LOCATION: Linden, VA Chip's adoption fee is fully sponsored — lucky pup! 🐶 Meet Chip! Chip is a fun-loving, energetic pup with a big heart! Whether he’s chasing a ball or entertaining himself with his toys, Chip brings a playful spirit and joy to everyday life. He also loves baths! Chip may take a little time to warm up to new people, but once he feels comfortable, his affectionate and loyal personality shines. He forms strong bonds and loves being close to his people—whether that’s relaxing on the couch or lying at your feet while you work. He will thrive in a home that offers structure and encouragement where he can continue building confidence. • Secure yard: Chip loves having space to run and play freely. • Exercise: He’s an active pup who benefits from regular playtime. He’s improving on leash walks but can still be a little fearful in new environments. • Companions: Chip has done well with other dogs, from calm companions to rough-and-rowdy playmates. He is also good with cats! • Crate trained: Chip does well in his crate and settles nicely, sometimes putting himself in for naps or chew toy time. He sleeps through the night and does not have crate accidents. • Potty training: Chip is getting much better with potty training, and will need continued consistency and routine to help him master it. • Toys: Chip has experienced a lot of change in his short life so far and can sometimes be protective of toys or high-value items, but he responds well to trades and positive reinforcement. • Kids: Chip does well with older children who can respect his space and help him continue building confidence. Are you Chip's hero? If so, apply to adopt today!

Story
We will never know Raya’s past, but she came to us from the shelter as a stray with urine stains on her fur and recently healed scars on her head and side. Raya is believed to be around 4 years-old and is probably a mix of rat terrier and chihuahua, now at a good weight of 9.5 lbs.! She had her spay and a small benign mass removed from her left armpit shortly after arriving, and saw specialists to address extreme pain during bowel movements. Finally, in November 2025, she had double knee surgery to correct her painful injuries. Although Raya has healed well she will probably remain a little lame on her right rear leg but that doesn’t stop her at all! She is back to going up and down stairs, can now get up on the sofa by herself, and is even dancing for her breakfast! Although she has mostly done well with the other resident dogs, she has displayed signs of resource-guarding with her crate. These behaviors might be related to the physical scars she has and her experience with other dogs prior to the shelter, so she would do best in a home with no children or dogs. Although she can be a bit barky at people and dogs when out walking, she is very treat-motivated and can easily be redirected. When introduced to the resident cat, Raya did not seem interested. Even though Raya does not ask to go out, she is reliably house-trained on a schedule. Raya is cute as a button, recovered from knee surgery, and is ready to start looking for her forever home. Considering Raya’s past, she would do best in a home where she would get all the attention and not have to share her human(s). You can see more of Raya in her online photo album at https://imageevent.com/newrattitude/raya Because of her past injuries and recent surgery, we are looking for a local adopter to be able to meet her and learn more about her! If you are interested in adopting this dog, PLEASE READ THE DETAILED ADOPTION PROCESS information on our website at www. NewRattitude.org/adopt/  From there, you can access our adoption application or contact our Adoption Team for more info.March 9, 2026, 11:01 pm

Story
Hi, I'm Levi and I just landed with my new foster. Unfortunately, I was given as a gift to someone who was not able to take care of me. I'm a friendly, fun little puppy with lots of energy - I like people and other dogs, and I'm young enough to learn and be a good citizen! I would do best in a home with a yard, and with folks who are willing to take time to exercise and socialize me! Puppies need a lot of attention - so if you are able to keep up with me, apply today! Hatton Animal Rescue spends significantly more on each dog than the adoption fee covers; please consider making a tax-deductible donation by visiting us at https://www.hattonanimalrescue.org/sponsor. Donations help us offset vetting, boarding costs, and additional medical treatments for dogs who need it. For more information on Hatton Animal Rescue, visit our website at: hattonanimalrescue.org.

You can fill out an adoption application online on our official website.All of the animals posted on our site have been temperament tested. While not all are in the immediate area, once we have processed and approved your application, we will move the dog to our adoptive area for you to meet, greet and hopefully adopt. Sometimes we will have more than one application on a dog. That does not mean it automatically goes to another family but you should be aware of the fact that until you are approved and set up for the meet/greet.. the dog could get adopted by another applicant.Oh so small in size, but big with life and love, Milkshake loves to play and at barely a year old should have a long life to prance at your side and play with you happily in the yard, the park, or anywhere you want to go. If you go there, she will be overjoyed to be at your side. At only 13 lbs., she will fit well into a backpack or a front snuggly. Extra outgoing and friendly, she loves the whole world. For you, of course, she will reserve a very special love that will last a lifetime and then some. You can count on her to greet your friends with tail wags.  If you want to bring warmth, joy, and happiness into your life, Milkshake is your girl. Come meet her and see for yourself. Milkshake is working on housetraining and will need continued training with leash and harness. She didn't have any training in her previous home. NOTE:  Milkshake has some crate anxiety when left alone, so she needs to go to a home with another dog and a person who is home most of the time. A fenced yard is required because she still has a lot of puppy energy. If you are interested in Milkshake, please fill out an application at: https://reachoutrescue.rescuegroups.org/forms/form?formid=4588    Or contact: rorrcanine@gmail.com   *** Click here to sponsor this dog! ***Visit this organization's web site to see any additional information available about this pet.July 22, 2026, 10:51 am

