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

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. Don't let his initial shyness fool you — once Red decides you've earned his trust, you've gained a loyal, loving companion for life. 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.

Details

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 $200 (in TX)

Good with kids, Good with dogs, Not good with cats, Spayed or Neutered,

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)

Ralph BW

Mastiff Mixed Breed (Large)

Male, 1 yr 2 mos

Everett, WA

Size

(when grown) Large 61-100 lbs (28-45 kg)

Good with kids, Good with dogs, Good with cats, Spayed or Neutered,

Story

Ralph the Derp! Ralph is a huge friendly, enthusiastic, uncoordinated 4-legged energetic goofball! He was rescued from “death row” at a high kill shelter, as a skinny stray with a treatable skin condition. His fur has almost completely grown in & he is now at a healthy weight. This overgrown mastiff/Cane Corso mix pup has no comprehension of his size, leaning into humans for affection or trying to ooze onto laps for cuddles. He is being trained not to jump and not to paw for attention/affection/play because he currently has 85# of mass behind those “congenial” moves. Ralph plays well with dogs of all sizes, but would do best with med-to-larger dogs due to his size & poorly curbed gusto. He hordes toys, taking them all to his chosen dog bed of the day. He likes to carry a special toy “baby” in his mouth when going out in the yard. He does need to be fed in his crate & will guard his empty food bowl from other dogs, unless he is distracted with a toy & led outdoors after meals. He is great on a leash, makes awesome grunty sounds when cuddled, enjoys baths. Ralph will make a great addition to an active family with older children. He is eager to please, food and affection oriented (although a bit stubborn at times), making him an ideal candidate for success with continuation of his training. Please consider adopting the gorgeous big derp into your home. Attributes: In training to avoid jumping/pawing Active family He is neutered, microchipped, had recent cherry eye repair and up to date on all vaccines and preventions. Local adoption fee is $200(in TX) Out of state adoption fee is $450 (includes transport to your area)
