Meet Sprout Sprout is a small, 28-pound Shepherd mix who may be young, but she has plenty of personality packed into her petite frame! At around a year old, Sprout is playful, energetic, and ready for a home where she can get the exercise, attention, and fun she’s been missing. She’s dog friendly and loves getting to romp and play with her canine friends. Sprout is the kind of girl who is ready to leave the shelter behind and start learning what it’s like to be someone’s beloved dog. With her small size, youthful energy, and sweet face, she’s an easy one to root for. If you’re looking for a compact Shepherd mix with plenty of life and love to give, Sprout could be your girl! ##2860959##

Story
@Ireland Tawney  WILLIE NEEDS A FOSTER HOME Somehow, two years later, we’re getting to introduce this handsome boy to you all over again. The puppy in the first photo? That’s Willie. And the handsome 2-year-old boy in the second photo? Also Willie. Willie was adopted from LOLAs Rescue as a puppy, and now he has found his way back to us and needs a foster home. Willie is a 58-lb Border Collie/Pit mix who is wicked smart, affectionate, friendly, and eager to please. He loves to learn, enjoys running and playing, and is happiest when he’s with his people. He is: 2 years old 58 lbs Neutered Housebroken Crate trained Moderate energy Great with the children he has been around Has lived with cats and done well with them Willie would love to be your one-and-only pup. Willie’s relationship with other dogs can be a little complicated. The majority of the time, he has played and interacted well with other dogs in home, daycare, and boarding environments, but he has also had some unpredictable moments with other dogs. Because of that, we feel he will be happiest and safest in a home where he doesn’t have to share his space with another dog. A dog-free foster home will give Willie the opportunity to settle in, relax, and thrive while we continue learning more about him. What Willie needs in a foster:• A home without other dogs• A secure environment• Structure and consistency• Someone who enjoys an active, intelligent dog• A little patience while he settles in Willie has a lot of love to give and is ready for his next chapter. If you can open your home to Willie, please apply to foster with LOLAs Rescue and send us a message once your application is submitted. And please share this post. Willie has already been loved once by LOLAs — now we need to help him find where he belongs next. Apply online at www.lolasrecue.com ##2015191##

Angle is a 4.5 Year Old Great Dane/Smooth Coated Collie Mix. She loves playing with other dogs and ignores cats, unless they want to play. She loves her people and even though she loves playing with other dogs, she really wants her human all to herself. She is also laid back and enjoys a good cuddle and chill on the couch while catching up on some TV. Angle is crate trained, enjoys toys and completely untrustworthy on free roam with high interest items (this includes expensive items; we don’t know how she knows – but she does!) If you think you are Angle's forever home, please complete an adoption application at https://www.savethegiants.com/adoption-process .

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
Meet Jasper — This good looking Border Collie pup is around 7 months of age and weighs 47 pounds.   Handsome? Absolutely.Sweet? Without a doubt.Affectionate? Oh, you bet! Jasper is a striking black-and-white Border Collie with expressive eyes, a gorgeous coat and a personality that is impossible not to love. At just 7 months old, he's already proving that being a Border Collie isn't just about brains and beauty — it's also about having a BIG heart. Jasper loves spending his days playing with other dogs, so a playful canine companion would be a wonderful bonus in his new home. He's got the fun, bouncy energy you'd expect from a young Border Collie and would thrive with a family ready to give him plenty of playtime, exercise, attention and opportunities to keep his clever little brain busy. But Jasper's favorite activity might just be loving his people. This boy is an absolute hugger. And we're not talking about a little lean against your leg. Jasper will actually wrap himself around your legs for a full-on hug! Jasper is also doing great with his kennel manners. He keeps his kennel clean, although if Jasper were writing the rules, we're pretty sure “spend time in the kennel” would be struck from the handbook immediately. He'd much rather be out playing with his dog friends or hanging out with his people. Jasper's Ideal Home Jasper would love a family who: Wants an affectionate, people-loving companion Enjoys having a playful dog around Can provide plenty of exercise, play and mental stimulation Will continue his training as he grows Doesn't mind a dog who believes every human leg is an invitation for a hug Jasper is young, energetic and still has plenty of puppy growing to do, but underneath all that playful energy is a wonderfully affectionate, social and loving dog. He's handsome. He's playful. He's smart.  Interested in adopting?

Story
Meet Nona Some dogs don't need much time to show you what they're made of. Nona is one of those dogs. This beautiful reddish-brown Australian Cattle Dog mix is about 2 years old, weighs a petite 30 - 35 pounds, and has the sweetest combination of intelligence, affection and attentiveness. But what really sets Nona apart is how easy and loving she is. Nona can be a little timid when meeting someone new, but give her a little attention, encouragement and praise, and she warms up quickly. She is affectionate, eager to please and happiest when she's getting a little love and making you proud. Nona is also wonderfully easy to live with. She loves going for walks and is a great little walking companion. She doesn't bark at people passing by, is curious about her surroundings and enjoys meeting other dogs without feeling the need to greet every single one. She's perfectly happy to mind her own business and enjoy the outing with her person. She is comfortable living with other dogs and currently shares her foster home with a middle-aged male Lab, but Nona doesn't need another dog to be happy.  It's been wonderful watching Nona discover what it's like to be loved and cared for. She came from a life where she was living outdoors on her own, and she's learning that life can be very different. A soft bed, a loving family, a warm home and someone who thinks she's pretty special? Turns out Nona is a big fan of all of it. At home, Nona is house trained, walks beautifully on leash and is wonderfully well behaved. In fact, when her foster mom is away, Nona's favorite place to nap is right on the bed. And yes, she's absolutely earned those bed privileges! If you're looking for a loving, loyal and easygoing companion who will happily walk beside you, curl up next to you and make you feel like her favorite person in the world, Nona would love to meet you. A Note About Nona's Heartworm Treatment  Nona has tested heartworm positive, but this is absolutely treatable, and Circle 2 Rescue will cover the cost of her heartworm treatment. Her treatment will involve approximately three veterinary appointments, currently planned for November 22, December 22 and December 23 (dates may be adjusted slightly if need be). Her adopter will not be responsible for the cost of this treatment. We simply want Nona to have a wonderful home to recover in while she completes her treatment and gets ready for her heartworm-free future. Interested in adopting Nona? Please complete an adoption application at Circle 2 Rescue Dog Adoption Application  Adoption Fee: $250, which includes: Spay  Age-appropriate vaccinations  Deworming  Microchip ##2819823##
