Story
Zeus, a 3-year-old big and handsome Mastiff mix. He a loving dog with a goofy personality. He is looking for a calm forever home. He's known for his affectionate nature, enjoying cuddles, belly rubs, and being close to humans, including children. Zeus is house and crate trained, though he's still adjusting to calm leash walking. After a challenging year of transitions, he's ready for a stable environment where he can thrive. The ideal home for Zeus would include an owner experienced with large breeds, potentially working from home, to provide the love and companionship he deserves. Currently fostered in Denver, Zeus is eager to meet his new family.

Story
Max, a 3-year-old English Mastiff, is the epitome of a gentle giant. This big softie loves nothing more than leaning in for a cuddle session, offering warmth and companionship. Though his past may have been rough – filled with abuse and neglect – Max's spirit is under repair. He's taking each day in stride, slowly learning to trust the kindness around him. But Max isn't alone in his journey! He came to the rescue with his daughter, Riley. They can be adopted separately, although they'd love to find a forever home together, if possible. Are you looking for a loving companion with a heart as big as his size? Max (and maybe Riley!) could be the perfect addition to your family. They are potty trained, crate trained, and will be fully vetted.

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. 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.
