Story
3 years old (estimated) Neutered male Has done well with another dog at the shelter Looking for a home without cats No known experience with children Has done well with potty training in the shelter Remy is the definition of a gentle giant — a laid-back, lovable boy who’s as sweet as he is big! He’s great on a leash and enjoys going for leisurely walks, and he’s sure to win you over with his slobbery kisses and the adorable bubbles he makes after a good drink of water. He’s done well meeting another dog at the shelter and has shown good potty training habits in his kennel. If you’re looking for a big, easygoing buddy with an even bigger heart, Remy might just be your perfect match! The online adoption listing websites require that we choose a predominant breed or breed mix for our dogs. Visual breed identification in dogs is unreliable so for most of the dogs we are only guessing at predominant breed or breed mix. We encourage you to select your new companion by considering each dog's individual personality and pet qualities instead of relying on a breed label that is only a guess.February 4, 2026, 5:49 pm

Story
Meet Sam! Sam is a very handsome pup, estimated at about 3 years old. He’s thought to be a Mastiff Mix, but, rather small for the breed. Sadly, Sam found himself at an overcrowded noisy animal control facility down south. He deserves a forever home and family of his own, and we want to help him get there!! This precious pup absolutely loves people and is good with older kids who are respectful of dogs. We expect he is good with lower energy dogs. Dogs who are too active might scare him and cause him to react. Sam absolutely loves belly rubs, and treats too! He's a little rough around the edges in terms of training but clearly is eager to learn. Sam is in overall good physical shape however he does have some vision issues causing him to sometimes miss things coming his way….this is why we expect he’d be scared by higher energy dogs, and high-activity youngsters. Sam is neutered, up to date on vaccinations, microchipped, heartworm negative and on preventative. We would still like to get Sam to an eye specialist for a comprehensive examination of his eyes/vision. If you’d like to add Sam to your family, please contact BAARKDogRescue@gmail.com or 847-852-0895.
