Story
Dozer is a neutered male, black/white Mastiff Hi! I'm Dozer! I am deaf! I really don't know how to play. It’s kind of sad. I have a little routine here - I just go in my pen, eat a few bites, drink then run back out for a treat. I like being near my people & will follow you around. I am not interested in playing ball. I really just don't know what to do with myself other than just enjoy life. I am so sweet, according to my foster. So if you don't mind a good-sized velcro dog, I'm your guy! ##2498995##

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!!

Story
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. If you are interested in me, please fill out an application on our website! www.ipawditforward.org

Story
Howdy there, I’m Chuckles. I’m a 4 year old, 80 lb. Mastiff mix with a big heart, a bigger frame, and a personality that just needs a minute to shine. I can be a little nervous when I first meet new people or find myself in new situations. I like to take things in slowly at first, make sure everything feels safe, and confirm you are not secretly a broom or a suspicious moving object. Once I realize you are kind and safe, I come out of my shell pretty quickly, especially if you have treats. Snacks are basically my love language. A few good treats and suddenly I am your best friend, emotional support giant, and personal shadow all rolled into one. I am a very sweet boy who loves affection from my people. I enjoy leaning in for pets, hanging out close by, and being part of whatever is going on. I may be large, but I have a very soft heart and I am happiest when I am near my humans. I also enjoy going on walks and adventures, taking in the world at a steady, thoughtful pace while I sniff everything that might possibly be important. I do well with other dogs and enjoy their company. As for cats, I have lived with a cat before and did well. I would do best with kids over the age of 6 who understand that I may need a little space when I am first adjusting or feeling unsure. Once I settle in, I am affectionate, goofy, and deeply loyal, but I appreciate people who let me warm up at my own pace. So if all of this sounds amazing to you, please come and meet me! My adoption fee is $295 and I'm neutered, vaccinated and microchipped. Apply to meet me today!

Story
Due to unfortunate circumstances we need to rehome our Saint Bernard asap. Murphy is a 3 years old Saint Bernard Great Pyrenees mix and needs lots of space to run and play. We currently have a little over two acres and it’s still not enough space for him. He gets along with cats and kids but can be very picky when it comes to dogs he likes, especially if they are not fixed. He needs slow and controlled introductions to other dogs but eventually warms up and loves to play. I would recommend an experienced individual with large breeds as he can get hyper and can be protective over those he loves. Spring is not his favorite season as he does tend to get reoccurring ear infections due to allergies. Once he is comfortable he is an absolute lover and will try to lay on your lap if you let him. He loves belly rubs and giving you lots of slobbery kisses.
