Story
Uma is an approximately 9-year-old Mastiff mix with the gentlest heart. She is a giant cuddle bug who believes she is a lap dog and loves nothing more than being close to her people. Uma is sweet, calm, and incredibly affectionate.Uma was adopted as a rescue, and her early life was difficult. Because of past trauma, she can become reactive on walks, but with a proper harness and mindful handling she does very well.She has lived peacefully with dogs, cats, and children of all ages, including babies, whom she absolutely adores. Slow introductions to new animals may help her feel safe, but she has never harmed any people or animals.Mastiffs have relatively short lifespans, and our greatest hope is to find Uma a loving home where she can spend her senior years surrounded by comfort, affection, and family.Uma is currently in Centennial, CO and is ready to meet you!

Story
This pups adoption fee has been partially sponsored by All Aboard or an All Aboard partner! The new adoption fee is reflected on the profile. IMPORTANT NOTE REGARDING THIS DOG: Ombre can be easily startled by new people and things. He is occasionally slower to meeting new people, especially men, and other dogs. Ombre has the potential to get overwhelmed easily and can resource guard. Ombre needs an adopter who is patient and willing to continue his training. Ombre is big guy with a lot of love to give! He came to us with a few quirks that his foster has been helping him work through and he is constantly making progress! He does need an experienced adopter who will be dedicated to continued positive reinforcement training and ongoing socialization. He has come a long way since his arrival in January 2023 and needs the perfect partner in crime to help him continue making progress! Ombre can be a bit skittish with new sounds or unexpected movements and can resource guard at times. He is occasionally slow to warm up to new men and other dogs, but not consistently! He can get overwhelmed in new high-activity environments, so continued socialization is a must. Ombre is very loving and curious, and acts like he is his foster's shadow. This loving boy is a classic case of a dog who is worth the effort! With the right, experienced adopter who is committed to setting him up for success through continued training and socialization, Ombre will absolutely blossom into his adopter's most dedicated friend! He is house and kennel trained. Playgroup - https://youtube.com/shorts/Brmr_wwiRKs ADOPTION FEE: $75 We are a foster-based rescue and do not generally have pups available to meet at our office except during adoption events on Saturdays. Interested in this pup? The first step is to complete our online application by clicking the "Apply for Adoption" button. Please note that we are only able to finalize adoptions at events for approved adopters. The earlier you apply, the better as it takes time to review and approve applications. We host adoption events almost every Saturday from 11:00am to 2:00pm at Petco in Fort Collins (2211 S College Ave. STE 200, Fort Collins, CO 80525)! Check our Instagram and/or Facebook page for info on where we will be hosting adoptions this weekend! All Aboard Animal Rescue saves dogs and puppies from high-kill shelters in other states. These pups are brought to Colorado, where they are required to be spayed or neutered - breaking the cycle of unwanted litters of puppies who end up as strays! Please consider supporting us in this mission by adopting, fostering, volunteering, or donating.

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.

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##

Lucy, St Bernard, 6.5 months. Lucy is well mannered. She gets along well with other animals, dogs and cats. She’s got lots of energy to play. She likes running around in circles in the yard. She’s housetrained and updated on her vaccinations. Her family adopted her as a puppy with three kids and two adults in the home. She had a cat that she loved. We want a home with someone home most of the time or another young dog for her to play with. But the family cannot keep her as they have to relocate to an apartment. Courtesy listing.
