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!

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
Lilo is a big, sweet-hearted Mastiff who is ready to bring love and loyalty to her forever family! This gentle giant has a calm demeanor and is as friendly as they come. Lilo has been tested with other dogs and did wonderfully, and when walking past cats, she didn’t react at all – so she’s great with both other animals and people. While Lilo may be a little shy at first, her love for human interaction and treats quickly help her open up. She’s a big fan of cuddles and enjoys spending quality time with her people. With some patience, she’ll become your ultimate snuggle buddy and a loyal companion for life. Lilo is looking for a home where she can feel safe, loved, and spoiled with attention. She’s a calm, affectionate dog who would thrive in a household where she’s given the time to adjust and get comfortable. Lilo loves human companionship, and she’ll quickly show you how much she appreciates your kindness – especially if there are some tasty treats involved! If you’re ready to welcome this sweet, giant girl into your heart, Lilo can’t wait to meet you and start her new chapter with you! 🐶💕 All of our dogs are dewormed, spayed/neutered, microchipped, up to date on age appropriate vaccines, and heartworm tested if they are old enough.
