Story
Meet Lady Rose— the Queen of Cuddles and Couch Time! 👑 If you’re looking for the world’s sweetest, most smooshable, big-headed lovebug… you’ve found her! Lady is a 3-year-old mastiff mix with the softest soul and the cutest little white “shoes” you’ve ever seen. She’s equal parts gentle couch potato and goofy best friend — basically a perfect mix of chill and charm. Lady LOVES her people and will happily lean right into you for snuggles, belly rubs, or just to remind you that she’s there. She’s the kind of dog who rolls over for pets, politely asks for more, and then melts into your lap (yes, she’s convinced she’s lap-sized). She has perfected the art of leaning her whole body into you just to make sure you know she loves you. She’s not pushy about it either — she’ll politely ask for affection, and when you stop, she gives you the saddest “but why did you stop petting me?” look until your heart melts and you start again. She loves to roll over for belly rubs, and if she could, she’d spend all day like that. Watch Lady Rose in action in her video! https://youtu.be/CrIBB0RQicA?si=iQAFu6ekTYtBx0sT This big girl is a total dream on leash — she walks right beside you like she’s done it a million times before, checking in often with a little look that says, “Am I doing good?” (Spoiler: she’s always doing good.) She’s super easy to handle and loves meeting new people. In fact, she’s never met a stranger — she walks right up to everyone she meets, wiggles, leans in for pets, and wins hearts instantly. Lady is also amazing with kiddos — she knows to be extra gentle, doesn’t jump, and melts when little hands reach for her. She’s the kind of dog that makes people say, “Wow, she’s such a good girl,” about ten times in a row. When it comes to other dogs, Lady has what we call “queen energy.” She’s calm, polite, and a little bit aloof — she doesn’t need to be the center of the dog party, but she’ll happily hang out in the same space as long as everyone’s being respectful. She’s met a few dogs in playgroups and usually prefers to wander around and mind her business (unless someone gets a little too bouncy in her face — then she’ll give them a tiny “hey, personal space please” and go back to her stroll). She’d do best with another laid-back, mellow dog who won’t pester her for playtime — or she’d be perfectly happy being the only royalty in the house! And let’s talk about kitties — Lady met one and was a total lady about it! She was curious but cautious, gave a sniff or two, and then politely backed off when the kitty didn’t seem interested. She’s got great manners and would do just fine sharing her castle with a feline friend who appreciates her calm energy. At home, Lady is pure cozy vibes. She’s low-energy and would rather nap next to you than run around. She’s the ultimate couch potato. She’s all about comfort, love, and being close to her people. Lady would do amazing in a home or apartment with someone who wants a snuggle buddy, walking companion, and best friend all rolled into one big, sweet, smooshy face. She’s affectionate, gentle, and ready to fill your life with calm, goofy joy. So if you’ve been dreaming of a big-headed, soft-hearted, nap-loving, people-adoring, kid-snuggling, dog-tolerating, cat-respecting queen to rule your heart, Lady Rose is your gal!!

Meet Dozer – Your Oversized Lap Dog! If you're looking for a gentle giant with a goofy personality, Dozer is your guy. This handsome Mastiff weighs in at around 100 pounds, but he's convinced he's the perfect size to curl up in your lap—and honestly, who are we to tell him otherwise? Dozer is deaf, but don't let that fool you. He's incredibly people-oriented, eager to connect, and quickly learns through hand signals, patience, and plenty of treats. In fact, he's highly treat motivated, making training both fun and rewarding. He's a lovable goofball who doesn't always know what to do with all those long legs, which only adds to his charm. While he can be a little awkward at times, he's not anxious—just a big, silly boy figuring life out one step at a time. Dozer enjoys the company of other dogs, adores people, and has a sweet, gentle nature that makes everyone fall in love with him. He's already neutered and ready to find a family that will appreciate his unique personality and endless affection. If you've been dreaming of a loyal best friend with a heart as big as his paws, Dozer is waiting to meet you. ##2498995##

Believe in second chances! I'm Buddha boy, a shining star waiting to sparkle in my forever home! 🌟 I'm a people person and a loyal companion. At my age I prefer to be an only pet. 🙏 On a leash, I'm a rockstar! I thrive on walks and can't resist a game of fetch. And, for my age, I'm still agile and full of life! 💪 I love going "bye bye" in the car to head for walks! I am a great car rider! My ideal home would be one that is quiet and allows me to just be the special dog that I am. One that doesn't have a lot of traffic in/out. I take time to warm up to new people and would prefer a home where I was not bombarded with new things all the time. I thrive on consistency. 🐾 Please note: no small pets, cats, or dogs, as my instincts might get the better of me.

Meet Norman – Your Gentle Giant Companion 🐾 Norman is a 6.5-year-old Saint Bernard with a big heart to match his big paws. This handsome boy can be an absolute love bug once he feels comfortable and bonded with his people. He enjoys affection, lounging nearby, and being a loyal presence in the home. He does not do well with younger kids and is not good with other dogs either. He prefers the cold so AC is needed! Norman has a history of mild hip dysplasia and will need ongoing dental maintenance to keep him healthy which he has with his transferrable insurance for $112/month. This insurance covers all of his health care needs for no additional costs other than the monthly payment. Why Norman? If you're looking for a devoted companion who will reward your patience with deep loyalty and affection, Norman is the perfect match. He’s a gentle sensitive giant who just needs the right home and unfortunately, we have to re-home him with two little infants in the home.

