Story
Hi, I'm Freya! I'm a sweet mama and came with my 9 puppies. I'm a very good girl. I'm said to have had a few litters in the past and I'm ready to put motherhood behind me and have a little time for myself. Won't you spend it with me? If you're interested in adopting me, please fill out an application at www.polkcountyhumanesociety.org/adopt. You can also reserve an appointment to meet me. Some pets are in foster homes or may already have visits scheduled, so appointments help ensure I’ll be available. Polk County Humane Society is located in Bolivar, Missouri, and we welcome adopters from any state. We have access to a transport to Aurora, CO. Other out of state adopters either travel to Missouri or arrange & pay for air transport. Virtual meet and greets are available on the appointment request. ##2755149##

Story
I am need of help rehoming Margie Mae. Long story, short version. I was awarded her in a divorce and have tried to keep her but I have no back yard. I mention this because we have to take her potty out front and she wants to defend our house and because of this she has gone after our neighbor’s dog. It’s weird because this is the only place that she acts like this. She adores all people and all dogs. She is fine at the dog park. Other places. Anywhere. Just not in front of our house. We’ve tried training and she is on medication for the anxiety. She is fixed and up to date with her shots. She is almost 6. She is ridiculously sweet 99% of the time. Her tail is always wagging. Just really want to find her a place where she can be calm and comfortable. She is a good girl. Happy to answer any questions. I am in Cottleville, MO Thank you in advance. $50 Rehoming fee. She just needs a good home.

Story
Hi, I’m Luke, and I’m a big, lovable boy tipping the scales at just over 100 lbs! Don’t let my size fool you—I’m a happy, easygoing pup who just wants to play, explore, and cuddle. I’m all about the good things in life: squeaky toys, water play, long walks, and best of all—snuggle time on the couch. I’m a pro at giving hugs (though I’m working on not jumping up too hard to give them—oops!). I get along great with other dogs and kids, but because of my size and enthusiasm, I’d do best with older children who won’t get accidentally knocked over during playtime. I’m crate trained, housebroken, and walk nicely on a leash—unless there’s a squirrel… then it’s game on! I do have a slight prey drive, so a little guidance goes a long way. If you’re looking for a big-hearted, playful companion to fill your home with love (and maybe take up some space on your couch), I’m your guy. Let’s make forever happen! 🐾 Local adoption fee is $300(in TX) Out of state adoption fee is $550 (includes transport to your area)

Story
Finn may look like a rockstar with his striking Mastiff–Shepherd good looks, but at heart, he’s a big, soft lovebug. Weighing in at about 60 pounds, Finn has grown into a handsome boy with a beautiful gray and tan coat, soulful eyes, and an even bigger personality. Despite his star-quality appearance, Finn is more of a laid-back, easygoing guy—think Eeyore vibes, but with engines revved and ready to love. From the moment he wakes up, he’s prepared to shower his people with affection… and trust us, it’s A LOT of love! Finn does well with other dogs and does need a slow, proper introductions to new friends—both two-legged and four-legged. Once he knows you, he loves you deeply. He’s happiest when he has a buddy (human or canine) to share his world with. Affection is Finn’s specialty. When someone comes to greet him, he lights up, runs over with enthusiasm, and hands out slobbery kisses and big hugs like they’re backstage passes. His joy is genuine, his heart is huge, and he’s always thrilled to see his people. If you’re looking for a big, lovable, slightly goofy rockstar who will adore you endlessly, Finn is ready to take center stage in your heart. Local adoption only $300 (in TX)

Story
🌪️✨ Meet Twister! ✨🌪️ Twister is a very sweet, friendly dog with tons of excitement and energy! He loves getting outside and is always ready for his next adventure. Twister is an extremely strong puller and will need a confident, physically capable handler who can continue working on his leash manners. He is also reactive toward other dogs, so he would do best with plenty of space from other animals and an experienced adopter who understands how to manage his needs. Underneath all that strength and excitement is a very nice boy who is ready for someone patient enough to help him succeed!

Story
✨ Meet Zaffre! ✨ Zaffre is a 5-year-old mastiff/pit mix weighing about 85 lbs of pure love and goofiness. He’s been with us for about two weeks, and he has truly been the best house guest. When we met Zaffre at the shelter, he had only been there a couple of days after coming from a neglected situation with 7 other dogs. Despite his rough start, Zaffre has settled into home life beautifully and continues to show just how special he is. 🏡 In the home: • About 90% potty trained (a few marking accidents in our unfinished basement) • Great with our female GSD • Tolerates our two cats • Treat motivated with no signs of food aggression 🐕 Personality & training: Zaffre is a big, goofy lug with the sweetest soul. He’s curious and clearly experiencing many things for the first time, taking it all in with wide-eyed wonder. Because he’s a big boy, he can pull on the leash when he really needs to go, but he responds well to correction and wants to do the right thing. ✂️ Health: Zaffre was neutered last Friday and is recovering very well. Zaffre deserves a loving, patient forever home where he can continue to learn, feel safe, and be cherished. If you’re looking for a loyal companion with a gentle heart and a silly side, Zaffre just might be your perfect match. 💙
