Story
Alert! Big dog lovers, we have the perfect Tall dog for you! Enter: Joan Crawford, our 155 pound, 5 year old, Mastiff! This beautiful lady joined TNT as a breeder release and she is currently acclimating to life inside a home. So far, Joan has been incredibly calm and takes her time observing her new surroundings, including resident dogs and cats in her foster home. She’s still getting the hang of basic things, like crate/potty/leash training, but with encouragement she can be convinced! Joan will need a patient home with adopters who have experience with large breed dogs. Her ideal people will move at her pace and enjoy watching her progress toward learning to be a family dog. We promise, it will be so worth it to see her blossom! Joan Crawford's adoption fee is $550 which does include the cost of her gastropexy

Story
Meet Mia Bella! 🐾 Mia Bella is a beautiful 2-year-old Boxer/Mastiff mix weighing 66 pounds. This sweet girl came to Anderson Humane from a partner shelter in Louisiana alongside her nine puppies. Now that her puppies are growing up, it's finally Mia Bella's turn to find the loving forever home she deserves. Mia Bella is a gentle, easygoing companion with a heart full of love. She may take a little time to feel comfortable with new people—especially men—but once you've earned her trust, she'll be your biggest fan. Cuddles, affection, and spending time by your side are some of her favorite things, and her serious expression is simply deceiving—deep down, she just wants to be your best friend. This lovely girl enjoys treats, toys, and relaxing outside, soaking up the fresh air at her own pace. She's crate-trained, potty-trained, and wonderfully quiet, making her an easy addition to the home. Mia Bella is also a fast learner who loves to please and is already making great progress with cues like sit, paw, down, and stay. If you're looking for a loyal, affectionate companion who will reward your patience with endless love and cuddles, Mia Bella is ready to steal your heart. When Mia Bella arrived at Anderson Animal Shelter, she tested positive for Heartworm. The staff believes that the best place for Heartworm-positive dogs like Mia Bella to recover and complete treatment is in a loving forever home. If you choose to adopt Mia Bella, our clinic staff will support you every step of the way by answering questions and providing guidance throughout her treatment. The process generally takes about three months and involves some simple at-home care to help keep her safe while she recovers. The final step is a follow-up test six months after treatment begins. The Heartworm treatment process is highly successful, and the staff anticipates that Mia Bella will make a full recovery! It's also important to know that Heartworm can only be transmitted from animal to animal through mosquito bites. If you're looking for a gentle, affectionate companion with lots of love to give, Mia Bella is ready to meet you! Stop in and meet my cute self in person during our adoption hours. For more information, email info@ahconnects.org or call us at 847-697-2880 x: 0, and the staff will be happy to help you. All of our dogs and puppies go home spayed or neutered, microchipped, and heartworm tested (for dogs 7 months and older). They are also up to date on core vaccines, as well as heartworm, flea, and tick preventatives. Each adoption includes a 3.5-pound bag of dog or puppy food and a free vet exam at one of our participating veterinary partners.

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.

Story
Hi, I’m Poe and I’m ready to find my forever home!  Dog’s Name: Poe Location: Oak Park, IL Date of Birth: 5/26/2023 Gender: Male  Breed: Mastiff Color: Brown Dog's Weight: 81 Gets along with: Dogs?: No Cats?:  No Kids?: No. An adult home is the best fit for Poe. Training: Potty Trained: Indicates a need to potty and doesn't have indoor accidentsCrate: Goes into his crate when asked and settles well overnight; however, Poe can break out of a crate when left home aloneCar: Happily hops in the car and is always ready for an adventureTraining: Highly food motivated, eager to learn, and enjoys enrichment games and working with his person Meet Poe! Have you seen this face?! Seriously. Those puppy eyes. That smile. The kisses. Poe is an 81-pound bundle of brains, athleticism, energy, and absolute devotion to his person. Inside the home, Poe is a total sweetheart. He wants to be near his people and will happily follow you from room to room, frequently checking in to give you a kiss, collect a few pets, and make sure you're still aware that he is, in fact, adorable. His foster describes him as fun, strong, smart, athletic, and eager to please. Poe LOVES to learn. He is highly food motivated, enjoys enrichment games, and lights up when he has something to do. Whether it's learning a new skill, exploring outside, or heading out on an adventure, Poe is the kind of dog who wants to engage his brain and body. And if you open the car door? Poe is in. This boy is always ready to go somewhere and would make an incredible adventure or sporting companion for the right person. But here's something important about Poe: we don't think city life is his thing. Poe is currently fostered in a busy urban environment filled with people appearing from doorways, slamming car doors, motorcycles, ambulances, runners, skateboards, kids on e-bikes, and constant activity. For a dog with strong guardian instincts, that's a LOT of information to process.  His foster has noticed something incredibly important. Poe is a completely different dog in quieter environments. Away from the constant sights and sounds of the city, Poe is able to relax. His guardian brain doesn't feel like it needs to monitor every person, noise, and unexpected movement around him.  That's why we're looking for something different for Poe. A quieter suburban or rural home. A securely fenced yard where he can sniff, explore, play, and sunbathe. A person who enjoys being active and wants a dog by their side. Someone committed to continuing his training. And someone who understands the deep loyalty of a guardian breed. Poe is reactive to other dogs and can react to unfamiliar people or unexpected movement when he feels surprised or crowded. He needs deliberate introductions to new people rather than strangers simply walking up to him. But here's the part we really want people to hear: Poe is already improving. He can now see a dog from about half a block away without reacting. He is reacting less and less to people. His foster has been helping him learn to self-regulate, and Poe is beginning to show that he can make different choices. And despite the big watchdog bark? Poe actually enjoys meeting new people. Give him a thoughtful introduction and a moment to understand that someone is safe, and this sweet boy warms up quickly and loves generously. At home, Poe's guardian instincts make him an excellent watchdog. He may alert his people when he sees or hears something suspicious, but he isn't an excessive barker. Once his person acknowledges the situation and tells him, "That's enough," Poe settles back down. Poe isn't looking for a busy city apartment or a packed neighborhood where every walk feels like rush hour. He's looking for room to exhale. A yard to sniff. A sunny spot to stretch out. A person who thinks training a smart, athletic dog sounds fun. And a home where he can finally stop watching the entire world and focus on loving his person. Because when Poe loves you? He checks in. He follows you. He gives kisses. And he looks up at you with those ridiculously sweet puppy eyes that his foster says will absolutely melt you.  Poe needs an experienced adopter who understands powerful guardian breeds and is committed to continued training. He must be the only pet and would do best in an adult home. But for the right person? Poe may be the adventure buddy, training partner, watchdog, professional kisser, and fiercely devoted best friend you've been looking for. Maybe this sweet boy hasn't been overlooked. Maybe he just hasn't reached the right person yet. Could that person be you?
