Story
6 years old (estimated) Neutered Male  106 lbs. Has done well with other dogs  Looking for a home without cats  No known experience with kids  Meet King, an extra-large teddy bear with an even bigger heart! This handsome boy loves attention and is happiest when he's spending time with his people, soaking up pets and showing off his signature big smile. King enjoys exploring the outdoors, especially when he can take his time sniffing around and checking out all the interesting scents along the way. He also likes going for walks, although King prefers to keep them on his own terms. When he's decided he's had enough, he'll happily sit down and anchor himself right where he is, letting everyone know the adventure is over for the day. With his lovable personality, laid-back attitude, and charming grin, King is sure to bring plenty of smiles and laughter to the lucky family who welcomes him home. King's adoption fee had been paid by a generous member of our community! The online adoption listing websites require that we choose a predominant breed or breed mix for our dogs. Visual breed identification in dogs is unreliable so for most of the dogs we are only guessing at predominant breed or breed mix. We encourage you to select your new companion by considering each dog's individual personality and pet qualities instead of relying on a breed label that is only a guess.July 21, 2026, 10:36 pm

Story
I am 53 lbs, and I am looking for my forever home. Adoption Donation: $450 Shy is a beautiful girl with a stunning brindle coat and a gentle, sensitive soul. True to her name, she can be a little shy at first and may need a minute to warm up to new people. But once she feels safe, her sweet personality shines through. Shy loves affection and will happily lean into you for pets once she trusts you. She has such a tender heart and just wants to be close to someone who cares about her. She came to us when her owner sadly became homeless, and the change has been scary for her. Shy is simply looking for a safe, loving home again — a place where she can relax, feel secure, and be someone’s beloved companion. With a little patience and kindness, Shy will reward you with quiet loyalty and lots of love. All dogs are microchipped, neutered, current on all vaccines, heartworm tested (if age appropriate), and up-to-date on preventatives at the time of adoption. All household members and any dogs from the household need to be present to be able to adopt. A photo ID will be required at the time of adoption. Appointments are recommended. All applications are considered general. Specific animals are NOT put on hold for adoption. When you visit, our adoption counselors will be able to make suggestions based on the type of pet you are looking for and help you find the best fit for your family. Animal House Shelter cannot guarantee the breeds of the adoptable animals. The animals are posted on the website as the breed or breed mix based on their physical characteristics they most resemble. We also cannot guarantee the ages of our adoptable animals or how large puppies will be when fully grown. We look forward to seeing you soon!

Not good with kids, Good with dogs, Spayed or Neutered, Shots are up-to-date,
Story
Meet Sam! Sam is a very handsome pup, estimated at about 3 years old. He’s thought to be a Mastiff Mix, but, rather small for the breed. Sadly, Sam found himself at an overcrowded noisy animal control facility down south. He deserves a forever home and family of his own, and we want to help him get there!! This precious pup absolutely loves people and is good with older kids who are respectful of dogs. We expect he is good with lower energy dogs. Dogs who are too active might scare him and cause him to react. Sam absolutely loves belly rubs, and treats too! He's a little rough around the edges in terms of training but clearly is eager to learn. Sam is in overall good physical shape however he does have some vision issues causing him to sometimes miss things coming his way….this is why we expect he’d be scared by higher energy dogs, and high-activity youngsters. Sam is neutered, up to date on vaccinations, microchipped, heartworm negative and on preventative. We would still like to get Sam to an eye specialist for a comprehensive examination of his eyes/vision. If you’d like to add Sam to your family, please contact BAARKDogRescue@gmail.com or 847-852-0895.

Story
Oh, Leona....where do we start? It is evident that this poor girl was loved at one point in her short life. She knows how to sit on command, give paw, and does zoomies when she's excited. We're not sure where things went wrong for her, but she's with us now and is learning to trust again. She's on the petite side and is so funny when she plays. She, unfortunately, is not a fan of other dogs so she'll need to be the only one in the home. Email us at bombshellbullies@hotmail.com to see if Leona would be a good match for you!