Meet Bo Breed: Belgian Malinois / Mastiff Mix Sex: Male DOB: August 3, 2022 Weight: 70 Pounds Health: Healthy and doing well Bo is a handsome, intelligent boy with a big heart and an even bigger personality. This energetic Malinois/Mastiff mix combines the loyalty and devotion of both breeds with a playful spirit that makes every day feel like an adventure. Sadly, Bo has become one of the rescue’s long-timers, patiently watching other dogs leave for their forever homes while he continues to wait for someone to notice him. He deserves the chance to finally leave the shelter behind and start the life he’s been hoping for. Personality Bo is affectionate, loyal, and full of joyful energy. He loves interacting with people and thrives on connection and companionship. His playful personality keeps life fun, whether he’s enjoying a walk, learning something new, or simply spending time close to his humans. Bo forms strong bonds and becomes deeply devoted to the people he trusts. His sweet nature and loving heart make him a wonderful companion who truly wants to be part of a family. Breed Info A Belgian Malinois and Mastiff mix combines intelligence, strength, and loyalty. Malinois are known for their sharp minds, trainability, and desire to work closely with their owners, while Mastiffs bring calm confidence and deep devotion to their families. Dogs with this mix tend to be incredibly loyal and thrive when given both mental stimulation and physical activity. With structure and engagement, they become deeply bonded companions who love being involved in daily life. Owner Responsibilities Bo already has a foundation of basic training, but like many intelligent dogs, he will benefit from continued training and mental enrichment. Regular exercise such as daily walks, play sessions, and activities that challenge his mind will help keep him happy and balanced. Positive reinforcement training will strengthen the bond between Bo and his adopter while helping him continue to grow into a confident, well-mannered companion. ⚠️ Things to Consider Before adopting Bo, it’s important to think about your long-term lifestyle and stability. Are pets allowed where you live now and in the future? If you move, will Bo move with you? Do you have the time each day to provide exercise, engagement, and companionship? Are you financially prepared for routine veterinary care, food, and unexpected medical needs? Dogs like Bo deserve a home that is committed to them for life. Vet Care Even though Bo is healthy, adopters should establish care with their own veterinarian soon after adoption. This helps ensure preventative care continues properly and provides a trusted medical partner for Bo’s long-term health and well-being. Understanding the 3-3-3 Rule Like most rescue dogs, Bo will need time to adjust to his new home. The first 3 days he may feel unsure as he decompresses from the transition. The first 3 weeks he will begin learning your routine and feeling more secure. By 3 months, his confidence will grow and his full personality will shine. Patience and consistency during this adjustment period will help Bo thrive. Why Bo? Bo has waited patiently for someone to see the amazing dog he truly is. He is loyal, playful, intelligent, and full of love to give. Long-timer dogs like Bo often become the most devoted companions because they know what it means to finally be chosen. The family who gives Bo his forever home will gain a faithful friend who will stand by their side through every adventure. Adoption Information If you are interested in adopting this wonderful dog, please complete an adoption application by visiting: https://www.ozzieandfriendsrescue.org/adoptions Thank you for considering adoption through Ozzie and Friends Rescue, a Los Angeles–based rescue dedicated to giving dogs a second chance at a loving home. Our team carefully reviews every application and will reach out to help match you with the right dog for your home and lifestyle. You may be seeing our dogs listed in your state because we work hard to give as many of our rescue dogs as possible the opportunity to be seen by loving families beyond our local area. While we are based in Los Angeles, we expand our reach throughout the Western United States and the Midwest to help more dogs find the forever homes they deserve. We understand that transportation and adoption fees can sometimes feel like a big commitment, and we truly appreciate every person who considers opening their heart and home to a rescue dog. Our goal is simply to give these dogs the best chance at being seen, adopted, and loved. Ozzie and Friends Rescue coordinates safe and reliable transport so adopted dogs can travel to their new homes across the Western United States, Canada, and the Midwest. We can’t wait to help you meet your next fur-ever best friend. July 31, 2026, 12:03 pm

Story
Sporty Spots is a very handsome Saint Bernard American Bulldog mix that weighs about 80 pounds! He absolutely loves people and loves to get attention and belly rubs! He will sit with his head in your lap getting all the head scratches for hours if you let him. He is a goofball and is sure to make you laugh and smile everyday.  Spots is a super friendly and outgoing dog. He is good with children that are aged 14 and over! He loves toys, and he also loves to play in water. He is the kind of dog that would love to play in the sprinklers and have his own little pool he can play in. He really loves to play with balls, he will chase them all day. Spots would do best in a home that has a backyard for him to run around in.  Spots does well with some dogs that are his size or larger. Spots will need to go to a home that has a strong handler and has owned large dogs before. So far, he has learned to sit, stay, and lay down.  Overall, Spots is an amazing dog that is waiting for his forever home. He is very loyal and very friendly with other people. He also is very protective of his home and loves to keep patrol of his yard! He loves toys and water and would make the perfect travel buddy!
