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.

Story

***NOTE: This pet is currently at the shelter in Republic, WA, and can be delivered to an approved adopter on our 4/11/26 adopted pet transport to Monroe, WA to begin a 30-day trial placement – part of our distance adoption program.*** Considering adopting? The first step is to complete our online Adoption Application at http://forgetmenotshelter.org/application Please do not call the shelter; do the application first. Meet Boudica, a spirited and affectionate young female (born 8/23/25) with a heart full of joy and a motor that just won't stop! This adorable Bernese/Mastiff mix (possibly with a little Rhodesian Ridgeback in the stew) absolutely lives for playtime, specifically the high-octane thrill of chasing after a ball, making her the perfect partner for an active owner who loves engaging with their pup. When she is not busy on the field, Boudica is a certified cuddlebug who adores receiving behind-the-ear scratches, leaning into you for affection. To keep her busy during downtime, she loves gnawing on nice cow bones, which she treats as her ultimate treasure. While she is full of confidence during playtime, Boudica can be a little skittish when encountering new or loud noises, a typical trait for a previously socially isolated pup still learning about the world. However, she has shown incredible resilience and has acclimated wonderfully since arriving at the shelter, proving she is quick to learn and eager to feel secure. She has a very high puppy energy level and would thrive in a home that can keep up with her playfulness. Regarding her feline friends, she is exceptionally interested in kitties and is not cat-aggressive; because of her intense puppy curiosity and energy, she will require a home that can facilitate slow, structured introductions to cats to ensure everyone gets along. She does well with other dogs, and should adapt well to calm children. Boudica currently weighs about 50# and is housetrained. She is currently learning about leash walking and will need continued training in that area post-adoption. If you are looking for a loyal, energetic, and loving companion to join your adventures, Boudica is ready for you. All pets arrive spayed/neutered, dewormed, microchipped and vaccinated. Adoption fee for Boudica is a suggested minimum of $150 (more gratefully accepted). All pets are placed with a 30-day money-back trial period, to give pet and family enough time to discover any unknown allergies or other conflicts. Can't come to Republic? Don't let that stop you! We have monthly transports to the Seattle area, delivering adopted pets to their new owners. If you can add a little to your donation to help us cover our volunteer driver's expenses, that would be great!

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

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)
