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
Mira is a 4MO Collie/Shepherd (maybe?) mix weighing about 12lbs.  We are guessing she will be about 35-45lbs when full grown. Mira and her three 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 Mira 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.   Mira's foster says she is a sweet, happy, smart pup.  She gets along well with other dogs, big and small, and all humans.  She love to romp around like all pups, but loves to snuggle just as much.  She is smart and training is going well.  She is going to be perfect for someone who is looking for a best friend/side kick for every activity from lazy cuddle days, so adventure days to see everything Colorado has to offer.  She is just a great little girl and will truly fit in with any family.

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.
