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.

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##

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.

Story
Say hello to Delta, a super playful and affectionate female puppy bursting with energy! She’s quick to warm up to new people, bonding almost instantly with her foster family and our male dog sitter. Delta’s outgoing and friendly personality shines through, and she gets along great with other dogs and pets, especially her medium-sized doggy pal. While she’s a bit nervous on a leash and needs some training, her potty training is already on point! Delta loves to play and cuddle, making her a true lap dog and love bug. She’s very close to her sister and would thrive in an active home with a medium to large dog to keep her company if not adopted together. Ready for a fun, loving companion? Come meet Delta on Saturday! ##2542872##

Story
Henry is an adult male Pit Bull, born on May 3, 2021, and weighing 40 pounds. With a big heart and a love for adventure, Henry is sure to capture the affection of those who take the time to understand his unique personality. Despite his strong and confident exterior, Henry requires patience and experience to fully appreciate his loving nature. Henry's journey to becoming a friendly and well-behaved companion hasn't been without its challenges. Due to a lack of socialization during his formative years, Henry sometimes struggles with social cues, which can lead to misunderstandings in social settings. Fortunately, with dedicated training and care, Henry has made significant progress and thrives under the guidance of an experienced owner. What to Expect When Adopting a Dog Like Henry Slow and Steady Introductions: Henry is a "three-date dog," meaning he takes a bit of time to warm up to new people. Multiple meet-and-greet sessions will help him feel more comfortable and secure. Patience and understanding are key to gaining his trust. Continued Training and Guidance: While Henry excels in obedience commands such as sit, down, place, and boundary control, he needs ongoing training to reinforce his social skills. A pinch collar is recommended once trust is established, helping him maintain focus and control during walks. Adventure-Loving Spirit: Henry loves adventure and is a great companion for pack walks, though he may initially feel uneasy. His ability to walk calmly past other dogs without reacting is a testament to his progress and potential. Understanding Boundaries: Henry is not allowed on furniture to prevent dominance issues. Instead, he enjoys using his designated place as his own cozy sofa. This routine helps reinforce boundaries and ensure a harmonious living environment. Gentle Handling: Henry is sensitive about being grabbed by his collar. Using treats to lure him is a more effective approach, as it prevents him from shutting down and maintains a positive attitude. Breed-Experienced Owner: Henry requires an owner with experience in handling Pit Bulls or similar breeds. Understanding his needs and providing a structured environment will help him continue to thrive and grow into a well-rounded companion. By welcoming Henry into your home, you're inviting a loyal and adventurous spirit into your life. His journey of growth and the bond you'll build together will be rewarding and fulfilling. If you're ready to offer Henry the understanding and guidance he needs, he might just be the perfect match for your family!
