Story

https://foha.org/pet/queen2023/ All hail me, your Queen! Hey there! My name is Queen, and I am a big, beautiful pup with a larger-than-life personality and a royal charm. The great outdoors is where I truly shine—I absolutely love going for walks and can never get enough of them! Leash walking? Piece of cake! I’m always ready for an adventure. Hiking is one of my absolute favorite things to do. Whether it’s a winding trail through the woods or a peaceful park, I’m in my element. There’s just something magical about exploring nature—splashing my paws in streams, sniffing out all the new scents, and, of course, rolling in the grass (I just have to!). I’m also a fantastic travel buddy. Car rides? No problem! I’m happy to either gaze out the window, watching the world go by, or just settle in with a tasty treat. And speaking of treats… let’s talk food. I. Am. FOOD. DRIVEN. Seriously, if you’ve got snacks, you have my full attention. Training? Yep, I’ve had training sessions, and with the right motivation (ahem, treats), I’m eager to learn and show off my skills. But let’s be real—I like to think I’m the one in charge, so I need a patient and consistent owner who knows my breed and can keep me on the right track. I’ve been in the shelter for two whole years, just waiting for my perfect match. I may come off as a bit sensitive, so I’d thrive in a quiet home where I can feel safe and comfortable. But once I warm up to you? Oh boy, get ready for endless love, constant demands for attention, and yes—plenty of slobbery kisses! If you can handle that, I promise I’ll be your best girl. I’d do best as the only dog in the home, soaking up all the love and attention (because let’s face it, I deserve it!). A household without kids would also be ideal, given my size and my big, excitable heart. But don’t let my size fool you—I’m a total teddy bear and a great house guest. I love hanging out with my favorite people, cuddling up, and just being part of the family. If you’re looking for a majestic, affectionate, food-loving, adventure-ready companion, I’m your girl! Let’s take on the world, one walk (or treat) at a time. If you’d like to meet me, fill out an application (no obligation), and let’s make it happen. Hope to see you soon!

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?

***50% of Piper's adoption fee is sponsored by Petfinder*** fam, what is up? i am piper, legitimately the coolest and nicest dog in town but actually … i am literally THAT guy. i’m pretty easy going, good in the car, and on the couch. that new netflix show that’s def gonna be coming out about the karen dever case? i will watch it with you. fr. even if you’re already following it on tiktok. i’ll listen to you talk about it AND i will watch the entire show with you and still act cool with it. so you know…if you’re like interested or whadeva, tap my line and let’s be besties for the resties 🫶🏼 ciao, piper What the people have to say about me: Meet this handsome, laidback boy who's ready to steal your heart! Piper is a true gentle giant, content to lounge and cuddle or play with his favorite toys. He's a go anywhere kinda guy (brewery/patio approved!) and he's got a smile that will melt your heart! Piper is a loving boy who has shown himself to be a truly medium energy fella - a couple of average walks, some playtime, and something to engage his brain and he's good to go! Piper is also quite the paradox - on one hand he is so smart and eager to please! He knows sit and paw, seems to know to lie down and even comes back when called. On the other hand, this poor guy couldn't figure out how a kong works! It's okay Piper, we get it. You're book smart and might just lack some commonsense! Piper loves to chew and is an expert at defluffing a good stuffed toy. He loves his playtime with his doggy pals equally to his cuddles with his human companions. Swiper says there's no such thing as being too big to be a lapdog and he's always ready to melt into you and offer his belly for some rubs! With his sweet disposition and easygoing nature, he's looking for a loving home where he can be your best friend and a cherished member of the family. Piper is learning that sharing is caring and is readily trainable. He has a chill demeanor and is a joy to be around! Piper's got a heart as big as his head and is just waiting to adore his forever family with!

Story

*Woof* Meet me any time from 12pm to 7pm at 71 Oglethorpe St NW!ICYDK, `Bark Hamill` was the name of the dog of actor Mark Hamill, who played Luke Skywalker in the Star Wars franchise. Yes, I know, that dog looked a tiny bit different (small and white), but I am still pretty honored to be named after a pup that had such a famous dad!I am the goodest boy, as at least 6 people here will confirm, and well-suited to be your new loyal companion. I love my daily walks and with me, you don`t need to have athletic ambitions and run for long stretches, but I am always up for a well-paced walk with decent sniff breaks. I like this to be followed by a good snooze, please.I know some of the basic things, like sit, and am a good leash-walker, so we should be off to a good start when you take me home. Otherwise, I am a laid-back, easygoing pup who is always happy to be around his people. In sum, I am perfect -- and so ready to make your life perfect, too!

Story

Hello! This is Kori. She is 5 yrs old. An sweet energetic girl. She loves people and is also very affectionate. Kori came to me as a boarding and daycare client however her previous owners went through some life changes and couldnt keep her. They were considering giving her to the shelter however I didn't think she would do well in that environment. She does get nervous in new noisy places so i decided to foster. I run a boarding business so shes been around all size dogs. She does well with male dogs. Other females take some warming up to but in time she's ready to play. She has been around small children via her previous home and loves children. She does know the basics (Sit, Stay, Down etc.) She is house and crate trained as well. She is an free adoption. She is coming with everything needed (Beds, Crate, food). I am also offering to help pay 50% towards training to help her transition into her new home. Kori is such a good dog. She would make a great addition to the family.

Here’s our super cute litter of 4. They and their mom were found in a ditch next to a school. Their mom weighs 70 pounds. She is not vetted yet, so we will only be taking the puppies for now.
