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. After dedicating herself to motherhood, it's finally Mia Bella's turn to enjoy life, let her personality shine, and find the loving forever home she deserves! ❤️ Mia Bella has made incredible strides in her confidence and has blossomed into such a sweet, affectionate, and playful girl! She's even found her voice and occasionally greets the neighbors with her adorable little "woo-woos!" 🥰 While she may need a little time to warm up to new people and dogs, she's an overall social and friendly lady. Once she gets to know you, she remembers you and will happily greet you with excitement and affection! If there's one thing Mia Bella loves most, it's being close to her people. She's a total snuggle bug who enjoys soaking up attention and spending quality time with her favorite humans. But don't let her cuddly side fool you—this girl knows how to have fun! She loves picking out toys from her toy box and proudly prancing around the house to show off her treasures. Balls and bones are some of her favorites, although soft toys don't stand much of a chance against her enthusiasm! She's a smart girl who understands which items are hers to play with and which are off-limits. Now that her puppies are grown, Mia Bella is embracing her playful side and enjoying some well-deserved fun of her own! She loves going on long walks, exploring her surroundings, and getting some one-on-one playtime with her people. A little rain won't stop this adventurous girl from enjoying her walks, either! 🌧️🐾 After she's had a chance to stretch her legs and burn off some energy, she's more than happy to settle in for some snuggles. Mia Bella is also one smart cookie! She's crate-trained, potty-trained, and does wonderfully relaxing in her crate while her foster is at work. She knows several commands, including sit, stay, and come, and is a great listener. Her adorable wrinkly face only adds to her charm! The one thing she hasn't quite mastered? Posing for pictures! 📸 Mia Bella would much rather run over to the photographer for some attention than sit still for the perfect shot. Luckily, she's absolutely adorable from every angle! Mia Bella has come such a long way, and it's been wonderful watching her confidence and playful personality blossom. She's ready for a family who will continue encouraging her, give her plenty of love and attention, and enjoy all the silly, sweet moments she has to offer. After being such a wonderful mama to her nine puppies, it's finally Mia Bella's turn to be someone's baby! 💕 Could you be the one to give this special girl her happily ever after? 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
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 Gets along with: Dogs?: All dogs; slow intro Cats?: No Meet Poe At approximately 3 years old and 90 pounds, Poe is an intelligent, energetic, and affectionate boy who loves spending time outdoors. Whether he's hiking, swimming, chasing a ball, or simply lounging in the grass, Poe is happiest when he has room to explore and enjoy life. He's the perfect adventure buddy for someone who loves staying active and spending time in nature. Inside the home, Poe is a sweet, devoted companion who loves being close to his people. He'll happily follow you from room to room, stop by for kisses and belly rubs, and settle in nearby when it's time to relax. He's incredibly smart, highly food motivated, and eager to please, making him a rewarding dog to work with. Poe has strong guardian instincts and can be reactive toward unfamiliar people, other dogs, and unexpected activity, particularly on walks or in busy environments. He may bark, lunge, or become difficult to redirect when overwhelmed. However, his foster family has been working consistently on his reactivity, and he's already making encouraging progress. He does best with calm, deliberate introductions and warms up beautifully once he feels comfortable. Poe has shown that he can get along with other dogs through slow, thoughtful introductions, although he remains reactive toward them on leash.  While Poe settles nicely in his crate when his people are home, he will attempt to escape if crated while left alone. Fortunately, he generally does well when given access to a safely dog-proofed home. He's also a determined escape artist who can chew through tie-outs and disregard pet gates, so secure containment and supervision are essential. Poe's ideal home is in a quiet suburban or rural setting with a securely fenced yard and an experienced guardian breed owner. He needs someone who understands reactivity, can confidently manage his strength, and is committed to continuing his training. A peaceful environment, consistent routines, plenty of exercise, and positive reinforcement will help him thrive. Poe may need a little more guidance than some dogs, but he has an incredible amount of love to give. He's playful, loyal, affectionate, and always ready for his next adventure. With the right environment and a family who understands his needs, Poe has all the potential to be an amazing lifelong companion.

Story
Hi, All Mac, here short for Mac truck lol. If you love big goofy dogs, I'm your guy. I am 100 lbs. of cuddle bug. I really don't think I am as big as they say I am because I would prefer to just be a couch Potatoe and lay next to my people and chew on a bone. I am a people kind of guy and love everyone I meet. I can probably live with another dog, but he would have to be calmer like me. but little dogs and very young children I would be afraid of because I am clumsy and wouldn't want to hurt them. I definitely don't think I could handle cats. But I know a lot of commands they say I am really smart and a fast learner. I am potty trained but do not like cages. I am strong on a leash so I would need a strong owner. Fill out an app here. https://docs.google.com/forms/d/e/1FAIpQLSdsHBf5NUtvyBYpzWm6Z5Z0JosLBTsDC98oxPTfxtM9brrc7Q/viewform

Hi my name is Mac. I was found as a stray. they think someone just dumped me off. And my foster mom just found out what a big goofball I am. I have learned all kinds of commands even though I dont use them all the time but I have a good memory. But what I really want is a home to Call my own. I will need a fenced in yard. and a home that is familiar with my breed.
