Story
Little Johnny is a 10lb unique, adorable mutt.  We are guessing he is Dachshund/Chihuahua/Cattle Dog/Boston Terrier/Pug mix?  He has an adorably long body with short little legs and a squished little face.  We hope his forever family does a breed test on him because he is so cool! Johnny was dumped in a parking lot in Texas.  He was so confused and terrified the first week, that the person who found him said he wouldn't eat and was completely shut down.  We can't imagine what was going through his little mind.  He made his way to CO to prevent him from ending up in a shelter.  He has settled in here and is doing very well in his foster home.  Johnny's foster has fostered almost 100 dogs for us, and said he is the sweetest, most loving, and affectionate dog she has ever had.  Just like when he was dumped, he was terrified at first, but attached to his foster Momma pretty quickly.  He is definately a dog who bonds quickly and needs someone who can reciprocate the immense amount of unconditional love he has to give.  He gets along great with other dogs but doesn't seem interested in playing with them, yet(?).  He gets along amazingly well with cats and loves cats.  He would do great in a home with another cat as his best friend.  He also loves to play with cats.  Johnny gets along well with kiddos but since he is a nervous little guy we think older kiddos would make him most comfortable.  Johnny is just truly an amazing, affectionate, loving little guy, just looking for stability and security. If you are interested in adopting Johnny, please fill out our adoption application at brighterdaysdogrescue.com ##2822521##

Story
  Sometimes, when a person dies, there are little lives left behind who don't understand where their person went—or why everything they knew has suddenly disappeared. Meet Jessie a sweet Boston Terrier who, along with Allie, lost her beloved owner in December. For months, their neighbors rallied around them, taking turns feeding and caring for the girls and doing everything they could to keep them safe. They were their little community's responsibility, and everyone pitched in because no one wanted these two senior girls to go to the shelter. But recently, the house sold. Jessie and Allie had to leave the only home they knew. Thankfully, a kind foster stepped up and gave them a safe place to land. But it's only temporary, and these two little souls desperately need a permanent home. Jessie is 14 years old and weighs just 14 pounds. She is a tiny little lady with a big heart. She takes Novox and Tramadol for neck pain, but otherwise she's a sweet, easy companion. She is spayed and current on vaccinations. Neither girl is particularly fond of cats, so a feline-free home would be best. They are not bonded and in their foster home are not bothered when they are separated so they do not need to be adopted together. If you would like to adopt, please complete an application at:  https://www.circle2rescue.com/dog-adoption-application/  Adoption Fee: $50  Includes spay/neuter, age-appropriate vaccinations, deworming, and a microchip. ##2820694##

Story
My adoption fee is 75% off thanks to a grant from the Petfinder Foundation. So, it would only be $50 to make me a part of your family and give me a new chance at a joyful life! Hi, I'm Romeo! I was brought here as a tiny puppy from a place where I was barely getting fed. I was adopted shortly after and recently got returned due to weird circumstances. I suddenly had two injuries- one was my eye which needs to be removed and the other is much more. I have a torn cruciate ligament. The shelter is currently raising money to pay for my surgery but I will need a place to stay for 6-8 weeks with cage rest so I can recover. I'm a sweet boy and get along with everyone, even livestock!  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 ##2352756##

Meet Faith, a sweet and gentle young Boston Terrier with a heart of gold. Though she is possibly deaf and a bit shy at first, her affectionate nature shines through once she feels safe. She is looking for a quiet, patient home where she can decompress and bond deeply with her new family. Faith would make the perfect, loyal lap dog for a calm household. She is very submissive and seems interested in other dogs. She is curious about new surroundings and has a very quiet demeanor. An ideal home would be a calm, patient environment.❤️🐾

Karma is a beautiful little Boston Terrier/Frenchie mixes (with perhaps some Chihuahua?), approximately 6 years old and around 15 lbs. Karma likes playing, running and being silly with everyone she meets. She was surrendered to us, because sadly, her person becoming so sick, they could no longer care for her properly. She is well adjusted to home life, and was a definitely well loved dog! She very seldomly barks and is so sweet and loves to please. Karma gets on her hind legs to beg for treats or pets. She doesn't mind cats, and love kids, too! Cuddling on the couch is a must, and playtime and tricks for treats are fun for them as well. Come meet this delightful little dog! You will be thrilled you did!

