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: Transferred from Skiatook Paws and Claws in Oklahoma at four months old, fixed, UTD on vaccines. *Casey had a series of cluster seizures in foster that resulted in her initially being pulled for medical evaluation. After visits to the ER and a neurologist, she has been diagnosed with an ongoing seizure disorder that requires strict medication administration every 12 hours. It is possible with medication that she will still have breakthrough seizures and potential adopters need to be prepared for more medical needs and financial commitments than the average puppy.* *Casey has been experiencing increased agitation that triggers seizures. Our vet has decided that Casey will need a home without other dogs or children to reduce this agitation and, in turn, reduce seizure frequency. She can absolutely encounter them in her day-to-day, she just cannot live with them.* From the foster: Hi! I’m Casey, and I’m a sweet, easygoing girl who believes life is better when you’re with your people! I love following my humans around, curling up at their feet, or snuggling beside them on the couch. Basically, wherever you are, that’s where I want to be! I’m also a social butterfly! I love meeting people of all ages, from toddlers to seniors, and I enjoy meeting other dogs, too. I have a playful side and love romping with my foster dog sibling, although sometimes I get a little carried away and need a reminder to take a break. I’m a smart cookie and already know sit, down, sit pretty, shake, and come I’m working on place and stay, and I even know not to dash through the gate when I’m told to stay in the yard. I’m still working on my house training and puppy nibbling, but I’m making great progress with both! Walks? Absolutely! I’m a dream on leash and love exploring the world with my foster family. When we’re home, you can usually find me having a blast playing fetch with my squeaky ball. A good game of fetch followed by some couch cuddles sounds like the perfect day to me! I do have one important medical need my forever family will need to understand. I have a history of seizures, which are currently well controlled with medication twice a day. I will need this medication for the rest of my life. My family will need to be committed to my ongoing care, and in return, I promise to fill their lives with plenty of love, laughs, walks, squeaky-ball games, and cuddles. My dream home would be a calm household—preferably with older children, if any, because I’m still working on my puppy nibbling. A mature, calm doggy sibling would be wonderful, but I’d be happiest being your one-and-only. If you’re looking for a loving little shadow with a playful heart, a passion for walks and squeaky-ball fetch, and LOTS of love to give, I just might be your girl! I’m Casey. Come meet me—I think we could be pretty great together! www.coloradopuppy.org/how-to-adopt

Story
Meet Poppy! He is an energetic & young border collie (?) mix. We have been fostering him since Friday and have learned a little bit about his spunky personality.  Poppy enjoys zooming around in the backyard and going for walks in the neighborhood. When he isn't zooming, he is taking toys out of the toy bin and decorating the living room with them. Thankfully, he gets along well with our hound & loves to run circles around her. He is so, so fast! At this time, he doesn't know any commands and is hit or miss with his meals. Since he is a herding breed, he does nip while trying to herd people which can be scary for younger kids. Whoever ends up adopting him should definitely invest in a trainer that has experience with herding breeds. Poppy will definitely make a great adventure dog with all of his energy and spunk. To meet Poppy, please fill out the adoption application at Trevorsanimalrescue.com ##2836256##

Story
0826035 - Meet Raven, a beautiful 1.5-year-old Border Collie mix with a heart as big as her personality. If you’re looking for a constant companion, you’ve found her—Raven is a total "lap dog" who would love nothing more than to be curled up right in your lap at all times. She is incredibly gentle, affectionate, and truly wants to please her people, making her a wonderful, devoted addition to any home. She is easy to have in the house- crate-trained and house-trained with a consistent routine. She’s a dream on a leash, making walks a relaxing experience, and she plays well with other dogs, so she would be a great fit for a multi-dog household.  While she is a happy and confident girl, she does find some new things a bit scary and appreciates your patience as she figures it out.   Raven is a sweet, loyal soul waiting for her perfect match. If you are ready for a lifetime of snuggles and a best friend who will always be by your side, please submit an application at www.SloppyKisses.org/adoptions! ##2837904##

