Story

Sade is a high energy German Shepherd, Boxer mix. She gets along with other dogs but needs to be supervised at first because she can be a bit annoying to other dogs with her play style. She gets along with cats, horses, donkeys, and smaller animals like chickens with supervision. She has not been to the vet in a year. She has some issues gaining weight which may be caused by eating a battery before we adopted her. We are rehoming her because we are not giving her the time she needs and deserves.

This love bug is Oreo. Oreo is 4 years old, 44 lbs, and a Boxer/Lab mix. 3.5 years ago was the best day of her life when she got adopted into a wonderful home. She became house-trained, crate trained, trustworthy free roam, and she was loved beyond measure. Unfortunately, Oreo’s family is moving abroad and she doesn’t get to go with them, landing her in great need once again. Oreo is good with kiddos, most other dogs, and enjoys playing with cats! She has through the month of November before she will be homeless once again. Don’t let this girl pass you by, she’s a family dog and she belongs in a home. Oreo is in foster in Colorado Springs, Colorado. *We require all adopters to come to Colorado to adopt. *We do not transport dogs. * You can apply for our wonderful dogs at https://www.milehighcanine.org/adopt/adoption-application/.

Story

LION – Male Boxer | 2 Years Old - DOB 11/25/2023 | 50 lbs | Healthy, Vaccinated & Neutered Introducing Lion, the sweetest big-hearted Boxer boy you’ll ever meet! At 2 years old, Lion has that perfect blend of Boxer goofiness and soulful loyalty. He’s playful, affectionate, expressive, and absolutely loves being near his humans. Lion is the type of dog who wiggles when he’s happy, leans in for cuddles, and charms everyone he meets with his warm, gentle nature. Breed Info: Boxers are known for their intelligence, athleticism, and famously silly personalities. They are deeply loyal, people-oriented, and incredibly loving companions. Boxers thrive on interaction, bonding, and being included in family life. Lion reflects the best of his breed — goofy, devoted, and full of heart. Owner Responsibilities: To help Lion thrive, he’ll need: Daily exercise (walks, play, and engagement) Structure, training, and positive reinforcement Plenty of affection and time with his family A safe, stable home where he won’t be left alone too long Give him routine, purpose, and love — and Lion will give you devotion for life. Things to Consider Before Adopting Lion: Are you ready for a medium-energy, highly social dog? Do you have the time and stability for daily exercise and bonding? Is your home and landlord dog-friendly? Are you prepared to commit to a dog for the next 10+ years? Are you ready for a dog who wants to be included as part of the family, always? Dogs are forever — not until convenient. Vet Care: Lion is healthy, vaccinated, and neutered. Please take him to your own vet shortly after adoption to set up ongoing care and ensure his continued well-being. The 3-3-3 Rule & Lifelong Commitment: First 3 days: He decompresses and starts to feel safe. First 3 weeks: Lion learns your routine, expectations, and begins trusting fully. First 3 months: He bonds deeply, understanding he is truly home at last. Adoption is forever — and Lion is ready to give his heart unconditionally. Why Lion Would Be a Great Addition: Lion is a loyal, affectionate, and joy-filled companion who will bring warmth and love into any home. His expressive Boxer charm, playful energy, and gentle nature make him the kind of dog who forms bonds that last a lifetime. He’ll make you laugh, comfort you on hard days, and love you with everything he has. He’s not just a dog — he’s family. &#226&#157&#164&#239&#184&#143 If you are interested in adopting this amazing dog, please follow the link https://www.ozzieandfriendsrescue.org/adoptions and fill out an application Thank you for choosing Ozzie and Friends Rescue.

Gonzo - Needs a Hero Foster or Adopter!

Boxer American Bulldog

Female 5 yrs 11 mos

Boulder, CO

Size

(when grown) -

Details

Story

Greetings and salutations, Colorado, it’s me, Gonzo! I like to fancy myself a courteous and honorable gent, and my mom always told me begging is bad manners, but the Underdogs assured me that begging for a hero to help save you is the exception to that rule. Allow me to properly introduce myself. My name is Gonzo and I’m a 2-3 year-old gentle giant Boxer/American Bulldog mix buddy and I'm crossing all my paws for a hero foster or adopter. My Underdogs foster folks can only surmise that I was once somebody’s well-loved guy before I ended up in the dog clink. I have impeccable bathroom manners, walk politely on leash and lounge quietly on my dog bed. I’ll never know why my previous peoples stopped loving me and why they left me to wander the cold winter streets alone. What I do know, though, is that I’ve never stopped loving the peoples, ALL the peoples. Because man alive, do I love them! I could sweetly lean into them for pets and cuddles all day long. And if they gave me proper permission, I’d also happily cover them in my signature Gonzo smooches. It’s also my sole mission in life to make them laugh with my hilarious antics and sweet demeanor. I'm a calm dude in the home, but I also love to go for runs, walks and hikes. Basically, I'm down for all the Colorado adventuring. I do well around other good fit dog friends, but my best fit home may be one where I'm your only four-legged best bud. Believe me, I've got so much love to give, one Gonzo guy is all you'll ever need. I truly am such an easy well-mannered giant lover, I just know you'll love me once you meet me. I'm neutered, vaccinated If you’re interested in learning more about me and hopefully set up a meeting, please fill out an adoption application at https://underdogsrescue.org/adopt-form/ and if you're interested in helping spring me from this sad and lonely dog clink by helping to foster me, I would be soo sooo grateful, please fill out a foster application at https://underdogsrescue.org/foster-form/ . ##1906137##

Hi, I am Hoss. I am a super sweet, gentle and loving pup looking for a home. I like to cuddle, chew on bones and play with my best friend. I can be jumpy when excited and pushy when excited so I would like to meet any other dogs in the home before adoption. I did come to the shelter with my best friend Grace and we would love to go home together. We would love to meet you and become a part of your family.

Story

Posie is a beautiful, intelligent dog who’s been working hard on her training for several months and has made great strides with the help of a dedicated trainer. She is looking for a very specific kind of home—one where her boundaries are respected, her training is maintained, and her environment is predictable and safe.Posie is not a dog-park kind of girl. She can be resource aggressive with both dogs and humans, especially around food, toys, and even people she bonds with. She requires strict management and supervision around other animals and should never be left alone with other pets. For this reason, she will thrive best as the only dog in the home.While Posie has slowly learned to tolerate and even bond with her trainer’s dogs, that process took over a month and still requires careful attention to avoid conflicts. Her ideal adopter will be someone committed to continuing her structured training using tools like a remote collar and positive reinforcement, especially in public or off-leash environments. When her training is followed, she does beautifully on leash and can pass other people and animals calmly and confidently.Because Posie can be reactive with humans over resources as well, she needs an adult-only home with dog-savvy adopters who understand how to read canine behavior and are comfortable managing a dog with strong opinions and boundaries.Posie is not the dog for every home—but for the right person, she will be an incredibly loyal, loving, and rewarding companion. If you're experienced, patient, and ready to continue her training and give her the structure she needs, Posie will return your dedication with endless heart.We are committed to finding the perfect match for Posie to set her—and her future family—up for success. If you're interested, we’d love to talk and set up a time for you to meet her with guidance from her trainer. Check me out https://www.instagram.com/reel/DIZRDwAxIy0/?igsh=cHN5YzVtNnNlbTB3 I'm around 6 years old and 40lbs and have been waiting for my forever home for 560+ days. ##1953751##