These pups are in Boulder, Colorado too!

Story
Meet Ray Ray A Fresh Start for a Loving Frenchie Ready to Find His Forever Family ❤️ Breed: French Bulldog Gender: Male | DOB: August 5, 2023 (3 Years Old) | Weight/Size: 20 lbs (Small) Good With: Dogs ✔️ | Cats: Unknown | Kids ✔️ Medical: ✔️ Neutered | ✔️ Vaccinations Up to Date | ✔️ Microchipped Location: Los Angeles, California Transportation: Ozzie and Friends Rescue provides safe transportation to approved adopters throughout the United States. ❤️ Personality, Breed Information & Ray Ray's Story Ray Ray's journey brought him to rescue after his previous family made the difficult decision to surrender him. While saying goodbye was undoubtedly a major change in his life, Ray Ray hasn't let it diminish his loving personality. He's embraced his second chance with a wagging tail and is now searching for a forever family that will love him for the rest of his life. Ray Ray is an affectionate, playful little guy who absolutely loves attention. If you're looking for a dog who enjoys being close to his people, Ray Ray is your perfect match. He happily greets everyone he meets, loves being petted, and never turns down an opportunity for belly rubs or cuddles. His cheerful personality and goofy expressions have a way of making everyone around him smile. Whether he's playing with his favorite toy, following you from room to room, going for a leisurely walk, or curling up beside you after a fun day, Ray Ray simply wants to be included in family life. He's happiest when he's surrounded by the people he loves and thrives on companionship. As a French Bulldog, Ray Ray has all the wonderful qualities that have made the breed one of the most popular family companions. French Bulldogs are affectionate, loyal, adaptable, and known for their fun-loving personalities. They are intelligent dogs who enjoy spending time with their families and don't require excessive exercise, making them wonderful companions for many different lifestyles. Ray Ray would thrive in a home that offers: Plenty of love and companionship Daily walks and moderate exercise Positive reinforcement training Interactive toys and enrichment A consistent daily routine A comfortable indoor home where he's treated as part of the family A lifetime of love, patience, and commitment Ray Ray has already experienced one major life transition. Now he's looking for the family that will give him the stability, affection, and forever home he's been waiting for. Training, Adjustment & What to Expect Although Ray Ray has previously lived in a home, every rescue dog needs time to adjust to a new environment. New routines, unfamiliar surroundings, and different people can take a little time to understand. Please remember the 3-3-3 Rule: 3 Days to decompress and begin feeling safe 3 Weeks to learn your household routine 3 Months to fully settle into family life Ray Ray is eager to bond with his new family and responds well to patience, consistency, and positive reinforcement. His new family should continue providing: Positive reinforcement training Daily walks and interactive play Consistent routines and gentle guidance Continued socialization Plenty of love, reassurance, and encouragement With a little time to settle in, Ray Ray will become a devoted companion who loves nothing more than sharing everyday life with his family. Owner Responsibilities & Veterinary Care Adopting Ray Ray is a lifelong commitment that includes providing excellent veterinary care, companionship, and a safe, loving home. As part of responsible pet ownership, Ray Ray will need: Annual veterinary wellness examinations Routine vaccinations as recommended by your veterinarian Monthly flea, tick, and heartworm prevention A balanced diet to maintain a healthy weight Daily moderate exercise and mental enrichment Continued training and socialization A safe indoor home where he is treated as a cherished member of the family Because French Bulldogs are a brachycephalic (short-nosed) breed, Ray Ray should avoid excessive heat and strenuous exercise during warm weather. Access to shade, fresh water, and climate-controlled environments will help keep him comfortable and healthy. Adoption Information If you are interested in adopting Ray Ray, please complete an adoption application by visiting: https://www.ozzieandfriendsrescue.org/adoptions Thank you for considering adoption through Ozzie and Friends Rescue, a Los Angeles-based nonprofit dedicated to giving dogs a second chance at a loving home.

