Story
Hi there, I’m Sarge!I’m a big, beefy bundle of love with an even bigger heart. My best friend Wyatt and I are a bonded pair, which means we’re looking for a forever home where we can stay together. We would probably do best in a home without other dogs so we can decompress and settle in. We’ve been through a lot recently after losing our owner, and we’re 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! Wyatt and I both have so much love to give, and we’d be so happy to share it with you.If you’re looking for double the love and companionship, we’d love to meet you.

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 Red! Red may have escaped the flames of the house fire he experienced as a young puppy, but this Mastiff mix pup prefers to take his time before turning up the heat with new people. Red came to us a bit shy, but he's growing into a fun and confident companion. A toy fanatic and people-pleaser at heart, Red thrives when given the chance to learn and show off his skills. He's the student who always does his homework — patient handlers willing to invest in training will be richly rewarded. Red's ideal home includes a safely fenced yard, owners dedicated to consistent training, and children over age 5. WAG will provide age-appropriate vaccinations for Red, but it will be the responsibility of the adopter to have Red neutered at his vet's recommended age. 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) May 29, 2026, 1:12 pm

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.

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.
