Story
How this pet arrived:Astrid was brought in by their previous owner on June 3, 2026. Why this pet is the one for you: Astrid is a sweet and friendly dog looking for a loving home. According to her owner, she is a social companion who loves to play with other dogs and has previously done well living with both cats and children. Astrid also knows basic commands like "sit" and "stay," which highlights her bright personality. Since she can sometimes show some arousal and impulsivity when she's excited, she would benefit from a family that can offer her a structured routine and healthy outlets for her enthusiasm. Astrid flourishes in an environment that provides plenty of companionship, interactive play, and the steady guidance she needs to be her best self. She is ready to become a loyal and fun-loving member of her new family. At SDHS:Astrid has been vaccinated, microchipped and spayed. Astrid is now ready for adoption!

Story
Meet Octavia also called Tavi. Octavia is a big girl with an even bigger heart. Since being rescued from the shelter, she’s proven herself to be the perfect houseguest—gentle, loving, and so grateful for a second chance. Affectionately known as Tavi, she’s ready to leave her past behind and find a forever home where she can truly shine. She just needs someone to give her that chance… and we know she’ll give a lifetime of love in return. Due to Tavi's neglect, she had a severe eye infection when we rescued her from the shelter on the euth list.  Unfortunately, we were unable to save her eye but that doesn't stop her one bit! ##2688495##

Story
WE ARE COURTESY POSTING THIS DOG FOR THE MORENO VALLEY ANIMAL SHELTER TO HELP THEM FIND A HOME. The shelter is severely overcrowded and desperately needs help finding adopters. Dogs are being turned in higher numbers than the shelter can accommodate; therefore, many are losing their lives simply due to a lack of cage space. We are helping get the word out about their immediate need. Please save this deserving pooch and clear a kennel for another dog in need today! This beautiful dog is located in the Moreno Valley shelter. The shelter needs to clear kennels. They are over capacity, and all available dogs are in urgent need. Please visit or email the shelter directly to adopt. PACO - ID#A551355 Shelter staff named me PACO, and I am a neutered male, brown and black Mastiff. The shelter thinks I am about 1 year and 6 months old. I weigh approximately 70.60 lbs. SEE MORE VIDEOS AND PHOTOS HERE: https://myalbum.com/album/XM6PgGQr5fuPAr/ STAFF NOTES: * Paco knows sit and shake * Paco appears to be potty trained * Paco loves toys * Paco enjoys sharing a kennel with a spayed Chinese Sharpei mix (Ariel A551354); they prefer to eat separately Moreno Valley Animal Shelter 14041 Elsworth Street, Moreno Valley, CA 92553 951-413-3790 Adoption hours: Tuesday - Friday 10 am - 5 pm Saturday 10:30 am - 3:30 pm Closed Sunday-Monday & Holidays

Story
How Awesome Sauce arrived:Awesome Sauce was brought in by our Humane Law Enforcement team on April 19, 2026. Why Awesome Sauce is the one for you:Meet Awesome Sauce, a big, lovable goofball who lives up to his name with a personality that is equal parts heart and hype. From the moment you meet him, he brings a whole lot of flavor to the table with his wiggly body, soft eyes and signature tail that whips with excitement when he sees his people. He bonds quickly and thrives on attention, always ready to soak up pets or stick close by your side. He walks well for the most part and enjoys sniffing and exploring, though he can get a bit amped up during transitions, such as leaving or returning to his kennel. When he's excited, he may jump or get a little mouthy, but he is already showing improvement and responds well to redirection and clear guidance. He does have a few medical considerations to keep in mind, including sun-related skin growths on his belly, an inward-rolling eyelid and a small growth on his chin that will need observation over time. This big boy will do best with an adopter who can help him continue working on his manners and give him outlets for his energy, along with plenty of companionship. If you're looking for a dog with a big personality, a bigger heart and just the right amount of zest, Awesome Sauce is ready to spice up your life. Please bring a leash & collar when adopting. At SDHS:Awesome Sauce has been vaccinated, microchipped and neutered.Excitable Dog: This pet requires a virtual behavior consult, please watch THIS video to learn more about them.