Ray Ray may have lost one home, but he hasn't lost his ability to love. He's ready to fill his forever home with laughter, companionship, and endless affection—and he can't wait to meet the family who will love him forever. ❤️August 25, 2026, 5:43 pm

Story
Meet Diamond Female DOB: 7/22/2024 Weight: 18 lbs Spayed (Fixed): Yes Vaccines: Up to Date Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Diamond's life almost ended before it truly began. She was discovered abandoned on the side of a rural road, frightened, hungry, and waiting for someone who never came back. She stayed in the same area for days, hoping her family would return, surviving on scraps and the kindness of strangers passing by. When our rescue was finally able to bring her to safety, Diamond was underweight, exhausted, and understandably confused. Although her heart had been broken, she never stopped believing that people could still be kind. Today, Diamond is a completely different dog. She has blossomed into a happy, spunky little girl whose playful personality shines brighter every day. She loves making people smile with her silly antics, enjoys chasing toys around the house, and has an infectious enthusiasm that reminds everyone how resilient dogs truly are. Her favorite place is wherever her people are, whether that's joining you for a walk, relaxing on the couch, or simply following you from room to room with her adorable little Pug waddle. Diamond is affectionate, loyal, and thrives on human companionship. She has a loving personality, playful nature, and desire to be involved in every part of family life. She is happiest when treated as true members of the family and enjoy a wonderful balance of playtime, cuddles, and quiet evenings with the people she loves. Diamond would thrive in a home prepared for: Plenty of love and daily companionship Moderate exercise and leisurely walks Positive reinforcement training Interactive toys and fun play sessions A comfortable indoor lifestyle Structure, consistency, and routine A lifelong commitment to her emotional and physical well-being Diamond has already experienced what it feels like to be left behind. Now she's searching for the one thing every dog deserves—a family that will love her unconditionally and promise that she'll never be alone again. Training, Adjustment & What to Expect Diamond has adapted beautifully since entering rescue, but like many dogs with difficult pasts, she may need a little time to fully settle into a new home. Patience, consistency, and kindness will help her realize that she is finally safe. She is intelligent, eager to please, and responds well to gentle, positive reinforcement. As her confidence continues to grow, her playful personality becomes more apparent each day. Diamond will benefit from: Positive reinforcement training A consistent daily routine Moderate daily walks and playtime Gentle socialization with new people and places Mental enrichment through toys and interactive games Patience, encouragement, and lots of affection Please remember the 3-3-3 Rule: 3 days to decompress 3 weeks to learn your routine 3 months to fully feel at home With love and patience, Diamond will continue to shine and become an incredibly loyal and devoted companion. Owner Responsibilities & Veterinary Care Owning a Pug is a lifelong commitment that includes routine veterinary care, companionship, exercise, and attention to the breed's unique needs. Diamond will need: Routine veterinary care and annual wellness exams Preventative flea, tick, heartworm, and parasite protection Proper nutrition to maintain a healthy weight Moderate daily exercise while avoiding overheating Plenty of companionship and mental enrichment A safe, stable indoor living environment As a brachycephalic (short-nosed) breed, Diamond should avoid strenuous exercise during hot weather and should always have access to fresh water, shade, and air conditioning when temperatures rise. Diamond is an indoor family dog and is not to be chained or left outside. Adoption Information If you are interested in adopting this wonderful dog, please complete an adoption application by visiting: https://www.ozzieandfriendsrescue.org/adoptions Thank you for considering adoption through Ozzie and Friends Rescue, a Los Angeles-based rescue dedicated to giving dogs a second chance at a loving home.

Story
Jack is a 3-4 year old Pug weighing about 16lbs.  Jack came from Mexico where he was brought to a shelter in pretty bad condition.  His eye was damaged and needed to be removed immediately.  We don't know what happened to his eye, but he has since fully recovered and is happy, healthy little guy!   Jack gets along well with all people and is an amazing little guy.  He is very snuggly and loves to follow his foster Momma around the house.  He gets along with other dogs but since he is a sassy little Pug a proper introduction is usually necessary.  He does well at the dog park and LOVES chasing his tennis balls and playing fetch. He is great on walks and a cute little snorty, happy Pug. If you are interested in adopting Jack, please fill out our adoption application at brighterdaysdogrescue.com ##2668187##