0726032 -   Hello! It’s cutie pie Sully here, and I’m ready to find my forever home. Could you be the person—or family—I’ve been waiting my whole life to love? When I was abandoned as a puppy, I didn’t know what my future would look like, but I’ve always hoped for someone who would help me learn, grow, and become the best boy I can be. I’m a quick learner (my foster parents will happily confirm that!), but I’m still working on my puppy manners and would love someone patient and kind to guide me. I absolutely adore being around my humans. I love pets, enjoy going on walks, and sleep very well in my crate—as long as you’re in the room with me. I get lonely at night and feel safest when I know you’re close. I’m great with the doggie door, and I’m learning not to mark in the house. I’ve already made huge progress in just a week, so I know I’ll master it soon. As you can see from my photos, I’m a playful guy. I love toys, zooming around the yard, and playing with my foster siblings. I currently live with a bossy chihuahua, a shy shepherd mix, and a very boring pit bull mix—and I get along with all of them! I also love people, including kids, and I’ve been friendly with everyone who has visited my foster home. I’m a total love bug who just wants attention, affection, and a family to call my own. If you’re looking for a sweet, playful, affectionate pup who’s eager to learn and even more eager to love, I’d be thrilled to meet you.  Fill out an application at www.SloppyKisses.org/adoptions! ##2811556##

Story
Meet Bottle Rocket Bottle Rocket came all the way from New Mexico, and he’s ready to blast off into his forever home! This sweet cattle dog mix may be named after something explosive, but his personality is wonderfully calm and gentle. He loves snuggling up with his people, relaxing in your arms, and soaking up affection. When playtime rolls around, he enjoys wrestling with his brother before settling back down for another cuddle. Bottle Rocket is a smart little guy who is doing well using potty pads and is continuing to work on his potty training. He is also very respectful of the older dogs in his foster home and seems to understand when they want their space. He’s not burning out his fuse up here alone—he’s patiently waiting to find the family who will love him to the moon and back. If you’re looking for a calm, clever, affectionate puppy who is equal parts playful and cuddly, Bottle Rocket may be the little “Rocket Man” for you.  Adoption fee includes the following: Spay/Neuter Rabies Vaccination Distemper / Parvo Vaccines (includes series of 3 for puppies) Bordetella Microchip with prepaid lifetime registration Deworming ##2795244##

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: Brought in as a stray and initially aged at 5 months old, but after reviewing prior records, it was determined he had been neutered 2.5 years ago and was re-aged accordingly. Transferred from Operation Kindness in Texas. *Koda does not attend adoption events unless there is a confirmed potential adopter who would like to meet him. Please email info@coloradopuppy.org to plan a meet and greet.* From the foster: **UPDATE July 1st: Koda was adopted briefly, but never fully settled into his adoptive home; upon one of his humans leaving for a trip, the second human attempted to leash him for a potty break and he became terrified, ultimately fear-biting them. Koda went back to his foster home the next day and has begun to re-acclimate. He is still struggling with leashing, is most successful when free-roaming his fenced yard, and with other dogs. We think he'll be most likely to open-up in an adoptive home that has both of those things, and his adopters should be prepared to give him ample time to feel comfortable and seek attention on his own timeline. Update from new foster on 8/29: I’ve had the pleasure of having Koda with me since last week - he is such a special little guy! What we expected from the foster shift: Koda to be standoffish at best and probably a do bunch of hiding at least until he got acclimated to the new environment. What we got instead: instant best friends with my 2 dogs, and he slept snuggled up against me the first night. Things aren’t always smooth sailing, he still flinches if I move too fast or raise my voice, but where he is now compared to how he was a few months ago is like night and day. Koda’s perfect home would have a big fenced yard, and at least one doggy sibling who likes to wrestle and run. Koda and my 4 month old Cattle dog mix spend HOURS a day hard at play, often joined by my 3 year old Shepsky for full contact Puppy Palooza! Koda is still learning to trust men, and small children make him nervous, but show him patience and love he just melts into a kiss -giving, tail-wagging, snuggle bug. Koda is well on his way to learning that there really are some wonderful people in the world. He is totally going to end up being somebody’s soul dog… is it possible he’s yours? Bio from Koda’s first foster: This is Koda. He is seeking a very loyal long-term best friend and pack of his own. Koda is blossoming into a happy and playful pup. With lots of love and consistency, he will be a brand new guy! He may need to explore the world in his ThunderShirt and get carried around occasionally but he will look darn cute doing it. He’ll need a lot of time in his new home to adjust. Koda’s new home should expect double the decompression and adjustment period. Every small ounce of personality will be worth the wait, and an enthusiastic best friend will be waiting for you. Strengths: ✅ Smile that lights up a room ✅ Crate trained ✅ Potty trained ✅ Sleeps through the night ✅ Routine ✅ Playing with toys ✅ Chewing on bones Needs: ✅ Dog Friends ✅ Fenced Yard ✅ Kennel/Crate for comfort ✅ All the patience Extra Time Required: ✅ New people ✅ Leash walking ✅ New spaces Extra Extra Time Required: ✅Men www.coloradopuppy.org/how-to-adopt
