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 10:00am to 1:00pm at our rescue office (1721 W Harmony, unit 102, Fort Collins, Co 80526)! 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
Barkely is a 4 1/2 yr  Pittie/Mastiff/Heeler mix & a very handsome good boy.  He heartily eats his food and treats. He enjoys a variety of veggies, fruit, yogurt, canned food, bone broth as toppers or in a West Paw Topple cup, and a good bone to chew. He also likes a dab of peanut butter before bed.  He's a goober!! He is like a train when it's time to go outside to play. He thinks it's a race to get to his favorite ball. He lives for fetch!! Return? Well, he returns and drops the ball a few feet away. He's still slowly working on return and give/release.  He is good on harness/lead to walk. He is a big boy, & is strong.  He is a "Velcro" dog. He wants to be near his human & is willing to scale a fence to get to you. Therefore- Barkley requires a 6 ft or higher fence. He can not be left unattended outside until you're positive he can not/will not clear the fence. Barkley needs a stable home life. Love, attention, training, and play are highly encouraged, and another dog is highly encouraged to continue dog behavior/play/training. He is kennel-trained, & potty-trained.  Please schedule your meet & greet today! November 5, 2024, 1:55 pm

Story
Meet Stewie, a lovable 4-year-old Mastiff mix looking for his forever home! Weighing in at 100 pounds, Stewie is a gentle giant whose biggest desires are cuddles and food. His past has left him a little overzealous when it comes to treats, so homes with small children might not be the best fit for him. Stewie is incredibly loyal and sweet, always ready to protect and love his family. He gets along well with other dogs, but due to his size and energetic play style, smaller dogs might not be the best playmates for him. Unfortunately, Stewie is not suited for homes with cats. This big-hearted boy had a rough start in life, having been starved before coming to his current foster home. Despite this, he’s shown an unwavering capacity for love and loyalty. Stewie is waiting for a family that can give him the care, attention, and endless cuddles he deserves. Please consider giving Stewie a chance to be your loyal companion! If interested please go to our website and fill out an application. You can find our application under the adoptable dogs icon. Thank you for choosing Ozzie and Friends Rescue. We can’t wait to connect you with your new fur-ever friend.  https://www.ozzieandfriendsrescue.org/   Ozzie and Friends Rescue makes arrangements for all dogs adopted to be transported all across the Western United States, Canada and Midwest.   November 6, 2024, 2:40 pm

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##
