Story
Sadie is a 4MO adorable Mutt.  Sadie and her 3 siblings were found abandoned on the side of the road in Texas.  We are guessing she will be about 35-45lbs when full grown. We don't know how many of them there were originally, but unfortunately it's safe to assume there were others that didn't make it.  Once they were rescued they were brought to a local vet to get the proper care and support they needed since they were emaciated and dehydrated.  Once sadie and her siblings were healthy and stable, they made their way to our rescue here in CO where we are hoping they find families of their very own.  Here is what Sadie's foster Momma has to say about her: "This little pup is a bit shy at first but with treats and a few good belly rubs she’ll become your best friend! Once she’s comfortable with you, she won’t leave your side! Sadie’s a quick learner and is very treat motivated. She’s already learned sit and is doing really well with potty training. She sleeps through the night in her crate. We highly recommend having a crate for her at her new home. While she’d love to sleep with you, she has a very positive tie to her crate and we can tell it’s a place of security for her. Sadie is incredibly sweet and does well with other dogs. We’re working on walking a leash but she's doing great so far! She is loving and snuggly and it's been so fun to watch her learn how great humans and life can be when she isn't trying to survive on the side of the road."

Story
Rumi is a 4MO, 18lb Shepherd/Collie (we are guessing?) mix.  He is most likely going to be about 35-45lbs when full grown.  Rumi and his 3 siblings were found abandoned on the side of the road in Texas.  We don't know how many of them there were originally, but unfortunately it's safe to assume there were others that didn't make it.  Once they were rescued they were brought to a local vet to get the proper care and support they needed since they were emaciated and dehydrated.  Once Rumi and his siblings were healthy and stable, they made their way to our rescue here in CO where we are hoping they find families of their very own. Rumi's foster Momma has nothing but great things to say about him and his sister.  They quickly learned the dog door and have been doing well with potty training.  Rumi is incredibly snuggly and loving.  He gets along great with the other dogs in the home (big and small) and does well with all the humans, including the fosters kid.  Rumi loves to play and romp around the yard with the other dogs.  He is a happy, happy pup with lots of fun puppy energy.  He would do great in a home with another dog to play with, or someone who wants an adventure buddy and sidekick.  He is always up for whatever!  Since Rumi and his siblings seem to be super smart, he will thrive with someone who enjoys training and the rewards that come along with that.   If you are interested in adopting Rumi or one of his siblings, please fill out our adoption application at brighterdaysdogrescue.com ##2863953##

Story
Meet Hassan Breed: Husky / Kelpie Mix Sex: Male DOB: July 17, 2022 Weight: 66 pounds Health: Healthy and vaccinated Hassan is a striking, intelligent boy with soulful eyes and a strong, resilient heart. He was abandoned and rescued from a very busy roadway, where he was dangerously close to being hit by cars. Thankfully, he was saved in time — and now he’s ready for the safe, loving forever home he deserves. Despite his difficult beginning, Hassan has remained loyal, playful, and full of life. Personality Hassan lives peacefully with other dogs and enjoys being around humans. He loves going out for walks, running, and exploring the world around him. Playtime is one of his favorite things — especially chasing a ball or carrying around plush toys. When he first meets new people, Hassan can be a little reserved or cautious. But once he gets to know you, his personality softens beautifully, and he becomes affectionate and loyal. He just needs a little time to feel secure. Hassan does not like sharing his food, so he would do best in a home where feeding routines are managed thoughtfully and respectfully. Breed Info: Husky / Kelpie Mix This is a smart, athletic mix that typically brings: High intelligence and problem-solving ability Strong loyalty to their people Active energy that thrives with exercise A desire for engagement and purpose Hassan will do best in a home that enjoys walks, outdoor time, and mental stimulation. Owner Responsibilities Hassan will thrive with: Daily exercise (walks, running, play sessions) Continued positive reinforcement training Clear structure and consistency Managed feeding routines due to food guarding Patience while he builds trust with new people He is not difficult — he simply needs leadership, routine, and love. &#226&#154&#160&#239&#184&#143 Things to Consider Before Adopting Before bringing Hassan home, please consider: Do you have time