Story
#A5798082 Say hello to Melly , a 4 year old spayed Mastiff Mix who is ready to come home and be your couch buddy! This precious dog was taken in to Baldwin Park Animal Care Center as a transfer and would like to find her forever home soon. Melly is the most patient gentle giant who would love to spend her time getting cuddles, going on walks, and getting all the yummy treats! She is a little overweight and could lose 10 pounds to feel her best, but she would love to spend all her time with you after her exercise! Melly has the most beautiful dark stripe brindle and a gorgeous complementing white chest. In her household she would love a mellow vibe to fit her energy levels as well as calmer dogs that she can relax with. Melly is pretty good on leash, shows signs of housebreaking, and works for treats to learn other commands in addition to sit! If you’re looking for a big cuddly giant to accompany your relaxation, Melly might just be the perfect addition to your home!   -4 year old Mastiff Mix with white chest -Spayed female, 114 lbs. -Couch potato and gentle giant girl -Knows sit and will work for treats -Has mellow energy level and likes calm dogs -Pretty good on leash and will enjoy neighborhood walks with cuddles after -Dark stripe brindle   MELLY’S VIDEO: https://www.youtube.com/shorts/FGgcOdgh9sE   For more information, contact volunteer Lisa at lisaa@unitedhopeforanimals.org Photo Credit: Rafael Diaz   ---- Look up this or other animals at Baldwin Park Animal Care Center https://animalcare.lacounty.gov/view-our-animals/    Use their unique ID NUMBER.

Story
#A5798971 Meet Bullwinkle , a 6-year-old Mastiff mix boy with the most perfectly smooshable, adorably wrinkled face, just begging for kisses, and a megawatt smile guaranteed to brighten your day! A little extra chonky and wonderfully squishy, this sweetheart is practically made for cozy cuddles and snuggling up with his favorite people. Sadly surrendered when his family decided they had “no time” for him anymore, Bullwinkle has been waiting at the shelter for a while now, making tons of friends with staff and volunteers who have fallen in love with his adoring personality and perfect manners. ❤️ His one request is to be king of your castle - he prefers people over other pets and would love to be your one-and-only, soaking up all the attention for himself! Already a well-mannered gentleman, Bullwinkle is good on leash, potty trained, mellow, and even knows tricks like sit and paw, making him a wonderfully easy companion for all kinds of homes and families. Come meet this lovable wrinkle muffin and show him that he’ll never have to wonder if he’s worth making time for again!   -6 year old tan Mastiff mix  -98 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 9/3/26 as an owner surrender, as they allegedly had “no time” for him anymore -staff and volunteer favorite - he’s made fast friends with anyone and everyone! -would do best as a solo dog, soaking up all your attention and affection by himself -very good, well trained boy - great on leash, potty trained, mellow energy level, and knows some trick - will show off some moves like sit and paw, and takes treats with a polite, gentle mouth   BULLWINKLE’S VIDEO: https://www.youtube.com/shorts/LK0p_WU9-qo   For more information, contact volunteer Lisa at lisaa@unitedhopeforanimals.org Photo Credit: Rafael Diaz   ---- Look up this or other animals at Baldwin Park Animal Care Center https://animalcare.lacounty.gov/view-our-animals/    Use their unique ID NUMBER.

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.
