Story
Meet Marvel, Your New Best Friend! Marvel is a 3 year old Mastiff mix who is looking for his furever home. He is a gentle giant who was found wandering during a thunderstorm, seeking safety and comfort. While we don't know much about where Marvel came from, we do know that he arrived with a heart of gold and a massive smile that is sure to melt your heart. Marvel loves to play with other dogs and is always down for snuggles and a good chew toy, making him the perfect cuddle buddy after a long day. Marvel is crate trained and housebroken. He knows basic commands, but can get a little excited when meeting someone new-he might just jump up for a hug! His friendly nature makes every introduction a joyful occasion. Marvel loves to go for walks and is good in the car. He gets along great with other dogs and even smaller animals like cats and chickens! He's always ready to make new friends and share his love with everyone.

Story
MEET GOLDIE, a beautiful & young Mastiff in need of a foster or forever home! Goldie is a 1-year-old girl and is still a big puppy! She already weighs 90 pounds, and will likely put on weight as she grows up. She was rescued from an overcrowded California shelter. Goldie is a sweet, gentle dog. She is slightly shy, especially with men, but very affectionate once she gets to know you. She gives big kisses! We do not know too much yet about how she is with other dogs, because she caught a doggy cough at the shelter so has been in isolation. But given her gentleness, we are expecting she will be good with other dogs, and we will test her soon. She would do well with a single person, a couple or a family with older kids. Please email for an application.

Story
FOSTER OR FOREVER HOME NEEDED: Introducing Max! He is a 3-year-old, 84lb French Mastiff mix who came to us from an overcrowded shelter in CA. Max is one big sweetheart! He walks well on a leash, gets along great with other dogs, and is friendly with everyone he meets. He does well being groomed and loves any attention he can get from his people. He will require an adopter that is able to handle his strength as he does like to pull occasionally when he sees something of interest, and he is very strong when doing so. He is a gentle giant but is strong, so due to his strength, we are looking for an adult only household or a household with children over 10 years. Max has a great smile, charming brown eyes, and so much love to give! He is going to be a loyal companion to whoever adopts him. Max is UTD on vaccinations, microchipped, and neutered. His adoption fee is $450.

Story
Duke is such a good boy. I rescued him from Texas in June. I sent him to a three week training Boot Camp and he did really well. Unfortunately, with my schedule I am unable to give him all of the attention that he needs. He loves to run and play at the dog park. Gets along great with all the dogs. He does have separation anxiety, which may stem from events that happened prior to me adopting him. I feel he would be best suited in a house where someone is home and also a very large fenced yard so he can run at his leisure.

Story
This is so tough, but we are needing to rehome our English Mastiff, Percy. He will be 7 years old Jan/2025. We are located in the Gig Harbor/Port Orchard area of Washington. We were hoping to find him a home locally so we could remain in touch, but have not had much luck so far. This is not an emergency, so we are willing to wait and find the perfect home for him. Percy is a sweet & super lovable giant who thinks he is a lap dog. He is fully potty trained & crate trained, although he has not been in a crate for a couple years now. Instead, he has a big bed that is his "place" and he knows that command, as well as other basic commands. He needs to be in a home with no other pets and ideally no children, although tweens/teenagers would be ok. He can resource guard sometimes and needs to be cared for by people who understand this and manage it by not putting him in a situation to resource guard in the first place. Experienced Mastiff and/or resource guard experience highly preferred.