for daily exercise and enrichment? Is your home and lifestyle stable long-term? Are pets allowed where you live? Can you provide structure and manage feeding separately if needed? Adoption is a lifelong commitment, especially for an active breed mix Hassan deserves a home that won’t give up on him. Vet Care Although Hassan is healthy and vaccinated, adopters should schedule a visit with their own veterinarian as soon as possible after adoption to establish care and continue his wellness routine. The 3-3-3 Rule First 3 days: Hassan may be cautious and observant as he adjusts. First 3 weeks: He’ll begin to learn your routine and feel secure. First 3 months: Trust deepens, and his loving, loyal personality truly shines. Patience and consistency will help him flourish. Why Hassan Is Special Hassan survived being abandoned and left in danger — yet he still chooses trust. He is playful, intelligent, and deeply loyal once he bonds. He deserves stability, safety, and someone who will show him that he is finally home for good. If you’re ready for an active, devoted companion who will stand by you with loyalty and heart, Hassan is waiting for you 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
Meet Mr. Oreo Male Age: 7/23/2022 Weight: 42 pounds Breed: Australian Cattle / Catahoula Leopard mix  Neutered (Fixed): Yes Vaccines: Up to Date Microchipped Healthy & Adoption-Ready Personality, Breed Info & Expectations Mr. Oreo's life hasn't always been easy. At some point, the family he trusted was no longer able to care for him, and he found himself without the security of a home or the comfort of someone who loved him. Like so many wonderful dogs, he didn't understand why his world had suddenly changed. Yet through it all, Mr. Oreo never stopped believing that kindness still existed. When he arrived at our rescue, it didn't take long for everyone to fall in love with him. His tail wagged the moment someone spoke to him, and despite everything he had lost, he greeted each new day with hope instead of fear. Dogs like Mr. Oreo remind us that love can survive even the hardest chapters of life. Mr. Oreo is a loving, happy boy who simply enjoys being with people. He has a warm, affectionate personality and is happiest when he can be close to his family. Whether it's joining you for a morning walk, relaxing at your feet while you watch television, or greeting you at the door after work with a wagging tail, Mr. Oreo is the kind of dog who makes a house feel like a home. He has reached a wonderful stage in life where he is playful without being overly energetic. He enjoys getting outside for walks and adventures but is equally content spending quiet evenings cuddling with the people he loves. His calm, joyful personality makes him a wonderful companion for families, couples, or individuals looking for a loyal best friend. Mr. Oreo would thrive in a home prepared for: Daily walks and moderate exercise Plenty of love and companionship Positive reinforcement training Mental enrichment through toys and interactive activities Structure, consistency, and routine A lifelong commitment to his emotional and physical well-being Mr. Oreo has already experienced what it feels like to lose a home. Now he's hoping to find a family that will promise him something he's waited his whole life for—a forever home where he'll always be loved, always be safe, and never have to wonder if he's wanted again. Training, Adjustment & What to Expect Like many rescue dogs, Mr. Oreo may need a little time to adjust to a new home, routine, and environment. Even the happiest dogs benefit from patience as they learn where they belong. Mr. Oreo is eager to bond with his family and responds well to kindness, consistency, and positive reinforcement. Continuing his training and daily routine will help him settle in quickly and build confidence. Mr. Oreo will benefit from: Positive reinforcement training Daily walks and regular exercise Continued socialization Mental stimulation through toys and games Consistent routines and clear expectations Patience, encouragement, and love 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 patience and love, Mr. Oreo will quickly show you just how wonderful a rescue dog can be. Owner Responsibilities & Veterinary Care Owning a dog is a lifelong commitment that includes training, companionship, exercise, and routine veterinary care. Mr. Oreo will need: Routine veterinary care and annual wellness examinations Preventative flea, tick, heartworm, and parasite protection Proper nutrition to maintain a healthy weight Daily exercise and mental enrichment Continued positive reinforcement training A safe, stable indoor living environment Consistent veterinary care, daily exercise, and plenty of love will help Mr. Oreo continue living a healthy, happy life for many years to come. Mr. Oreo is an indoor family dog and is not to be chained or left outside.
