Story

Meet Maxwell! Say hello to Maxwell — a big, goofy, loveable and absolutely charming boy who found himself in need of rescue through absolutely no fault of his own. Maxwell was surrendered by his previous family and although his heart is still healing from that loss this incredibly sweet and playful boy is ready to find the safe, loving and forever home he so deeply deserves. Maxwell's Story: Maxwell came to us when his previous family could no longer keep him — a situation that was completely out of his control and not a reflection of who he is in any way whatsoever. His former family described him as a big, goofy and immensely playful companion who brought joy and laughter into their home every single day. That dog is still very much in there — working through the confusion of losing everything familiar and slowly but surely letting his wonderful personality shine through again. What His Previous Family Said About Him: The people who knew Maxwell best described him as: Big, Goofy, Gentle, Affectionate — Maxwell has a larger than life personality and a silly, playful nature that is completely and utterly endearing Immensely Playful — This boy loves to play and brings so much fun and energy to every interaction Perfectly House Trained — Maxwell is fully house broken and knows exactly how to behave in a home environment Crate Trained — Maxwell is comfortable and relaxed in his crate and uses it without any issues whatsoever Free Roams Peacefully — When left alone Maxwell is capable of free roaming the home without any adverse incidents. A truly remarkable quality that speaks to his calm and trustworthy nature History with Children & Dogs — Maxwell has previously lived successfully with both children and dogs of all sizes showing his adaptable and gentle nature. He's currently living with other dogs at his foster home and has been very friendly with them. What Maxwell Needs: A Calm & Quiet Home — Maxwell is a sensitive boy who truly thrives in a peaceful environment where he can feel completely safe and secure Calm Canine Companions — Maxwell does beautifully in playgroups and enjoys the company of other dogs. He does best with calmer dogs as high energy canines can sometimes feel overwhelming for this gentle soul ‍‍ Child Free Environment Recommended — Although Maxwell has a positive history with children his tendency to be a little jumpy and nervous around new people means he would do best and feel most comfortable in a home without young children Patience & Understanding — Maxwell may be cautious when meeting new people at first but given time, gentleness and consistency this boy will reward you with a loyalty and love that is truly beyond measure A Note About Maxwell: Maxwell did not choose this situation. He did not do anything wrong. He is simply a big hearted, goofy and loving boy who lost his family and is trying his very best to navigate a world that suddenly feels very uncertain and scary. A loyal, playful, sweet and absolutely wonderful companion who has so much love left to give and is desperately hoping someone will give him the chance to give it. Maxwell is longing for a safe, quiet and loving forever home where he can finally exhale, be himself completely and spend every single day being the goofy and devoted companion he was always meant to be. He has already been through so much. It is time for Maxwell's story to have the happy ending he so truly deserves. Could you be the one to give it to him?

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!

Story

Roscoe (A567045) is a 7-year-old senior with the sweetest, most gentle soul. He has a calm, quiet demeanor and seems very well-mannered. As soon as we got outside, he went potty right away — twice — which is often a good sign that he may already be housebroken and had likely been holding it.Roscoe walks nicely on leash and only pulls a little when something especially interesting catches his nose… like a pine tree (his personal favorite). Otherwise, he’s happy to stroll along at your side.He sits politely, takes treats with the gentlest mouth, and has the kind of soulful, sad eyes that make you wonder how such a sweet dog ended up in a shelter at all.Roscoe is the kind of dog who just wants a little kindness and a soft place to land. If you come meet him, remember he loves baby talk and scratches behind his ears — it’s the fastest way to make a new best friend.https://www.instagram.com/reels/DVzvQcRDfFl/https://www.facebook.com/reel/1995385857856753/?mibextid=wwXIfr&rdid=GR5R6zHk1q5UQf3r#
