Story

Sherman (aka Shermie or Sherm) is a handsome little rat terrier mix with a heart full of love. Rescued from a busy shelter where he was too nervous to shine, he's now thriving in foster care in Northern Virginia and showing his true, gentle spirit. About 2–3 years-old and 15 lbs., Sherman is sweet, sensitive, and playful. He may need a little time to warm up to new people, but once he trusts you, he becomes a deeply loyal companion who loves being by your side. He enjoys other small dogs and has a submissive, easygoing play style. Sherman would do well with a confident canine buddy — or as an only pup soaking up all the attention. He'd really thrive in a home where someone is around most of the day. Though he can be a bit skittish when first being leashed, he quickly relaxes and truly enjoys walks, car rides, and playdates with his small dog friends. Sherman is progressing nicely with house-training and does well on a consistent schedule. He has gotten along well with cats but has not been tested with children. Due to his sensitive nature, he'd likely do best in a calm home without young kids. With patience and love, Sherman will blossom into a devoted little shadow who bonds deeply and gives his whole heart.

Raya (MD)

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!

Story

Adopt-a-pet Inquires are not an application and will be ignored. Looking for a Foster or Adopter Rue is approximately 10 months old and fully grown at 20lbs. This sweet girl is playful, smart, and 100% a clown. Learning new things is what she excels at! She loves her walks and boy does she also like to run around, as in chase me if you can to the fastest of dogs :) She gets along with dogs of all sizes, cats and of course humans. Kids unknown. She’s not a barker, social yet happily independent. Crate trained. Rue needs an active family. She will be a tripping hazard for the elderly and folks with mobility challenges. At some point right after she was born, Rue experienced some kind of trauma causing a neurological deficit that manifests in an abnormal gate which is not noticeable unless you’re looking for it as well as needing structured potty time. We do not believe she is need of further assessment but potential adopters should discuss Rue with their veterinary professional.

Meet MINNIE! Sweet Minnie is about 5 years old, 25 pounds, female, black and tan rat terrier mix. She is so sweet and a friendly gal! She loves to get attention from her humans! Everyone she meets adores this sweet girl. While she is a tripod, Minnie does not let that hold her back -- she can be energetic, and loves playing in the yard and with her toys in the house! After a walk, Minnie settles down for a nice nap or just to hang out with her people. She has done well with cats in her home. Minnie has great house manners, including being housetrained. Poor Minnie has not always been properly taken care of but has left her horrible past behind and is ready to find her forever home. When found by animal control in NC, she had a painful leg injury. Despite the pain, she was so sweet that the shelter made an urgent plea to save her....PetConnect Rescue was able to come to her rescue, bring her to the DC area to a great foster, and give her the necessary medical care she needed, including amputation of the irreparable leg! Although she is a tripod, she has so much love and happiness to give to her new family for many years! Minnie would love to curl up in your lap to hang out on a spring evening; she loves to cuddle and get pets! Minnie is up-to-date on vaccines, preventatives, and has had bloodwork, a dental, and heartworm treatment! She is eager to find her person(s) to love! ***Please note that our first step is to fill out an application (it does not commit you in anyway but allows us to discuss with you if you and the dog are a good fit). In addition, an important step in approving adoption applicants is to complete a vet check to ensure that your current and previous pet(s) are kept up to date on vaccines (including rabies ), spayed or neutered, maintained on appropriate monthly preventatives and examined annually by your vet.*** The adoption fee for this dog is $425 which includes routine vetting and spay/neuter. PetConnect Rescue cannot guarantee the exact breed of any animal in our care. The breed listed is based on any background we may have been provided, and the general appearance of the animal at the time they enter our system.
