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

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.June 10, 2026, 12:03 pm

That is what Benjamin and his partner Olive looked like when we took them home. Benjamin is a sweet JRT mix that is about 2 years old and weighs 27 lbs. He loves to play and destuff all of his stuffed animals. When his energy runs out, he will snuggle next to you on the couch. He is a smart boy and will keep you on your toes. Benjamin is learning house manners and will stay in a crate. Benjamin walks well on a harness but beware of squirrels. Because of his high prey drive, absolutely no cats!!! A fenced yard is highly desirable but not a necessity. he can always go out on a leash but never off leash when not in fenced yard .

Please email critter cavalry rescue at ccrnewengland@gmail.com. please inform us where you live, city and state since we R based in Tennessee.

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. June 11, 2026, 1:13 pm

Gemma

Rat Terrier

Female, 9 yrs

Rockville, MD

Size

(when grown) Small 25 lbs (11 kg) or less

Details

Not good with kids, Good with dogs, House-trained, Spayed or Neutered, Shots are up-to-date,

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
