Story
Dozer is a neutered male, black/white Mastiff Hi! I'm Dozer! I am deaf! I really don't know how to play. It’s kind of sad. I have a little routine here - I just go in my pen, eat a few bites, drink then run back out for a treat. I like being near my people & will follow you around. I am not interested in playing ball. I really just don't know what to do with myself other than just enjoy life. I am so sweet, according to my foster. So if you don't mind a good-sized velcro dog, I'm your guy! ##2498995##

Story
Introducing Rose — the 4‑month‑old Mastiff mix who survived a fire and came out the other side with even more spark! This girl is pure energy, pure fun, and pure “let’s do EVERYTHING.” Her back is still healing, but her personality? Fully unleashed. Rose is a total snack‑motivated genius, making training a blast. She’s playful, adventurous, and always ready to be the life of the party… but don’t let her firecracker energy fool you. After a day of exploring, and being her bold little self, Rose is all about a long, cozy snuggle. She melts right into you like she was born for it. If you want a pup who will keep you laughing, keep you moving, and then curl up for the sweetest cuddle session, Rose is your perfect match. She’s bold. She’s bright. She’s beautiful. And she’s ready for her forever home. Visit our website to fill out an Adoption Application http://www.wagsequimwa.com If you have any questions, please email: office@wagsequimwa.com. Most of our dogs require a fully fenced yard, this does depend on the individual dogs needs and safety requirements. Adoption donation fee up to $350 (Please understand this adoption donation goes towards helping all the dogs we rescue) May 16, 2026, 4:34 pm
