Story
Howie. The most real, smart, easy dog of 2025. An absolute asset to any home. He is dog, cat, kid, bird, farm, everything friendly. He is still gaining weight and will be a solid 110lb mastiff. Howise is gentle, easy, 100 percent kennel and house trained and is the same dog every minute of every day. Howie is going to be hard to let go. He will greet you every minute with towels of drool, but it's really love we have learned. Howie would love a family of his own that he can love and care for. Need a shop dog to greet everyone? This is your guy. Need a friend to walk with? He has your back. Howie is one you have to meet and it will all make sense. We will happily keep him to manage the farm and run payroll and would not be sad if he was never adopted and had to stay with us. He is THAT perfect. Apply for Howie today, or don't. Either way.

Story
Hi, I’m Beth and I’m new to the rescue. I am currently decompressing and getting used to my foster family.  This is what they know about me so far.   Dog’s Name: Beth Location: Plano, Il. Date of Birth: 02/14/2021 Gender: Female Breed:  Mastiff Color: Brindle Dog's Weight: 140 Gets along with: Dogs?: All dogs Cats?:  Unknown Kids?: Kids over 8 Training: Leash trained: We're working on it Crate/Kennel:  Goes into crate/kennel on command Potty Trained: Indicates need to potty and doesn't have indoor accidents Car: Rides well in car Has good recall Meet Beth – The Goofy, Gentle Giant! Beth is a stunning brindle Mastiff with a heart as big as her paws!  Beth’s journey to us began after a devastating house fire left her former family without a place where dogs were allowed. Recently having had puppies and surrendered at a shelter, Beth has shown nothing but grace, sweetness, and an eagerness to love. Beth is the definition of a people-pleaser. She adores being petted, leans in for affection, and takes her nap schedule very seriously. At roughly 140 lbs, she doesn’t quite realize her size yet, but she’s learning quickly that sitting next to you is just as good as sitting on you. When she’s excited, she taps her feet in a happy little dance that is sure to win your heart. She is potty trained, crate trained at night, and behaves beautifully when left out—no chewing, no mischief, just naps and gentle curiosity. Beth has no aggression whatsoever and gets along well with other dogs. She enjoys cuddling with toys but won’t destroy them, making her a wonderfully easy companion. Her compatibility with cats is unknown, and due to her size and tendency to lean into affection, she would do best with older children. Beth would be a wonderful match for a first-time giant breed owner—she’s gentle, forgiving, and eager to please. She doesn’t require a fenced yard and would thrive in a home that offers plenty of couch time, cuddles, and companionship. She’ll fit in beautifully as an only dog or as part of a multi-dog household. If you’re looking for a sweet, soothing, oversized best friend who will dance for joy when you walk into the room, Beth may just be the perfect addition to your family.
