Story
Hi, I’m Delilah.  I'm still recovering from TPL surgery, but I'll be ready for my forever home soon.  Please click adopt to get your application approved.   Name: Delilah Location: Lake Station, IN Date of Birth: 02/01/2024 Gender: Female Breed: Neapolitan Mastiff Color: Black  Dog's Weight: 116 Gets along with: Dogs?:  Very dog friendly, but needs a slow introductioin to dominate dogs Cats?:  We have had multiple interactions and though she might be interested in a chase,               she is good with cats. Kids?: Not yet Training: Crate/Kennel:  Goes into crate/kennel on command She has made HUGE strides on car rides and she is good on least...most of the time. Meet Delilah! Delilah is a deeply loyal, sensitive soul who forms bonds that are nothing short of extraordinary. She may not be the type to greet you with instant kisses—but when she chooses you, she chooses you completely. Delilah does not trust easily, especially with men, and she will need patience, understanding, and a calm environment to feel secure. She relies heavily on her crate as her safe space and is 100% dependent on it to decompress and feel protected. For Delilah, her crate isn’t just a training tool—it’s her comfort zone, her retreat, and her security blanket. But here’s the beautiful part: once Delilah decides you are her person, the transformation is incredible. It’s not gradual. One day she may still be unsure… and the next, she trusts you completely. And when she trusts you? She gives her whole heart. She currently trusts three people and treats them all equally—with full devotion. She happily sleeps upside down with her head on her trusted human’s chest, snoring contentedly for at least an hour each day. It’s her way of saying, “You’re mine, and I feel safe.” Delilah loves squeaky toys (the squeakier, the better!), gentle attention, food, and being close to her humans Delilah’s perfect adopter is some who understands that love like hers is earned—and so worth it.  They must be patient, unwaivering trust that this is a non-violent fear, and be committed to socializing her slowly and responsibly - using a muzzle for portection while she builds confidence.  Delilah loves unconditionally, but she needs patience to get there. She is not reactive out of aggression; her hesitation comes from fear and uncertainty. With consistency, structure, and compassionate leadership, she blossoms beautifully. A good, confident fur-buddy (or even two or three!) certainly wouldn’t hurt. Having stable canine companions can help her continue building confidence in a safe and supportive way. Delilah isn’t for everyone—and that’s okay. She’s waiting for someone who sees past the fear and into the devoted, snuggly, upside-down-sleeping sweetheart she truly is. And when she finds her person, she will love them with everything she has. Until the profile is removed from the public’s view, this dog is considered available for adoption.

Hi, I’m Sven.  I’m not quite ready to be adopted.  I'm on a medical  hold awaiting medical treatmet.  Soon I'll be ready for my forever home so please click adopt to get your application approved. Dog’s Name: Sven Location: Naperville, IL Date of Birth: 10/28/2025 Gender: Male Breed: Great Dane Color: Black Dog's Weight: 45 Gets along with: Dogs?: All Dogs  Cats?:  All Cats Kids?: All kids Training: Crate/Kennel:  Goes into crate/kennel on command Potty trained: We're working on it Car:  Rides Well in car Meet Sven – Your Sweet, Playful Best Friend! Sven is a lovable puppy with a heart as big as his paws! This sweet boy is all about the simple joys in life — tasty treats, chasing balls, and proudly carrying around his favorite plush toys (which he has impressively not destroyed!). He has a gentle, playful spirit and is learning all the fun things that come with being a growing pup. Sven absolutely loves other dogs and thrives in canine company. As a young puppy, he’s still learning about the world and will need continued socialization to help him grow into a confident, well-rounded adult. He’s eager, curious, and ready to soak up new experiences with the right guidance. Because Sven was treated for Parvo on 2/23/26, he will need careful socialization and should avoid public spaces for four weeks while his immune system continues to strengthen. After that, he’ll be ready to safely explore more of the world with his family. The good news? Sven is wonderful with kids and other dogs! His friendly, easygoing nature makes him a great match for many households — including first-time giant breed owners who are ready to commit to puppy training and continued social development. If you’re looking for a sweet, playful companion who will grow up by your side and fill your home with love (and a few happy zoomies), Sven may be your perfect match. Come meet this special boy and watch him steal your heart! Until the profile is removed from the public’s view, this dog is considered available for adoption.

Hi, I’m Lani and I’m ready to find my forever home. Dog’s Name: Lani Location: Lake In The Hills, IL Date of Birth: 6/1/2021 Gender: Female Breed: Great Dane Color: Tan Point Merle Dog's Weight: 117 Gets along with: Dogs?: All dogs, but needs slow introduction. Cats?: Yes Kids?: Yes Training: Leash trained: Walks loose on leash Crate/Kennel:  Goes into crate/kennel on command Potty trained: Indicates a need to potty and doesn’t have indoor accidents Car:  Rides Well in car Meet Lani Lani has the sweetest soul and has truly blossomed in her foster home. She’s come out of her shell and is now showing her silly, playful personality, complete with happy moments that make you smile every day. Lani is eager to please her people and forms deep, meaningful bonds with those she trusts. She’s still adjusting to free-roaming in a home, and some everyday things — like the dishwasher or a long hallway — can catch her off guard. But with each day, her confidence grows, and she continues to amaze everyone with how far she’s come. Slow and steady is Lani’s way, and she’s absolutely thriving. Lani’s forever family will be patient, gentle, and understanding, knowing that the best things take time. In return, she gives the most beautiful reward: unconditional love. She would do well as the only dog or with a calm male dog companion. Lani is also great with kids and enjoys being part of a loving family. She can comfortably handle a full workday in her crate — and she loves it! A crate is a must for her comfort and security (she’ll need a big one — 54” please!). Lani may still be building confidence, but in the right home, she will continue to shine and become the devoted companion she’s meant to be.
