Story
Meet Ruby! Ruby came to WAG after being rescued from a house fire as a young puppy, and she has grown into a joyful adolescent with plenty of personality. She's playful, curious, and genuinely loves spending time with people. Whether she's learning, playing, or joining you for an adventure, Ruby is eager to participate in all the things! Ruby has lots of fun adolescent energy and would thrive with an engaged family that can provide regular activity, and continued reward-based training. She enjoys learning and responds beautifully when training feels positive and rewarding. Ruby currently shares her space with a canine roommate, so she may be able to live with another well-matched dog following thoughtful introductions. A securely fenced yard would give her a safe place to play and explore, and a home with children age 5 or older would likely be the best fit for her enthusiastic personality. Ruby is already spayed, vaccinated, and ready to begin her next chapter. She cant wait to meet you! 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) September 3, 2026, 12:51 pm

Good with dogs, Spayed or Neutered,
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 $300 (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 $300(in TX) Out of state adoption fee is $550 (includes transport to your area)

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.
