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

Are you looking for a life-long love? I'm sure to make your heart skip a beat with these longing eyes! Hey there, I'm Valentino! I've had a rough start in life as my owners moved and decided to leave my brother and I behind. We don't let it bother us as we know we will find our forever homes soon. We look to be a mix of Mastiff/Lab but the shelter isn't sure. Will you paw-lease adopt me? 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 ##2287925##

Story

Meet Koda, the ultimate best friend. This gentle giant is loving, playful and strong. He's looking for an adopter who can keep him active and has lots of tiime to play! He has a great time chasing tennis balls (although he doesn't always bring them back), and he loves romping in the snow. He's a sucker for treats, but his favorite thing is affection. We recommend older kids in Koda's new home.January 26, 2025, 6:40 pm

Denver, CO

Size

(when grown) -

Details

Spayed or Neutered,

Story

Aella wants to be a lap dog. She could easily cover two laps, of course, but size isn't an issue to her. She just wants to be loved. Young and energetic, Aella is a good walker and enjoys being outside, but after a quick run around the play yard, she heads back to her person for what she really wants: affection. She likes hard toys and doesn't like being alone. Because of her size and energy level, we recommend older kids in her new home.January 26, 2025, 8:09 pm
