Story

Meet Our Sweet Brindle Girl, Dexi! This adorable 9-month-old brindle mastiff mix puppy with the cutest floppy ears is pure love wrapped in fur! She has the sweetest personality and is happiest when she’s surrounded by people or playing with other dogs. She absolutely loves everyone she meets and gets along wonderfully with other pups, making her a perfect addition to a home with furry siblings. When she’s not making new friends, you’ll find her happily playing with her toys, enjoying a good meal, or snuggling with her foster family. She’s currently living with her two dog foster siblings, and she loves them so much! They’ve helped show her how fun life can be, and she’s ready to bring that same joy to her very own forever family. All of our dogs are spayed or neutered, up to date on age appropriate vaccinations, microchipped and if over 6 months of age, heartworm tested and on heartworm preventative in their foster home. We require an approved application to meet any of our dogs. We do not have a shelter location and will not arrange a meeting without an approved application. We strive to make sure the bios provided for our dogs are complete and accurate; we do understand that mistakes happen, however, so if you absolutely cannot find the answer to your question in the dog's bio, you can contact us for more information. We require a home visit for each dog we adopt out, so we adopt within a 2 hour radius of Dayton, OH. If you are outside of this radius, we encourage you to contact your local rescue or shelter.

Story

Aizen is one of 12 puppies born a year ago, (19 Jan 2025). We have adopted out some of his brothers and sisters. He is a big ball of fun and has a great personality and is a stocky boy like his dad. We still have his father (sire) living with me and his mother (dam) lives with my son. We still have four (4) others we are adopting as you will see on the website. Aizen is one year old, and he needs a good home soon. He is kennel trained and house trained. We originally tried to sell the puppies to recoup the high Vet bills but now we are just concerned that he gets a great, safe home. All puppy shots and vet visits are up to date with available documentation. The annual rabies shot is due soon. He is actually called, Doge de Bordeaux or French Mastiff. They are ACA registered. Heatly, active, loveable and fun to be around which make a great companion.

Story

Ralph the Derp! Ralph is a huge friendly, enthusiastic, uncoordinated 4-legged energetic goofball! He was rescued from “death row” at a high kill shelter, as a skinny stray with a treatable skin condition. His fur has almost completely grown in & he is now at a healthy weight. This overgrown mastiff/Cane Corso mix pup has no comprehension of his size, leaning into humans for affection or trying to ooze onto laps for cuddles. He is being trained not to jump and not to paw for attention/affection/play because he currently has 85# of mass behind those “congenial” moves. Ralph plays well with dogs of all sizes, but would do best with med-to-larger dogs due to his size & poorly curbed gusto. He hordes toys, taking them all to his chosen dog bed of the day. He likes to carry a special toy “baby” in his mouth when going out in the yard. He does need to be fed in his crate & will guard his empty food bowl from other dogs, unless he is distracted with a toy & led outdoors after meals. He is great on a leash, makes awesome grunty sounds when cuddled, enjoys baths. Ralph will make a great addition to an active family with older children. He is eager to please, food and affection oriented (although a bit stubborn at times), making him an ideal candidate for success with continuation of his training. Please consider adopting the gorgeous big derp into your home. Attributes: In training to avoid jumping/pawing Active family He is neutered, microchipped, had recent cherry eye repair and up to date on all vaccines and preventions. Local adoption fee is $200(in TX) Out of state adoption fee is $450 (includes transport to your area)

Story

Hi, I’m Luke, and I’m a big, lovable boy tipping the scales at just over 100 lbs! Don’t let my size fool you—I’m a happy, easygoing pup who just wants to play, explore, and cuddle. I’m all about the good things in life: squeaky toys, water play, long walks, and best of all—snuggle time on the couch. I’m a pro at giving hugs (though I’m working on not jumping up too hard to give them—oops!). I get along great with other dogs and kids, but because of my size and enthusiasm, I’d do best with older children who won’t get accidentally knocked over during playtime. I’m crate trained, housebroken, and walk nicely on a leash—unless there’s a squirrel… then it’s game on! I do have a slight prey drive, so a little guidance goes a long way. If you’re looking for a big-hearted, playful companion to fill your home with love (and maybe take up some space on your couch), I’m your guy. Let’s make forever happen! 🐾 Local adoption fee is $200(in TX) Out of state adoption fee is $450 (includes transport to your area)

Story

Finn may look like a rockstar with his striking Mastiff–Shepherd good looks, but at heart, he’s a big, soft lovebug. Weighing in at about 60 pounds, Finn has grown into a handsome boy with a beautiful gray and tan coat, soulful eyes, and an even bigger personality. Despite his star-quality appearance, Finn is more of a laid-back, easygoing guy—think Eeyore vibes, but with engines revved and ready to love. From the moment he wakes up, he’s prepared to shower his people with affection… and trust us, it’s A LOT of love! Finn does well with other dogs and does need a slow, proper introductions to new friends—both two-legged and four-legged. Once he knows you, he loves you deeply. He’s happiest when he has a buddy (human or canine) to share his world with. Affection is Finn’s specialty. When someone comes to greet him, he lights up, runs over with enthusiasm, and hands out slobbery kisses and big hugs like they’re backstage passes. His joy is genuine, his heart is huge, and he’s always thrilled to see his people. If you’re looking for a big, lovable, slightly goofy rockstar who will adore you endlessly, Finn is ready to take center stage in your heart. Local adoption only $200 (in TX)
