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.

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
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##
