Story
I'm Mia. I'm a good girl. I'm only 2 years old and my person just can't care for me any more. So, I need a new one. I'm hoping I will find my soulmate that I can spend the rest of my life loving. Is it you? If you're interested in adopting me, fill out an adoption application online at www.polkcountyhumanesociety.org/adopt where you will also find a link to reserve me for an appointment. Some pets are in foster homes or may already have an appointment scheduled, so the appointment is important to make sure I will be available to meet you when you come. Polk County Humane Society is located in Bolivar, Missouri, but also makes transports to the Denver, CO, Des Moines, IA and St. Louis areas twice monthly. For potential adopters in those areas, we can do a virtual visit using FaceTime or another app. Just request an appointment using the same link, but note that you want the visit to be virtual. We will call you at the time of the visit once it is confirmed. For long distance transports to Colorado and Iowa, there is an additional $100 fee to cover the cost of the transport ($65) and a health certificate from a veterinarian ($35). For transports to St. Louis, the additional fee is $50 to help cover gas. Going that last mile home for our sweet pets! All of our pets are neutered or spayed, have vaccinations appropriate for their age, treated with flea/tick/heartworm prevention, dewormed and dogs are also microchipped. #adoptdontshop ##2810304##

Story
Meet Sabrina, a gentle 6-year-old Mastiff mix who’s in need of a special forever home. Sabrina is living with mast cell tumors (MCT) due to cancer and is currently on medication to keep her as comfortable as possible. She requires a loving home that is prepared to offer her hospice care and a peaceful environment. Sabrina can be shy with new people and may give a warning growl or snap if approached when she’s not ready. However, once she builds trust, she becomes deeply affectionate and very attached to her people. She gets along well with mellow dogs and will thrive in a calm household where she can feel safe and loved. If you have a compassionate heart and are ready to provide a supportive and caring home for a special dog like Sabrina, you’ll find a loyal and loving companion in her.

Story
Mylo is an amazing dog, super friendly and easy going. Somewhat lazy but loves to play fetch from time to time or roam a field. He’s old and hard of hearing but great with all people and pets. He’s a tad overly friendly but likes to snooze most of the day. He still has lots of life to live and has been pretty pampered most of his life ! He Loves being near the kids and action of the day. Since relocating to a state with more sun he’s found a love for sunbathing. His one true love is open space and snowballs when available. He’s been an amazing part of our family but our current dynamic is not what’s best for him or our family sadly.

Story
We have had Nala since she was 8weeks old! She is now 5 will be 6 December 22nd! She is a cuddle bug for sure and loves to play! shes very smart and learns quickly. She is kennel trained, house trained and knows basic commands. She loves her paw held. She will literally be your best friend. She needs an active loving family. I have developed an allergy to her fur and while i have been able to manage it pretty well our work situation is also changing within the next few weeks and i dont want her home alone or kenneled for the majority of the day. She deserves better than that. She is up to date on shots and goes to her annual well checks. Shes also been to doggy boarding and does great. Shes great with other dogs big or small and loves kids. she loves anyone that loves her honestly.She is not spayed but probably should be.She will come with all of her things to her new home.
