Story

***Brody is in a foster home, so he is not at the kennel. If you are interested in him, please fill out an application at K9stray.com and we will be in touch. Thank you.*** Brody and his deep loving eyes... He is estimated to be about 7 months old and weighs 34 pounds right now, but he is sure to get much bigger! Meet Brody, a sweet pup with a sensitive, special soul, hoping to find his forever family. He's just a baby with cutest giant paws, so he's going to be a big boy! He is affectionate and very connecting, but mostly only with women right now. Unfortunately, he is quite scared of men, we are working on this with him, but Brody is seeking a dedicated leader to rely on and guide him through his insecurities and help him build confidence. Brody has had a challenging start, struggling with a fear of men due to past trauma. He absolutely needs an experienced adopter who can commit time upfront to help him overcome these fears and navigate the world with confidence. He is very food motivated, so this is a great tool to use to build trust with him. This sweet boy has so much love to give and with him still finding his paws in the world, he's looking for a family where any children are at least 13 years old, who can offer him patience, love, and the time he needs to blossom. He would love it if you came to meet him, he can't wait for his family to find him. f you are interested in Brody and are at least 21 years old, please come to our kennel during business hours, make an appointment, or fill out an application at k9stray.com and an adoption counselor will be in touch. We look forward to helping you find your new best friend! *Please check your lease agreements for breed/weight restrictions prior to applying. We also do not do cat testing, so we do not know how a dog will do with cats. Not all dogs are available to go home on the same day you first meet.*

You can fill out an adoption application online on our official website.If interested in any of our animals for adoption, or to foster an animal, please fill out the respective application here to get the process started. Visit our FAQ webpage for commonly asked questions about our adoption/foster process. Meet the magnificent Miss Hetti. She is a playful, energy abundant Mastiff, and likely, boxer mix. She loves tummy rubs, fetch, and Benebone chew toys. Hetti thrives on multiple walks per day however can over heat quickly in higher temps. She is very strong and still learning manners with passing animals so an experienced handler and dog owner is a must. She loves greeting people but due to her size and still puppy behaviors, a house with kids over 12 is preferred. For Hetti to live her best life she should be a solo canine with a large fenced yard and an active owner willing to give her the exercise and attention she needs. Visit this organization's web site to see any additional information available about this pet.Last Day Dog Rescue now microchips all animals before adoption. Microchips are implanted between the animals shoulder blades and are a permanent form of identification. If the animal is ever lost and slips his/her collar/tags the microchip allows the finder to know who to contact if scanned for a microchip. Animals MUST still have a collar with tags on at all times. Per our contract, we take all our animals back if for any reason you can't keep your adopted animal. Please understand the statements about this animal are based upon the foster home's evaluation of the animal. The animal might behave differently (negatively or positively) in your home. While the animal might be good with the current foster’s dogs, cats, children, etc., it may not be with your animal(s) or children. The animal may be housebroken or litter trained in the home of the foster but may relapse in your home. The animal is represented to the public as it performs in the foster home and any statements made regarding the animal are conditional to that foster home setting. Please understand that statements made regarding this animal are simply overviews and are not guaranteed. The Petfinder.com system requires that we choose a predominant breed or breed mix for our animals. Visual breed identification in animals is unreliable so for most of the animals we are only guessing at predominant breed or breed mix. We get to know each animal as an individual and will do our best to describe each of our animals based on personality, not by breed label. Thank you for looking through our list of animals needing forever homes and choosing rescue first. We appreciate you stopping by. March 7, 2026, 8:41 am

