Story
What are you waiting for? Apply today! Click here to apply for the pet Dumpling is a sweet, easygoing girl who’s totally fine hanging out with other dogs but isn’t really interested in rough-housing or wrestling with them. Her real goofball side comes out with her people – she gets bouncy zoomies and loves to hop around with her humans, but she’s more of a chill companion than a dog-park party girl. From what we know she was raised around older kids, and with proper introductions could be a great match for a calm family home. Dumpling would actually make a fantastic apartment dog: she settles well, and even her bark is quiet and a little comical. If you’re looking for a lower-key buddy who will hang out on the couch, trot along for walks, and make you laugh with her silly little hops, Dumpling might be your girl. We do not have Dumpling's previous shot records and have not updated her vaccines, so she is currently "as-is" meaning any adopter would be responsible for getting her vaccinated. Adoption Fee is $50 We do provide free training. What are you waiting for? Apply today! Click here to apply for the pet

Story
What are you waiting for? Apply today! Click here to apply for the pet Sweetie is an incredibly affectionate, intelligent, and loyal dog. She loves being close to her people, enjoys cuddling, and settles down nicely in the evenings. Through her training, she has learned a great deal and is kennel trained (and is so quiet in her kennel, you may forget she's in there!), she is fully house trained, and is familiar with commands such as sit, heel, climb, bed (kennel), and does well with loose-leash walking, and several other obedience skills. One thing the trainer has consistently emphasized is just how intelligent and capable Sweetie is. In fact, he recently described her as "a dog trainer's dream" and said Sweetie could be great at doing a job, or sport, like agility or dock jumping. She has energy and a vertical leap you wouldn't believe. She genuinely enjoys learning, responds best to structure, and seems happiest when she is being challenged and given opportunities to work, train, and engage with her handler. We believe she would thrive with an adopter who enjoys training dogs and would continue building on the strong foundation she already has. She's happy and... well... sweet. Sweetie gets along best with male dogs. Her adoption fee is $150. She is in a foster home, so contact us for a meet and greet. What are you waiting for? Apply today! Click here to apply for the pet

What are you waiting for? Apply today! Click here to apply for the pet Paco is a rescue from an outdoor pound and we don't know much about his history. He has completed a training program at Modern K9 Solutions, which comes with LIFETIME support. He is a young, small, mixed-breed pup. As of 4/28/2026 - he is HW+ and will be undergoing treatment. He loves other dogs, does great with cats and kids too! Can be a little pushy and tries to hump, but hopefully getting him neutered will take care of that. Takes corrections from the other dogs very well. Lifetime support from Modern K9 is included in his adoption.

Story
What are you waiting for? Apply today! Click here to apply for the pet Linus is about 2-years-old and 45 lbs. Up to date on everything. He is a very good boy and very smart and best of all --- HE LOVE LOVE LOVES OTHER DOGS!!!! He NEEDS to be in a home with other dogs that he can play with. Linus was found locked in a crate in an abandoned home. Poor boy was skin and bones, covered in urine and feces. He has made a full recovery, but with that kind of trauma comes trust issues. Linus does NOT like people greeting him. He needs people to give him space, feed him some treats and build trust first. It only takes 15 minutes and the new person is now his new best friend. The report from the shelter: Like the gentle, kindhearted Peanuts character he’s named after, Linus is thoughtful, sensitive, and truly good at heart — he just needs someone to believe in him. ✨ Linus’ Best Qualities (because there are so many): • Walks nicely on a leash — thoughtful, not chaotic • Gentle treat taker — soft soul, soft mouth • Moderate energy — not a wild Charlie Brown football scene • Very dog-friendly — he LOVES dog friends and they help him feel brave 🏠 Linus is searching for: A home that can offer patience, consistency, love, and guidance. Somewhere he can exhale, settle, and remember that the world can be kind. If you’ve ever loved an underdog… If you’ve ever believed in second chances… If you’ve ever cheered for Charlie Brown when the world seemed unfair… FREE TRAINING IS INCLUDED for any foster or adopter. For questions, please reach out at rescuers@spencerpetrescue.info or fill out our application at spencerpetrescue.info/application. His fee is $150 What are you waiting for? Apply today!

Story
What are you waiting for? Apply today! Click here to apply for the pet Meet this delightful girl who brings a splash of joy and a sprinkle of silliness to everyone she meets! 🌟 Energetic and sweet, she’s the perfect companion for those with active lifestyles. If you love spending time outdoors, she's going to be your new best friend! Whether it’s running around the backyard, playing an exhilarating game of fetch, or joining you on a nice walks, she’s ready for it all! Now, while she’s busy winning hearts, she can be a little shy around other dogs, especially in those bustling dog parks. She prefers the calm of a cozy walk around the perimeter, where she can soak up some socialization without too much pressure. At home, though, she thrives alongside her foster sister, Darla. These two are practically partners in crime, playing and running together all day long! 🐶✨ She does best with playmates around the same size as her and we do not recommend small dogs. But guess what? She’s got a special bond with her feline friend! Yes, you heard that right—they even enjoy snoozing together. How cute is that? Because she's a bundle of energy, older children are recommended; let’s just say she might accidentally tip over a little one with all her enthusiastic greetings! But with a touch of dedication, she can definitely be trained to be gentle. When it comes to her human pack, she’s all about the love! Expect loving tail wags, belly rubs, and plenty of joy when you walk through the door. She’s also a budding guard dog—alerting you to any strangers while you work on her “no bark” command, which she’s picking up like a pro! Just give her some space to warm up to new faces, and she’ll win them over in no time. ❤️ This sweet girl is housebroken and crate trained, plus she adores car rides! 🚗 She’s great with dogs her own size for one-on-one playdates but prefers to steer clear of crowded dog parks. And did we mention her lovely relationship with cats? She can be shy initially, but she just needs a little time to blossom into her beautiful self! Medical update: Yazzy has "bad knees". Doesn't look like anything is torn, but the vet has her on daily carprofen and you'll notice a little limp when she's walking. DNA results: 41% American Pittie 36% American Staffy 9% Akita 4% Norwegian Elkhound 3% Boxer What are you waiting for? Apply today! Click here to apply for the pet
