Story
Knight is a Covid baby/ adoptee. I got him as the world was shutting down. Due to the COVID shutdown he was trained well past his puppy years. He has basic training and knows commands well but exhibits some stubbornness. As a result of the pandemic he was used to being out & having someone around everyday. When we relocated to a new apt and utilized a crate for him we noticed he exhibited behaviors associated with separation anxiety & would potty in the crate. Although he is fully potty trained he does still exhibit those behaviors when we leave for extended period of time or when he has to go in the crate. He is a very loving dog. Very intelligent very good with kids and cats. He isn’t very socialized with other dogs but has not shown any signs of aggression towards them when encountered just an excitement that can come across as threatening because of his size. He is a great dog, our apt is just not conducive to those accidents anymore. If we could correct this we wouldn’t rehome him

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
