This big boy is looking for some big love! Meet Frito! Frito is a stoutly gentleman who is a staff and volunteer favorite at Pasadena Humane. He is a 3-year-old Mastiff mix who loves to spend his days right by your side, whether that’s strolling through the neighborhood, playing in the yard or the pool, or enjoying some serious nap time. He also knows several training cues like “sit” and “paw” and loves to full-body lean into you for some good pets. Frito is also Adoption Trial eligible, so if you’d like to see how Frito can fit into your home for a couple of days, an adoption trial is a great way to do just that. Who knows, you may just fall in love with this handsome boy.

Ace Ventura has 3 years experience working as a pet detective. His specialty is investigating anything fun to do or tasty to eat! You can follow along with his current investigations on Facebook at @AdoptAceVentura Ace is a dog-friendly, happy-go-lucky dude with the personality that matches Joey from Friends combined with Jim Carrey from the Ace Ventura, Pet Detective movies! He will keep you entertained and laughing! Ace loves road trips and outings but most of all he LOVES to snuggle and play with you or other dogs. And hugging things, whether it be a pillow, a toy or your arm. While at 80lbs, he's a bit of a bull in a china shop, but he's very well-behaved and a polite house guest.

Good with kids, Good with dogs, House-trained, Shots are up-to-date,

Story

Mister is a gentle giant with the sweetest, most easygoing personality. My father has raised him since birth & lovingly trained him to be an obedient, hilarious, lovable spirit. He got his name as a puppy because he always looked so serious, like a little old man deep in thought. Mister is happiest with simple things: affection, a little attention, & a cozy spot to relax. He loves children, & we’ve recently discovered he enjoys playing with even small dogs! Heartbreakingly, my father is facing serious, life-threatening health issues & will be hospitalized for some time. If my father does recover, he will need to live in a nursing facility. My partner and I have three small dogs in an apartment, & unfortunately, our landlord cannot accommodate Mister. We’re devastated to have to find Mister a new family. We’re desperately hoping to find him a safe, stable, loving home with enough space for a dog his size. Mister deserves a wonderful family & home who will cherish him as much as we have.

Story

Meet WILLOW—a big, beautiful girl with an even bigger heart! 💚 At about a year and a half old, this Mastiff/Cane Corso mix loves to hike, run, and splash in the ocean. She adores children, is affectionate with people, and does very well with other dogs. WILLOW gave birth to 12 puppies and lovingly raised 11. Every one of those 11 pups has found a home. Now this wonderful mama is ready for a forever family of her own. WILLOW is about 105 pounds and still filling out, so her family should be ready for a truly big dog. We don’t yet know how she is with cats, and a cat-free home would be the best fit. If you’re looking for a loyal companion for walks, water adventures, and lots of love, WILLOW would love to meet you. 🐾 Available for adoption through START Rescue in Southern California.

Story

#A5801178 Meet Ozzy , an almost 1.5-year-old German Shepherd / Saint Bernard mix and one seriously striking XL boy! This unusual mix has given him the most gorgeous cinnamon-and-honey coloring, accented by deeper brown around his ears and snoot, and his laid-back personality is just as lovable as his looks. Ozzy is calm, happy, and mellow, and he’s wonderful on leash - as long as you’re willing to let this curious boy stop for all the sniffs and explore his surroundings, because his walks may take a little longer! He prefers his people to other dogs and bonds closely with his favorite humans, showing the kind of unwavering loyalty that makes him a devoted companion; he’d ideally love being your one-and-only, but could potentially share his home with a calm canine who respects his boundaries. â¤ï¸ Already potty trained and familiar with the basics like sit and paw, Ozzy is a smart, well-mannered boy with plenty of potential to learn even more with the right motivation! Come take home this all-around superstar today and you’ll be rewarded with the best furever companion -1 year 4 month German Shepherd / Saint Bernard mix -84 pound neutered male -may need the standard round of shots and preventatives before he can go home with you, but the shelter can likely help with this! -came to the Baldwin Park Animal Care Center on 9/18/26 as an internal transfer from another shelter - but poor Ozzy was originally surrendered due to owner problems, not by any fault of his own -cool and calm, he is super attentive and a breeze to handle, even given his size! -loves to sniff around and explore, just wants to stop and soak in all of life’s little wonders - he’ll open your eyes to them too! -a people person more than a dog’s dog, Ozzy wants nothing more than to be the center of your attention, and he will work hard to earn it, especially by showing off his smarts! OZZY’S VIDEO: https://www.youtube.com/shorts/IXD_FEdux8I For more information, contact volunteer Lisa at lisaa@unitedhopeforanimals.org ---- Look up this or other animals at Baldwin Park Animal Care Center https://animalcare.lacounty.gov/view-our-animals/ Use their unique ID NUMBER.
