Cerberus is an amazing 2yr old. He's very well behaved and loves children and people. He is playful, energetic, loving( he thinks he a lap puppy, lol). The only reason im looking to rehome him is because recently I found out that im highly allergic to dogs😢. Any questions feel free to ask.

Story
Hi! My name is Banana and I am available for adoption.I was brought in by a good Samaritan on April 09, 2026.I weigh 108lbs and am considered a `large breed` dog.I am an affectionate lovebug who would be thrilled to play with you at home!I am full of energy and I love to play! I tend to calm down more when the people around me stay calm. I do best when I have lots of exercise and something to keep my mind busy.I would do best in a home with older children.I am a spirited dog with a fun-loving personality! I am still working on my manners, so I would do best with a family who is willing to work with me and help me become the best dog I can be!

Story
Looking for a good home preferably with a fenced yard. Can be off leash and will follow you around. She was originally a farm dog, used to other animals and people, great around horses. Looking for a home with people who would give her lots of love and attention. She is great with people and kids. Very much so a couch potato. She is the sweetest girl. I hope for a family who loves her as much as we do.

Story
Meet Striker! 👑 Striker is a handsome adolescent large-breed mix with a heart just as big as his paws. This playful guy is full of life and always ready for his next adventure—whether that’s romping around the yard, chasing toys, or making new canine friends. Striker is wonderfully dog-social and truly thrives when he has a buddy to play with. He loves a good game of chase and would be thrilled to join a home with another playful dog or regular opportunities for doggy playdates. Like many young pups, Striker is still learning the ropes, but he’s eager to please and ready to grow into an amazing companion with a little guidance and consistency. His joyful energy and affectionate nature make him a fantastic match for an active household that can keep up with his zest for life. If you’re looking for a fun-loving, loyal companion who will bring excitement, laughter, and lots of tail wags into your home, Striker might just be your perfect match! 🐾

Eloise

Mastiff

Female, Young
Rochester, WA
Size
(when grown) X-Large 101 lbs (46 kg) or more
Details
Not good with cats, Needs experienced adopter, House-trained,
Story
Eloise is a good dog. Loyal and kind. She does not like strangers and takes time to warm up. She does not do well with cats. She is our only dog and it is unknown if she does well with other dogs. She did take time to warm up to my families dog at their ranch. But eventually did. She needs to be on acreage without dogs on the other side of the fence. She is fence reactive. (Responds to electric wire) She would be the perfect only pet for someone out in the country. Or with a larger yard with good training. Eloise is slow to warm up, but once she does, you will have her heart forever. She loves to snuggle, and spend her days laying in the sun.
