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

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

Thor may be the biggest puppy in the bunch, but he's also one of the biggest goofballs. Still growing into those oversized paws, Thor has a habit of tripping over his own feet as he bounces through life looking for his next playmate. He's the self-appointed director of fun, always encouraging everyone around him to join in. If another dog isn't interested in wrestling, Thor has no problem recruiting one of his brothers instead! Even with his playful personality, Thor enjoys taking life at a slower pace. When playtime winds down, he transforms into an affectionate cuddle bug who happily stretches out across your chest and gently nibbles your ear while soaking up attention. Thor loves wrestling with his brothers, carrying around stuffed animals, and being wherever his people are. He's a bold, loving puppy with a silly personality that's guaranteed to keep you smiling.

Story

Don't let Moose's serious, sleepy expression fool you—this big puppy is a total sweetheart with a soft spot for snuggles. While he enjoys wrestling with his brothers and a good game of tug-of-war, Moose is one of the more laid-back pups in the litter. He's happy to explore the world at his own pace, stopping often to sniff every interesting thing along the way. His favorite place, though, is in someone's arms with his head resting on their chest, soaking up all the love he can get. Moose loves batting around a ball, playing with stuffed toys, and spending time with his siblings, but he always makes time for cuddles. As he grows into the large dog he's destined to be, there's no doubt he'll become the kind of companion who thinks he's still lap-sized and wants to be as close to his people as possible. If you're looking for a gentle, affectionate puppy with the perfect mix of playfulness and cuddle time, Moose is ready to steal your heart. This pup will be available to meet starting on 1/29 They were rescued from a shelter in New Mexico. Meet and greets are by appointment only. An approved application is required to schedule a meeting.

Story

Adoption Fee: $475 When available, all animals are fixed in accordance with Colorado law, up to date on vaccines (may need boosters), and microchipped! What we know: Mother-daughter duo transferred from Española Humane Society in New Mexico after being rescued from another overcrowded shelter within the state. The mother is 4 years old, and her daughter is 2 years old. From the foster: This gentle giant is a Saint Bernard is with the sweetest disposition you could ask for. Missie is happiest when she's lounging — whether that's stretched out on the cool tile floor beating the heat, or curled up on the couch relaxing with her foster pack. She's got that classic laid-back Saint Bernard charm and isn't in a rush to do much besides enjoy the good life. Missie is house trained and walks beautifully on a leash, making her an easy addition to daily routines. She's curious and warms up to new people at her own pace, and she's a total sweetheart with other dogs — friendly with everyone in the pack. She's currently working on her manners, learning commands like sit and lay down, and could use an adopter willing to keep up with some positive reinforcement training. She's also building her confidence with car rides and navigating stairs, so a patient, encouraging home will help her thrive. If you're looking for a mellow, affectionate companion who just wants to be near her people (preferably on the comfiest cushion in the house), Missie could be your perfect match! www.coloradopuppy.org/how-to-adopt
