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
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.

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
If Cinnamon Roll were a person, he would be a hopeless romantic. Everything about him exudes an ability for deep love. When I first met him I was struck by his warm eyes which almost distracted me from his gorgeous brindle color, which I suspect may come from some mastiff mixed in there but of course, we can’t know for sure. Now he didn’t get the size of a mastiff, he is more like a half-size. The only way I would call him a gentle-giant would be if we were talking about love and loyalty- he is a giant in that sense! Cinnamon Roll weighs 64 lbs and is full grown at an estimated 3 years old. So this is him, gorgeous, glorious him. He may be considered a big dog but he isn’t imposing at all, I don’t think he has any concept of his potential to be intimidating and I am not going to either. Let’s have him out here being a big softie in that mastiff/staffie body. Once he gets home to his forever family, he is going to bond so deeply, be prepared for a dog that looks at you with big ol’ puppy dog heart eyes! I have also heard a tiny bit of chattiness out of him while hanging out in the living room so he may also tell you he loves you sometimes. When we introduced Cinnamon to new dogs he was calm, welcoming and easy-going but isn’t super playful. He is polite and tolerant, enjoying spending time with other dogs but passing on the games of chase or wrestling that were going on around him. An ideal doggie sibling would be moderately playful but Cinnamon Roll would be just as happy soaking up all the love himself. Another dog is not necessary for him to be fulfilled and happy. A home with a yard would be great for him but isn’t necessary. He will need a bit of polishing up on his leash skills, but he is attentive and treat motivated which will make the learning process a breeze. Regular walks, treats, and sweet talk will have him walking like a dream in no-time. While Cinnamon has a calm demeanor overall, no cats in the home for him. When we introduced him to our house cat he was a bit too interested for us to say he wouldn’t try to chase the cat and given his size, that would be chaos. If you're looking for a gentle giant with lots of love to give, Cinnamon is ready to be your loyal companion.Adopt this sweet boy today and get started making beautiful memories together! ! He cannot wait to go on adventures and learn all about the world with a person of his own at the other end of the leash. We sure hope its you! If you have any questions about Cinnamon Roll or would like us to test him for a specific setting or detail, please be in touch! We can make most anything happen to ensure he is the correct fit for you and your life! Please email kristin@threelittlepittiesrescue.org with any questions.

We have over 15,000 successful adoptions so far and have excellent Google Reviews: https://g.co/kgs/UQ5Pyai We care deeply about making the perfect match between dog and family for long term success. Our rescue has a 2 acre property in Texas where we assess every animal with trainers on staff, we modify behavior as needed, and create individualized behavior plans to help prepare dogs for their future families including crate training, potty training, leash walking, etc. Our fosters are able to attend group trainings and socialization play groups to keep dogs adoption-ready. Our on-site trainers support the positive growth of our dogs and we enjoy seeing their progress! Our commitment to comprehensive medical care sets us apart. We've received glowing feedback from veterinarians who commend our dedication to ensuring the health and well-being of every animal in our care with treatments that often go above and beyond. Our adoption fees reflect the extensive care and resources that go into each animal we save. The adoption fee is a donation to the mission and goes far beyond getting a fully vetted pet. The rescue’s hard costs alone for a healthy dog to go through our program typically range between $412 to $859, which includes boarding, food, medications, vaccines, and spay/neuter. For heartworm-positive dogs, hard costs are upwards of $1,120. Additionally, dogs requiring extended boarding, extra training, or extra medical care—such as dental work, vision care, or orthopedic care—can lead to expenses running into the thousands. Also, included in the fee are costs to cover transport up to the Pacific Northwest or East Coast. While adoption fees help cover part of these expenses, we want to emphasize that Three Little Pitties Rescue is not government funded. It doesn’t stop there!

Our goal is simple— to reduce the homeless pet population through community outreach, free spay and neuter services, and by rescuing animals from the streets or overcrowded shelters where euthanasia due to lack of space is often the only option. The dog you've found online is not only lucky to be in our program, but also incredibly fortunate to have caught your eye. Thank you for considering adoption and for joining us in our mission!
