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
0926037 -  Meet Brookie! Brookie is an adorable 1-year-old Heeler mix with a gentle, loving personality. She can be a little shy at first, but once she feels comfortable, she’ll become your little shadow—following you from room to room and happily snuggling up with you on the couch or in bed. At night, she’s perfectly content sleeping in her own dog bed on the floor… because apparently humans aren’t willing to give up all the bed space. Brookie is house trained and kennel trained, although she may serenade you with a little howling if she can hear you nearby while she’s kenneled. Because of this, a house may be a better fit for her than an apartment. She gets along well with other dogs, enjoys playing fetch, and absolutely loves her stuffie toys. She’s also met a few cats, and so far her response has basically been, “Nope, you’re scary,” before politely walking away. Brookie has a sensitive, sweet nature and would probably be happiest in a more mellow household where she can settle in, build her confidence, and have plenty of love and snuggle time. If you’re looking for a loyal little companion who wants nothing more than to be by your side, Brookie might be your girl!

&#226&#156&#168 Meet Erica — Your Ride-or-Die Adventure Girl! &#226&#156&#168 If you’re looking for a best friend, shadow, and lifelong sidekick, Erica is that girl. Erica is a 4.5-5 Month old with a big personality and an even bigger heart. She’s loyal, smart, and spunky, the kind of dog who wants to be wherever you are — hiking trails, weekend adventures, or just following you from room to room like your built-in bestie.  Erica in a nutshell: A true ride-or-die companion Smart, eager, and excellent adventure material Great with dogs and people Best with older kids or kids who understand big-dog energy Already crate trained & dog-door trained (yes, already!) Would love a canine buddy to pal around with Important to know: Erica is not an apartment dog — she’s a bit of a talker when left alone and prefers a home where she has space, stimulation, and ideally another dog for company.March 9, 2026, 5:54 pm

Story
Adoption Fee: $475 When available, all animals are fixed in accordance with Colorado law, up to date on vaccines (may need boosters), and microchipped! What we know: Litter of 6 transferred from Animal Services Center of the Mesilla Valley in NM. Found on the side of road when finder was on his way to work, he drove the road looking for mom but could not find her and brought the puppies to the shelter to receive proper care. ***I have been diagnosed with Megaesophagus. Megaesophagus is a common condition that decreases mobility in the muscles of the esophagus, the tube that connects the mouth and stomach. This decreased muscle function leads to esophageal dilation, or enlargement. This seems to be a defect from birth and no surgery is needed and there is no actual treatment that can fix this condition. This is a life long condition, that will require proper management during feeding time to prevent recurrent pneumonia and regurgitation like using a Bailey chair, upright feeding, as well as a daily prescription (Sildenafil) to help decrease lower esophageal sphincter pressure to facilitate passage of food into the stomach; dosing would need to be adjusted with growth and weight gain. Overall puppies seem to be happy and active.*** From the foster: It has been an absolute joy to foster Cheeto for almost two months, and we can honestly say she is just the sweetest pup. Cheeto loves to be with her person. If you sit down, she’ll happily ask to climb into your lap, lick your face, and eventually settle in with her head resting on your chest. She is incredibly affectionate and has all the makings of a truly wonderful companion. She’s also growing some impressively long legs and is very curious about everything happening up high — on the counter, in a chair, on the couch… apparently the best things in life require a better view! We’ve been working on her “counter surfing,” and she’s making great progress. She definitely has some natural agility! Cheeto is playful, silly, and LOVES her toys — especially anything she can chew, pull apart, and proudly de-fluff. Because of her medical condition, traditional long-lasting chews like bully sticks and yak chews aren't a good fit for her, as they can trigger reflux and regurgitation. Thankfully, Cheeto couldn't care less as long as she has a basket full of toys to chew, destroy, and investigate. Give this girl a stuffed toy and she is perfectly happy! Cheeto has also been hard at work on potty training and has made huge progress with going outside. We use tiny crumbs of liver treats as rewards, which have worked well for her, and she is very eager to please. Keeping up a consistent routine — especially taking her outside after naps and meals — will help her continue to succeed. She also has possibly the cutest, deepest puppy pee squat we’ve ever seen. Feeding & Medical Care After lots of trial and error, we have found a feeding routine that is working wonderfully for Cheeto. Traditional kibble irritates her esophagus and causes much more frequent regurgitation, but she has done incredibly well on The Honest Kitchen dehydrated puppy food. We simply add warm water, and the difference has been amazing. Her regurgitation has significantly decreased, she has gained great weight, her coat is incredibly soft, and — most importantly to Cheeto — she LOVES mealtime. Cheeto does need to eat upright and remain upright for approximately 2–5 minutes afterward to help her food make its way down. She also takes medication twice a day — just half a pill with each meal. We place it right on top of her food, and she eats it without a second thought. Right now, we hold her upright in our laps with her bowl elevated and slightly angled. But Cheeto is getting a very special upgrade: her own Bailey chair! We’ll be helping her learn to use it before adoption, and her chair will go with her to her forever home so her new family already has an important part of her routine ready to go. And truly, once you learn Cheeto’s routine, the medical care is only one small part of who she is. She is the puppy who wants to curl up against your chest. The puppy who happily destroys her toys. The curious girl stretching those long legs to see what you’re doing. The sweet, smart pup who wants to make you happy and be wherever you are. We have grown incredibly attached to Cheeto and have absolutely showered her with love. Watching her gain weight, feel better, grow stronger, and blossom into the happy, playful puppy she was meant to be has been incredibly rewarding. Cheeto will need a family committed to continuing her special feeding routine and daily medication, but what she gives in return is immeasurable. She is not defined by her medical condition. She is a smart, affectionate, goofy, playful little girl who is so deserving of a family who will look at her and simply see their dog. We know that family is out there, and whoever gets to call Cheeto theirs is going to be very, very loved. www.coloradopuppy.org/how-to-adopt

Takis loves to be with his people. If you sit down, he’ll happily ask to climb into your lap, and we joke that his tail simply never stops wagging — he is just such a happy little guy! He also has the cutest habit of giving you kisses and then leaving just the very tip of his tongue sticking out. It’s impossible not to smile at him. Takis is also a confident, playful pup who loves initiating play with our older, much bigger dogs. Their size doesn’t intimidate him in the least, and he is more than happy to jump right into some good puppy roughhousing! He LOVES his toys, especially anything he can chew, pull apart, and proudly de-fluff. Because of his medical condition, traditional long-lasting chews like bully sticks and yak chews aren't a good fit for him, as they can trigger reflux and regurgitation. Thankfully, Takis couldn't care less as long as he has a basket full of toys to chew, destroy, and investigate. Give this boy a stuffed toy and a playmate, and he is perfectly happy! Takis has also been hard at work on potty training and has been very quick to pick up on going outside. In fact, he has figured out that potty outside = praise and a tiny treat, so he sometimes likes to squeeze out several little pees just to see how many celebrations he can get! We use tiny crumbs of liver treats as rewards, which have worked well for him.
