump in on their own. Bring smelly treats (hot dogs, pieces of rotisserie chicken), so that if you see him/her while out, you can sit on the ground quietly, Not facing your dog - and gently toss the treats near them, tossing them closer to you each time. Have a leash or slip lead ready to put on them while they’re eating. He/she’ll will spook easily while out on the run. Best wishes!
