Story
Hi there, I’m Sarge!I’m a big, beefy bundle of love with an even bigger heart. I am looking for a forever home for my golden years. I would probably do best in a home without other dogs so we can decompress and settle in. I’ve been through a lot recently after losing my owner, and I`m ready to start a new chapter with a loving person or family.I’m a super sweet guy who loves getting scratches and attention. One of my favorite things to do is carry my bed and toys around—it’s kind of my signature move! I both have so much love to give, and I`d be so happy to share it with you.If you’re looking for love and companionship, I’d love to meet you.

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
Finn may look like a rockstar with his striking Mastiff–Shepherd good looks, but at heart, he’s a big, soft lovebug. Weighing in at about 60 pounds, Finn has grown into a handsome boy with a beautiful gray and tan coat, soulful eyes, and an even bigger personality. Despite his star-quality appearance, Finn is more of a laid-back, easygoing guy—think Eeyore vibes, but with engines revved and ready to love. From the moment he wakes up, he’s prepared to shower his people with affection… and trust us, it’s A LOT of love! Finn does well with other dogs and does need a slow, proper introductions to new friends—both two-legged and four-legged. Once he knows you, he loves you deeply. He’s happiest when he has a buddy (human or canine) to share his world with. Affection is Finn’s specialty. When someone comes to greet him, he lights up, runs over with enthusiasm, and hands out slobbery kisses and big hugs like they’re backstage passes. His joy is genuine, his heart is huge, and he’s always thrilled to see his people. If you’re looking for a big, lovable, slightly goofy rockstar who will adore you endlessly, Finn is ready to take center stage in your heart. Local adoption only $200 (in TX)

Story
Hi, I’m Luke, and I’m a big, lovable boy tipping the scales at just over 100 lbs! Don’t let my size fool you—I’m a happy, easygoing pup who just wants to play, explore, and cuddle. I’m all about the good things in life: squeaky toys, water play, long walks, and best of all—snuggle time on the couch. I’m a pro at giving hugs (though I’m working on not jumping up too hard to give them—oops!). I get along great with other dogs and kids, but because of my size and enthusiasm, I’d do best with older children who won’t get accidentally knocked over during playtime. I’m crate trained, housebroken, and walk nicely on a leash—unless there’s a squirrel… then it’s game on! I do have a slight prey drive, so a little guidance goes a long way. If you’re looking for a big-hearted, playful companion to fill your home with love (and maybe take up some space on your couch), I’m your guy. Let’s make forever happen! 🐾 Local adoption fee is $200(in TX) Out of state adoption fee is $450 (includes transport to your area)

Story
Meet Ruby! Ruby came to WAG with a bang — rescued from a house fire as a tiny pup, this Mastiff mix brought every bit of that flame with her. Bold, spirited, and full of personality, Ruby is equal parts mischief and love. She'll make you laugh, keep you on your toes, and melt your heart all in the same afternoon. Ruby is ready to grow into an incredible companion — with the right foundation. Her dream home includes a safely fenced yard to burn off energy, patient humans committed to consistent training, and older kids (age 5+) who can match her bold spirit. WAG will provide all age-appropriate vaccinations, but it will be the responsibility of the adopter to have Ruby spayed at the age recommended by her vet. Visit our website to fill out an Adoption Application http://www.wagsequimwa.com If you have any questions, please email: office@wagsequimwa.com. Most of our dogs require a fully fenced yard, this does depend on the individual dogs needs and safety requirements. Adoption donation fee up to $350 (Please understand this adoption donation goes towards helping all the dogs we rescue) June 15, 2026, 12:05 pm

Story
FOSTER OR FOREVER HOME NEEDED! Say hello to Tiger! He is a loving and sweet ~3yo, ~90lb Mastiff/Shepherd mix who is ready to find his forever home. He came to us as a stray from a high kill shelter in CA. Tiger is a wonderful boy and has a great demeanor. He is super loving with everyone he meets and very gentle. He walks wonderful on leash and will make a great dog for his forever family! He has been good with other dogs in our care. We think he would do just fine with kids, but he is not tested with cats. Tiger is neutered, UTD on shots and microchipped. His adoption fee is $450.
