Story
You can fill out an adoption application online on our official website.All of the animals posted on our site have been temperament tested. While not all are in the immediate area, once we have processed and approved your application, we will move the dog to our adoptive area for you to meet, greet and hopefully adopt. Sometimes we will have more than one application on a dog. That does not mean it automatically goes to another family but you should be aware of the fact that until you are approved and set up for the meet/greet.. the dog could get adopted by another applicant.Hello to all of my fellow Mastiff lovers.   I would like to introduce myself.  My name is Bear and I am the quintessential Mastiff mix of loyalty, playfulness, gentleness, and protectiveness.  I would love to share my home with a human/s who know my breed well, as I am not a novice owner.  I take my job seriously and want you to know when there is a shift in the environment that may need your attention.   I am not a big barker but I am vigilant until you tell me that everything is ok.     I enjoy my crate and it can be a place of calm if I start to take my job too seriously.  I am completely house trained as well.     My strengths:  Smart - I know my 8 basic safety commands in varying capacities - Look, Touch, Sit, Down Stay, Come, Leave it, and Place.  Playful - I love toys, running, jumping, and hanging with my people.  Polite - I am polite on leash unless something fun comes my way like chickens or dogs.   I can become cautious if I see strangers but I move along fine if you tell me everything's ok.   Quiet - I am not a big barker and would prefer watching as things come and go in my environment.  Loyal - I am the most trustworthy guy you will ever know once I know that you are a part of my pack.  I am trusting and enjoy a cuddle once in a while.  I will look for you and want to be with you always.  Trusting - Once you belong to me, I am yours forever.   I am a great sleeper and love my meals.  I enjoy riding in cars.   I enjoy long walks when the weather is not too hot.  I think I would enjoy hiking a lot.     Things I am working on:  Commands - Perfecting my 8 safety commands.  Trusting new things - The more places I go and the more you can let me watch from a distance, the more I can trust new places.  Trusting new people - I need slow introductions with new people who are confident and want to have a relationship.  I am not interested in casual interactions.  I will do best if I know what you expect of me in these situations but I would prefer not to be pushed or 'talked into' socializing.     I will do better with no children or other pets in the home, as I have a hard time sharing the affection.  I was not proofed with cats so I don't know how I feel about them.     General Mastiff traits -  Mastiffs are known for their gentle, calm, and loyal personalities, making them excellent family pets. They are also protective and courageous, exhibiting a natural instinct to guard their families and homes. Despite their imposing size, Mastiffs are often described as 'gentle giants' due to their affectionate and patient nature.    Here's a more detailed look at their personality traits: Loyal and Devoted: Mastiffs form strong bonds with their families and are known for their unwavering loyalty.    Gentle and Affectionate: They are naturally gentle and affectionate, especially with their family members, and enjoy cuddling and close companionship.    Calm and Patient: Mastiffs are generally calm and patient, making them suitable for households with children and other pets, though early socialization and training are still important.    Protective and Courageous: They possess a natural instinct to protect their families and territory, making them excellent watchdogs.    Intelligent and Eager to Please: Mastiffs are intelligent dogs that learn quickly and respond well to positive reinforcement training methods.    Relatively Quiet: While they can be alert and watchful, they are not typically known for excessive barking.    Can be Suspicious of Strangers: It's common for Mastiffs to be wary of strangers, but with proper socialization, they can learn to be more accepting.    If you are interested in Bear, please fill out an application at: https://reachoutrescue.rescuegroups.org/forms/form?formid=4588    Or contact: rorrcanine@gmail.com   *** Click here to sponsor this dog! ***Visit this organization's web site to see any additional information available about this pet.December 6, 2025, 10:18 pm

Story
Current Location: Ijamsville, MD Meet Our Resident Gentle Giant: Freya! If you’ve been looking for a 105lb shadow who has absolutely no concept of personal space, look no further. This stunning brindle Mastiff is a masterpiece of muscles and mush! The Personality: She is a "sweet and happy" soul who treats every human she meets like a long-lost best friend. While she might look imposing, she’s actually convinced she is a tiny, 10lb lap dog. If you sit down, expect a century of pure love to land right in your lap! The "Bull in a China Shop": Life with her is never boring. She navigates the world with maximum enthusiasm and minimum coordination. Whether it's a "happy helicopter" tail or a clumsy zoomie session, she’s a lovable wrecking ball who just wants to be where the action is. Social Status: Dog Friendly - She’s a social butterfly! She gets along great with other canine companions and loves a good play session. Human Obsessed - Her favorite place on earth is wherever you are (specifically, on top of your feet or in your lap). Appearance - A gorgeous, striking brindle coat that is as soft as her heart. Fun Fact: She hasn't quite figured out that she's outgrown your lap, but she’s more than happy to keep trying until she fits! Are you the lap she's been waiting for? If so please click “apply for adoption” or submit an application through the Adopt tab.

Story
Hi, I’m Luke, and I’m a big, lovable boy tipping the scales at just over 100 lbs! Don’t let my size fool you—I’m a happy, easygoing pup who just wants to play, explore, and cuddle. I’m all about the good things in life: squeaky toys, water play, long walks, and best of all—snuggle time on the couch. I’m a pro at giving hugs (though I’m working on not jumping up too hard to give them—oops!). I get along great with other dogs and kids, but because of my size and enthusiasm, I’d do best with older children who won’t get accidentally knocked over during playtime. I’m crate trained, housebroken, and walk nicely on a leash—unless there’s a squirrel… then it’s game on! I do have a slight prey drive, so a little guidance goes a long way. If you’re looking for a big-hearted, playful companion to fill your home with love (and maybe take up some space on your couch), I’m your guy. Let’s make forever happen! 🐾 Local adoption fee is $200(in TX) Out of state adoption fee is $450 (includes transport to your area)
