FOSTER OR FOREVER HOME NEEDED! Say hello to Tiger! He is a loving and sweet ~3yo, ~90lb Mastiff/Shepherd mix who is ready to find his forever home. He came to us as a stray from a high kill shelter in CA. Tiger is a wonderful boy and has a great demeanor. He is super loving with everyone he meets and very gentle. He walks wonderful on leash and will make a great dog for his forever family! He has been good with other dogs in our care. We think he would do just fine with kids, but he is not tested with cats. Tiger is neutered, UTD on shots and microchipped. His adoption fee is $450.

Story
FOSTER OR FOREVER HOME NEEDED Introducing this humongous boy, Fasa! Fasa (short for Mufasa) is a 3.5-year-old, 170 LB Boerboel who came to us as a stray from an overcrowded shelter in CA hoping to find an amazing forever home here in WA! Fasa is very charming, sweet, and extremely strong. He will require an adopter that can handle his strength and has large breed experience. We are also looking for a standalone home with a yard outside of the city as he would not do well as a city dog. He is very loving and will be an incredibly loyal companion to whoever adopts him, but he will require a strong leader who will set the proper boundaries he needs to maintain his good temperament and keep him well exposed and socialized. He has done well with other dogs in our care and would do well with another dog in the home, preferably a female. He would also do just fine as an only dog where he can soak up all the love and attention! Fasa is a beautiful boy with a lot of love to give and will make an amazing companion to whoever adopts him! He is UTD on vaccinations, microchipped, and neutered. His adoption fee $500.

Duvall, WA
Size
(when grown) X-Large 101 lbs (46 kg) or more
Details
Not good with kids, Not good with dogs, Not good with cats, Needs experienced adopter, House-trained, Spayed or Neutered, Shots are up-to-date,
Story
Boogie is a sweet, loving, and loyal Boerboel (South African Mastiff) mix who just turned 7 and weighs 130 pounds. He neutered and up-to-date on vaccines. He would thrive in a home with a confident, experienced owner who doesn’t have young children. Boogie is happiest when he’s surrounded by his people, whether it’s cuddling on the couch or relaxing in the sun outside. He prefers to be the only dog in the home - expectations include laid-back female dogs. This gentle giant is a bit of a couch potato and doesn't need to be walked frequently, making him a low-energy companion. He loves to stay close to his owners (he’s a true Velcro dog!) and is always up for a good cuddle. He’s also a fan of digging, rolling around, and lounging in the dirt, so a secure fence is a must. Boogie loves to sleep by his owner's side, snoring on his back with his big feet in the air. While he may experience some separation anxiety at times, with patience and a gentle routine, he'll quickly adjust and settle

Story
Meet Finn the Rockstar! Finn is a silly and great boy and looks like a rockstar with his appearance (being a mix of Blackmouth Cur and Shepherd breeds). Finn has grown into a big boy, weighing in at a whopping 60 pounds, he's a nice medium sized dog with a huge personality. He has a beautiful gray and tan coat and gentle, kind eyes. Overall, Finn is a great dog. He gets along with everyone, with proper introductions, and loves his people deeply. He's always good with dogs, having siblings is always a great social starter for most dogs. Based on Finn's interactions with everyone he would really do well with slow and proper introductions with anyone he meets. He might be a rockstar but he just rolls like that. Finn is laidback lovebug, kinda eyore-like, easygoing and slow. From the moment Finn wakes up he is ready and engines roarin' to show anyone how much love he has, it's A LOT OF LOVE!He is also VERY affectionate, anytime someone goes to great Finn he just loves to run up to them and give them a slobbering of kisses and a big hug. He's always so happy to see people and genuinely shows it! Local adoption fee is $200 (in TX)
