Hi, I'm Bear, a striking 3-year-old black and white Mastiff mix who's ready to steal your heart! 🐾 I'm a big guy at 88 pounds with an even bigger personality—affectionate, loyal, and playful, with smarts to match. I'm already neutered and housetrained, so I'm set up for success in my forever home, and I do wonderfully with kids. I'd thrive best as your one and only pup (no other dogs or cats for me), but in a loving family like that, I'll be your devoted companion. My adoption fee is free, so come meet this cuddly giant and let's start our adventure together! 💕Apply on havenandheartrescue.org

Story
Hi, I’m King and I’m ready to find my forever home! Dog’s Name: KingLocation: Elmhurst, ILAge: 4 yearsGender: MaleWeight: Approximately 83 lbsNeutered: Yes Gets along with:Dogs?: Yes! King has done well with both big and small dogs. During his dog introduction, he wasn't reactive at all—in fact, he barely seemed concerned that the other dogs were there. He simply found himself a dog bed, laid down, and went to sleep. Cats?: UnknownKids?: Unknown. His foster home does not have children. Training:Leash Trained: Working on it! King is still learning not to pull on leash.Crate Trained: Yes! King likes his crate, especially when his blanket is inside, and willingly goes into it.Potty Trained: Yes! King has had ZERO accidents in his foster home. Car: Rides well in the car. He jumps in all by himself, settles down nicely, and enjoys looking out the windows.Commands: King sits before being fed, comes when called, and gives paw. Meet King — The Chill Guy Who Goes With the Flow If your ideal giant dog is less “LET'S DO ALL THE THINGS!” and more “Sure, I'm good with whatever,” we may have found your guy. King is one seriously chill dude. At 4 years old and approximately 83 pounds, King is past the crazy puppy stage and has settled beautifully into his foster home. He's decompressed, comfortable, and officially ready to find his forever family. His foster describes him as a “goes with the flow kinda dog,” and honestly, King seems determined to prove it. One of the best examples happened during his introduction to his foster family's dogs. New dogs? New situation? Lots going on? King couldn't have cared less. He wasn't reactive at all. He acknowledged the situation, found himself a comfy dog bed and fell asleep. Apparently King had more important things on his schedule. Like napping. Speaking of which, King is something of a dog-bed connoisseur. He enjoys sleeping on all the dog beds in the house. Why commit to one when you can rotate through the entire collection? King is also wonderfully affectionate in his own easygoing way. He loves his treats and takes them very gently, which is especially sweet coming from a big guy. And he's already got quite a few household manners checked off his résumé. King is completely potty trained and hasn't had a single accident in his foster home. He willingly goes into his crate and enjoys relaxing there with his blanket. He sits before he's fed, comes when called, and will even give you his paw. He's still working on not pulling during leash walks, but he's already showing that he's perfectly capable of learning. And when it's time to hit the road? King is ready. He jumps into the car by himself, settles down for the ride, and enjoys watching the world go by through the windows. One of King's biggest selling points may be just how easygoing and adaptable he seems to be. He's friendly with dogs both big and small.He's potty trained.He's comfortable in his crate.He rides nicely in the car.He already knows several basic commands.He takes treats gently.And he's apparently never met a dog bed he didn't like. Even better, King's foster believes he could be a wonderful choice for someone new to giant breeds. A fenced yard would certainly be a bonus, but more than anything, King seems to need a family willing to give this laid-back guy a place to belong. He's not asking to be the center of attention every second. Just give him some treats, a cozy blanket, a few strategically placed dog beds, and people to call his own. King is ready for his next chapter. And considering how well he goes with the flow, we have a feeling he'll be pretty happy as long as that next chapter includes you. Could King be the easygoing giant your family has been waiting for? Until the profile is removed from the public’s view, this dog is considered available for adoption.

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.

Hi, I’m Autumn  and I’m ready to find my forever home!  Dog’s Name: Autumn Location: Plano, IL Date of Birth: 6/13/2026 Gender: Female  Breed: Daniff Color: Brindle Gets along with: Dogs?: All dogs Cats?:  Unknown, but likley due to age Kids?: All kids Training: Leash Trained: Walks loose leash Crate Trained: Goes to crate/kennel on command Potty Trained: Indicates a need to potty and doesn’t have indoor accidents Car:  Rides well in car Meet Autumn Autumn is a growing girl with an even bigger personality. This happy-go-lucky puppy believes everyone she meets is her new best friend, and she's always ready to spread a little joy wherever she goes. Whether she's romping around the yard with her canine friends, exploring her surroundings, or proudly pulling every single toy out of the toy bin, Autumn knows how to make everyday life an adventure. Like most puppies, Autumn has two speeds: full-speed fun and completely exhausted! She loves a good play session and has plenty of that adorable puppy energy, but once she's worn herself out, she's more than happy to curl up on the couch for some cuddles or settle in for a long, well-deserved nap. She's the perfect combination of silly, sweet, and snuggly. Autumn is already making wonderful progress with her training. She's potty trained and does well in her crate once she understands it's time to settle down. She's also learning basic commands, and her love of food and treats makes her an enthusiastic student! She's a smart little girl who catches on quickly, especially when there's a tasty reward involved. Of course, Autumn is still very much a puppy, and with that comes a little mischief! She's still learning the difference between her toys and everyday household items, but she responds well to correction and happily moves on to something more appropriate. Her future family should be prepared to continue teaching her good manners, providing structure, and helping her grow into a well-behaved giant. Autumn has done wonderfully with other dogs and children, making her a promising addition to many types of families. She hasn't been tested with cats yet, but given her young age, she may be able to learn to live peacefully with feline friends through patient, supervised introductions. As a Dane/Mastiff mix, Autumn has plenty of growing left to do, and her future family should be ready for all the joys and responsibilities that come with raising a giant breed puppy. She'll need continued training, socialization, patience, and plenty of opportunities to play, learn, and explore. Autumn is looking for a family that will embrace her goofy puppy antics, celebrate her progress, and give her the love and guidance she needs to become the amazing adult dog she's destined to be. In return, she promises endless entertainment, enthusiastic greetings, plenty of cuddles, and a lifetime of unconditional love. If you're looking for a sweet, playful, affectionate puppy who will grow right alongside your family, Autumn might just be your perfect match!