Story
Best friend Buddy is the total package. He loves people and greets everyone, always eager for attention.   At 12, Buddy ended up in a rural Tennessee shelter. We do not know his backstory or why such a sweet boy would land in a shelter. We may never know.     At Critter Cavalry, we adore seniors and believe they deserve every chance to find a loving home. You won’t regret considering Buddy—he loves everyone, whether human or animal. Buddy is everyone’s best friend.     Buddy is healthy for a senior. He has limited sight and hearing, but is otherwise in good shape. He navigates his foster home easily and enjoys exploring the fenced yard. He comes when called—just use a louder voice.   Buddy is ready to retire with a couple eager to add him to their family. He’d love a fenced yard to explore—size isn’t important—and an active retirement with short walks and car rides. He will be a wonderful addition to a family that matches his lifestyle.   If you want a new best friend, Buddy is perfect for you. To learn more about adopting him, contact Vivienne at vivienneajames@gmail.com or 615-943-7311. Approved application and adoption fee required.    July 22, 2026, 4:43 pm

Story
Meet Gemma. Part couch potato, part tiny queen, part weather critic. Gemma is a 9-year-old Rat Terrier mix with a soft heart, a love of routine, and extremely strong opinions about wet grass. If the lawn is damp, she will do everything in her power to avoid touching it — a level of dramatic commitment that her foster both respects and fears. At home, Gemma is affectionate, loyal, and happiest curled up beside her people enjoying a quiet day indoors. She loves snacks, cuddles, calm environments, and getting your full attention. Her foster says she has the sweetest little whine when she wants more affection, which is often because Gemma firmly believes cuddling is a full-time job. She’s crate trained, low energy, walks nicely on leash, and gets along well with calm dogs and cats. Excitable dogs who invade her personal space, however, are not her thing. Gemma prefers a peaceful home where everyone respects boundaries — especially during mealtime. She does guard her food and needs a family who will simply feed her separately and leave her alone while she eats. With that easy management in place, Gemma settles beautifully into home life. She’s also not a fan of being picked up, so her ideal adopter will understand that love sometimes means meeting a dog where they’re comfortable and letting trust build naturally. Because of this, Gemma is looking for an adult-only home without children where she can feel safe, understood, and relaxed. Gemma is looking for a quiet, stable home with soft places to nap, predictable routines, and people who appreciate a slightly opinionated little dog with a huge capacity for love. We just welcomed 9 year 13 lb female rat terrier mix Gemma. Fostered in Gaithersburg, MD Please apply at mirishaven.org

Meet Vulcan! 🐾 Vulcan is a sweet and sensitive little Terrier/Rat Terrier mix who just needs a little time to warm up to new people. While he can be a bit nervous at first, once he trusts you, he becomes the most loyal companion and will happily follow you everywhere.

Story
Current Location: Ijamsville, MD Adoption Fee Covered + Free Training! Thanks to a generous supporter, this pet's adoption fee is fully covered — and OPH is including six virtual training sessions with a certified trainer in the first 60 days to help you start off strong together! Meet Macaroni: The Sweet, Shy Soul Ready to Blossom If you have a quiet home and a heart full of patience, Macaroni might just be the missing piece of your family. A survivor of a challenging past, Macaroni is learning that the world isn’t quite as scary as she once thought. While she is still discovering the simple joys of life, she is proof that with time and kindness, even the shyest dogs can show their true colors. The "Real Talk" on Macaroni Macaroni needs an adopter who respects her pace and understands that her progress is measured in small, beautiful moments: Earning Trust: Macaroni is not a "lap dog" in the traditional sense. She is still very fearful of direct touch; however, when she feels safe she’ll tentatively seek out chin scratches or give you a gentle "boop" with her nose when you aren't looking. She needs a home that will give her the space to approach you on her terms. The "Ignore" Rule: She is cautious around new people. Her way of managing nerves is to bark from a distance or retreat if someone tries to engage too quickly. She does best when visitors simply ignore her, allowing her the dignity and safety of deciding when to say hello. Potential Flight Risk: Macaroni is still adjusting to the concept of boundaries. She currently dislikes the leash and has shown a knack for jumping fences when overwhelmed. Because of this, she needs a secure yard and an adopter who understands her flight risk until she is fully bonded and confident in her surroundings. (The good news? If she does wander, she’s so attached to her people that she naturally gravitates right back.) Why You’ll Want Her on Your Team Once the "shell" comes off, Macaroni is a delight. She is not just a project; she is a personality waiting to shine: The Wiggle-Butt Factor: When she’s happy, she does the cutest, most infectious wiggle-butt dance. If you talk to her, she’ll light up, showing you the silly, playful side that has been waiting to come out. Morning Zoomies: Nothing beats the sight of Macaroni enjoying her morning zoomies in the yard. She’s learning how to play, how to chase, and how to be a dog. A True Friend: She loves her canine best friend, Cheese. Watching her blossom alongside him has shown us that she has a massive capacity for love—she just needs the right environment to let it out. The Perfect Match Macaroni is looking for a home that can offer: A Canine Mentor: She must have a confident, balanced dog in the home. She relies on other dogs to show her the ropes and help her feel secure enough to be herself. A Low-Traffic Environment: Because of her fear of strangers, she would thrive in a home with adults or older teens who can respect her need for space. Patience and Security: An adopter who is committed to a "safety-first" approach regarding leashes and fences, and who understands that she needs time to settle in before she truly reveals her full, playful personality. Are you the patient, steady hand Macaroni has been waiting for? She has so much love to give to the right person. If you're ready to provide a sanctuary for this sweet, wiggly girl, please click the apply button today! We would love to see Macaroni and Cheese find their forever home together. If that isn't possible, she still requires a home with another confident dog to help her navigate her new world.