Meet Goose!! Goose is eagerly awaiting life with his forever family! He is the sweetest little Mastiff/Boxer mix you’ll ever meet! He has an estimated birthdate of 1/9/24 and weighs in at a whopping 86 pounds of charm and delight… and he’s currently underweight This super strong boy is great with other dogs and absolutely LOVES people!! Kids are his absolute favorite!! Goose is current on his vaccines but, because he had not been taken care of properly he’s tested positive for heartworms and is being treated for heartworms on slow kill method by The Artemis Project. But don’t let that stop you because the rescue will continue to provide and fund the medications for the duration of his treatment even after he is adopted Bottom line - he is SO ready for a wonderful life with… YOU!!. Please give this beautiful boy a chance to win your heart and become your best friend forever! He is looking for his forever family… that very well may be you! Currently this sweet baby is with our rescue, The Artemis Project, in Arkansas. We DO, however, transport monthly to the metro Detroit area of MI. Because we’re able to transport, we ARE able to accept adoption applications directly from residents of MI. Why do we transport? Because animal overpopulation is severe in our region, and stray and unwanted dogs have very little chance of finding a home here. These babies are, however, at a high risk of being neglected, abused, abandoned, euthanized or even shot (it’s “the way things are done” for some people down here). YOU are truly one of the only safe and happy endings for the lucky ones we are able to rescue. Upon approval of your adoption application, we will then transport your new furbaby to you in the metro Detroit area for just a small travel expense fee of $50 in addition to the adoption fee. MICHIGAN RESIDENTS—>PLEASE CLICK THE LINK BELOW TO FILL OUT THE ADOPTION APPLICATION: https://new.shelterluv.com/form/other/TAP/2450-michigan-adoption Before we can change your new furbaby’s status from "adoptable" to "adoption pending," the $50 transport fee must be paid to secure the adoption. At that time, we will stop accepting applications. The entire adoption fee must be paid prior to the transport in order to ensure your new baby has a spot on the transport. Thank you SO MUCH for giving a homeless Arkansas pup a chance at a real life with a family of their very own!

Story

You can fill out an adoption application online on our official website.Meet Bubs Born on January 21, 2026, Bubs is an adorable mastiff mix puppy with a whole lot of growing (and cuddling) ahead of him. With his cute black mask and big, clumsy paws, he may have some Cane Corso or Bullmastiff in the mix—but right now, he’s all puppy energy and sweetness. Bubs is incredibly affectionate and loves being close to his people. He’s the kind of pup who will happily follow you around, flop over for belly rubs, and then bounce right back up for playtime. Curious and gentle, he’s still figuring out the world one sniff (and probably one chew) at a time. Like any young pup, he’s learning his manners and building confidence every day. With a little guidance and a lot of love, Bubs is going to grow into a wonderful, loyal companion. For now, he’s just a big baby with a soft heart and an even softer spot for cuddles.Visit this organization's web site to see any additional information available about this pet.May 27, 2026, 7:21 pm

Story

Meet Tassels: A Gentle Giant with a Heart of Gold Introducing Tassels, also lovingly called Mumma by her fosters, a majestic 1.5-year-old Mastiff/Mountain Cur mix whose journey to happiness is truly inspiring. Rescued from a life of uncertainty while extremely pregnant and terrified, Tassels has shown incredible resilience. She was elusive for over a year, only seen on a Ring camera in the Detroit neighborhood she roamed, until we finally secured her safety. Since then, she has blossomed in foster care, watching her babies find their forever homes. Now, it's her turn! Why Tassels is Special: Loving and Affectionate: Tassels expresses her love by placing her massive head in your lap or under your hand for scratches. Her affectionate nature makes her a wonderful companion. Well-Trained and Mannered: She knows basic commands, is potty trained, crate trained, and walks beautifully on a leash. Playful and Joyful: Despite her size, Tassels is playful and enjoys the simple pleasures of cuddling, playing with toys, and lounging in the grass on sunny days. Her zoomies are a sight to behold and bring laughter and joy to everyone around her. Curious and Easygoing: Over the months, Tassels has overcome her initial shyness and now approaches life with curiosity and ease. She’s come to enjoy her interactions with people and her foster sibling. Tassels’ Ideal Home: Tassels would thrive in a home without cats or small dogs. She can live with another dog, but a proper, slow introduction is necessary to ensure a harmonious relationship. Her ideal family will be one that can provide stability, plenty of space for her to stretch her legs, and lots of love. She responds wonderfully to food, affection, and praise, making her a delightful and grateful companion. Is Tassels the Missing Piece in Your Family? If you’re looking for a loyal, loving, and serene companion to add warmth and joy to your home, consider welcoming Tassels into your life. She promises to fill your days with affection and happiness. Ready to adopt Tassels? Apply today! Visit our website to fill out an adoption application and learn more about how you can bring Tassels home! Adoption is $275, which includes spay/neuter at our vet, vaccines, dewormer, microchip, and clean bill of health. Although we work to potty train all of our dogs, we cannot guarantee full house training before adoption. Regression is a normal part of transitioning to a new home and we want our adopters to be prepared for that! APPLY on our WEBSITE: rebeldogsdetroit.com/applytoadopt
