Story
Neo is about 4 years old and is a Mastiff mix. I’ve had him since he was 2 months old after a friend’s dogs had an unexpected litter, and he has been raised in a loving home his entire life. Neo is a big, sweet boy who loves being close to his person. He can be skittish around new people and situations and needs a little time to warm up, but once he feels comfortable, he is incredibly affectionate and loyal. He loves relaxing around the house, being near his people, and sleeping in bed with me every night. Neo is completely house trained and has completed several weeks of professional training. He is extremely strong and still pulls on the leash, so he needs someone capable of handling a large dog. His ideal home would be with someone patient who will give him time to adjust and build trust. Neo is up to date on vaccinations, receives Simparica Trio monthly, has yearly veterinary checkups, has no special medical needs, and is not neutered. He is the sweetest boy you'll ever meet.

Story
Hello there, I'm Mark! I may be young, but I've got a heart full of love to give. Every morning, I wake up excited for the day ahead. I love playing with my favorite chew toy, but what I really crave is a good game of fetch with a human friend. I'm a quick learner, too! I've already mastered 'sit' and 'stay', and I'm eager to learn more. I promise to be your loyal companion, always ready for an adventure or a cozy nap on the couch. I'm not just looking for a home, I'm looking for a family. Adopt me and let's create a lifetime of wonderful memories together.

Story
Meet Tootsie Roll! This 5-year old English Mastiff Mix is a loyal and devoted gentle giant who came to us after her owner could no longer care for her and is ready to bond hard with her people. Her fun-loving personality is chewy-yet-soft…Tootsie-Pootsie is just a super sweet gal who loves affection and attention and isn’t afraid to show it! With the most loving demeanor around, she will stare into your soul with her incredibly human-like eyes and instantly melt your heart. She is known to sit in front of you and lean allllll her weight into your legs as her version of a hug and sometimes forgets she isn’t lap sized. She will lovingly follow you everywhere, even the bathroom, and will proudly show her love every chance she gets!  At a whopping 100 lbs, Tootsie is just a tad bigger than a candy treat. Majestic and big-boned? Yes! But a mellow gal at heart who has mastered couch napping as if it’s an Olympic sport. And though she appreciates being outside and romping around, committing to short spurts or leisurely strolls is more her speed. Sure…Toots lives in a bigger body but is scared of an ironing board on its side and can easily be contained in a room by putting one down to block off a door opening, even though she could walk right over it. She absolutely loves car rides, belly rubs, toys, gobbling up treats, and sniffing to her hearts content inside and outside! She loves fruit and will enthusiastically eat raspberries right off the bush. She is uber housetrained and has been trained to poop in the woods like a lady. Oh, and you must enthusiastically love slobber, because with those jowls, it’s naturally expected.  Tootsy-Wootsy has a classically beautiful chocolate-colored brindle coat, and one adorable and iconic snaggletooth constantly protruding from her adorable underbite. She currently lives with a 25 lb mini doodle and is really appropriate with playtime and snuggle time despite their obvious size discrepancy (cats unknown). Due to sheer size and lack of history, older or no kids would be best for this smooth and sweet Tootie Pop. Tootsie Roll’s top 3 priorities: 1. A family who is excited to LOVE! Tootsie craves physical touch, affection, and engagement with her humans.  2. A family who wants to be LOVED! This darling girl isn’t afraid to show her adoration, and sloppy kisses are definitely part of the deal. 3. A family with large breed experience. Tootsie is Chihuahua-sized at heart, but owning an XL dog means extra cost for just about everything such as food, equipment, and preventatives, and can amplify the consequences of every single action (i.e. jumping or clearing a room with one “toot”, which quite honestly only happens on occasion).August 11, 2026, 12:03 am

Story
Meet Fred! This big lug is a perfect gentleman. He sits nicely and listens very intently to anything you have to say. Fred is just looking to find someone he can sit with, and maybe give him some pets. He is very gentle and takes treats very nicely. He will carry around a toy for a bit, but he will quickly come back to ask for more affection. His big body is teeming with love and he would really like to share that with someone special. Could that be you?
