#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.

#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. â¤ï¸ 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

Meet Kip — Your Future 90-Pound Lap Dog! Looking for a best friend who gives the biggest hugs, has the sweetest heart, and thinks he's the size of a Chihuahua? Then meet Kip! Kip is a 2-year-old neutered brindle Mastiff/Pit Bull mix weighing about 88–90 pounds of pure love. Don't let his size fool you—he's the definition of a gentle giant. His favorite place in the world is wherever you are because personal space simply doesn't exist in Kip's world. He's fully potty trained, knows sit, paw, and down, and he's even working on roll over... although he usually only makes it halfway before deciding that's good enough. Kip still has that joyful puppy spirit. Sometimes he gets so excited that he gives tiny playful "love nibbles" (never aggressive), and he greets everyone like they've been best friends forever. Whether it's people or another dog, Kip's whole body wiggles with excitement when making new friends. Kip's Favorite Things: Belly rubs, scratches, and being brushed Long walks (his absolute favorite!) Tasty treats Playing with dog friends Cuddling on the couch... even if he takes up the entire couch One of Kip's cutest little quirks? He isn't a fan of walking when it's dark outside. Early evening walks and backyard potty breaks are no problem, but nighttime walks? He'd much rather wait until the sun comes back up. Kip is also wonderfully goofy. He occasionally startles himself, making everyone around him laugh. His silly personality is guaranteed to brighten even the hardest days. Because of his size and energy, Kip would thrive with a family that has a large fenced backyard where he can stretch those long legs, zoom around, and soak up the sunshine before coming inside for cuddle time. Cats are currently an unknown, but Kip does well with dogs and loves meeting new canine friends. The Perfect Home for Kip* A family ready for lots of love and cuddles* A home with a spacious yard* Someone who enjoys daily walks* Plenty of treats (he definitely won't complain!)* Bonus points if he has a dog sibling to play with! Kip's foster mom rescued him and loves him dearly. While she's nervous and excited for him to find his forever family, she would love the opportunity to remain a small part of his life through occasional updates or photos as he begins his next chapter. Kip isn't just a good dog...He's the kind of dog that changes your life.He's goofy, gentle, endlessly loving, and has the biggest heart you'll ever meet. If you've been searching for a loyal companion who will make you laugh every day, give the world's best cuddles, and love you with his whole heart. ##2803300##
