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#

Story
Sampson has currently been staying with us over at Big Dog Run and let me tell you we have fallen in LOVE??. Sampson is as big of a gentle giant as one can get. With his calm demeanor and loving personality Sampson makes for the perfect 100lb lap dog??. When you approach his kennels he will greet you with the biggest smile on his face and a little wiggle dance????. Sampson has been socialized around a plethora of dogs over at Big Dog Run and has done phenomenal with all dogs of different sizes and energy types. Sampson hasn’t met a person or dog he does not love??.Sampson loves to be around his people but also does very well being independent and left alone. Sampson is currently working on some leash manners and is doing very so very well! Sampson is a mild to low energy dog that would do well with only a couple walks a day (and maybe 20 minutes of his favorite game.. FETCH??) and grazing into your eyes in complete admiration for the rest????. Overall Sampson is as perfect as perfect gets!! This boy would do well in many different household types!Interested in me email Fosterpgcpets@co.pg.md.us

Story
Meet Deuce! A573603 Deuce is a 1-year-old, 70 lb German Shepherd/Mastiff mix who has been waiting at the shelter since 8/25, after being brought in as a stray. Deuce is just a big, goofy, playful puppy with a healthy bit of young-boy energy! He’s friendly, social, and clearly wants to engage with the world around him. He loves people, although he’s not the type of dog who needs to be glued to your side or sitting in your lap. He seems very interested in treats, too! He’s a handsome young guy with the cutest floppy ears, the most expressive eyes, although he could stand to gain a few pounds.Right now, Deuce is wearing a cone while a small skin wound in his undercarriage area heals.Deuce also seemed very interested in meeting other dogs, although he has not yet had a formal dog-to-dog evaluation. As always, slow introductions after appropriate decompression is recommended. But what has impressed us most about Deuce is how wonderful he has been with children .I’ve personally witnessed two different interactions between Deuce and children under 8, and they showed two different sides of this sweet boy. When one child wanted to play, Deuce was enthusiastic, playful, and friendly. With another little girl, he simply stood calmly beside her while she gently petted him. No jumping all over her, no overwhelming her — just a big dog happily enjoying the attention. For a young, energetic dog who is currently stuck in a stressful shelter environment with very little opportunity to burn off that puppy energy, Deuce is showing some really promising qualities. He has the friendliness, playfulness, and gentleness that could make him an amazing family dog with the right home, structure, exercise, and continued training.Deuce deserves the chance to grow up outside of a kennel and show someone just how special he can be. https://www.instagram.com/reels/DdmKoocsywv/? Please note: The shelter can be a stressful and scary place, and a dog’s behavior here may not fully reflect how they’ll blossom once they feel safe and decompressed at home.Deuce is available for adoption or foster at: Prince George’s County Animal Services3750 Brown Station RdUpper Marlboro, MD 20772
