Story
FOSTER OR FOREVER HOME NEEDED: Meet Orion! He is ~7-8 year-old Bullmastiff/Boerboel mix who weighs 120lbs. He came to us from an overcrowded shelter in CA and has been waiting for his forever home with us for 3 years! His perfect home would have a chill, steady, and peaceful environment. Orion walks well on a leash but can be strong and will need a family with good dog-handling skills. He is crate trained and finds comfort in a regular routine. Breed experience is required for his adopter. This big guy is looking for a quieter forever home outside of city-life. He will need a single-family detached home in a suburban or rural neighborhood. He would LOVE a large, securely fenced yard as well to roam and be with his people. In the summertime he would enjoy laying around in the sun! He can be dog selective and has shown to be friendly with submissive females but would do best as an only dog soaking up all the attention! Orion is neutered, up to date on vaccinations, and microchipped. His adoption fee is $400.

These pups are in Monroe, Washington too!

Story
***NOTE: This pet is currently at the shelter in Republic, WA, and can be delivered to an approved adopter on our 5/2/26 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, but not with small humans. 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!
