Story
https://foha.org/pet/queen2023/ All hail me, your Queen! Hey there! My name is Queen, and I am a big, beautiful pup with a larger-than-life personality and a royal charm. The great outdoors is where I truly shine—I absolutely love going for walks and can never get enough of them! Leash walking? Piece of cake! I’m always ready for an adventure. Hiking is one of my absolute favorite things to do. Whether it’s a winding trail through the woods or a peaceful park, I’m in my element. There’s just something magical about exploring nature—splashing my paws in streams, sniffing out all the new scents, and, of course, rolling in the grass (I just have to!). I’m also a fantastic travel buddy. Car rides? No problem! I’m happy to either gaze out the window, watching the world go by, or just settle in with a tasty treat. And speaking of treats… let’s talk food. I. Am. FOOD. DRIVEN. Seriously, if you’ve got snacks, you have my full attention. Training? Yep, I’ve had training sessions, and with the right motivation (ahem, treats), I’m eager to learn and show off my skills. But let’s be real—I like to think I’m the one in charge, so I need a patient and consistent owner who knows my breed and can keep me on the right track. I’ve been in the shelter for two whole years, just waiting for my perfect match. I may come off as a bit sensitive, so I’d thrive in a quiet home where I can feel safe and comfortable. But once I warm up to you? Oh boy, get ready for endless love, constant demands for attention, and yes—plenty of slobbery kisses! If you can handle that, I promise I’ll be your best girl. I’d do best as the only dog in the home, soaking up all the love and attention (because let’s face it, I deserve it!). A household without kids would also be ideal, given my size and my big, excitable heart. But don’t let my size fool you—I’m a total teddy bear and a great house guest. I love hanging out with my favorite people, cuddling up, and just being part of the family. If you’re looking for a majestic, affectionate, food-loving, adventure-ready companion, I’m your girl! Let’s take on the world, one walk (or treat) at a time. If you’d like to meet me, fill out an application (no obligation), and let’s make it happen. Hope to see you soon!

Story
*Woof* I`m in a foster home. To meet me reach out to my foster caregiver at faithsanders25@gmail.com.Onyx is an 80lb cuddle bug who loves to play but can also appreciate a good nap. He loves to meet new people regardless of age, as long as they agree to never stop petting him. He is crate trained and potty trained and would make a fantastic companion for a single person or even a family with children. Onyx is a curious big guy always up for a long walk through the neighborhood. He is currently working on loose leash walking but responds well to positive reinforcement and is extremely food motivated. He knows basic commands such as sit, stay, down, and leave it but is eager and willing to learn more. If you are looking for a gentle giant to join your family, Onyx may be the one for you!
