Story
He was left behind when his owners moved out. Very affectionate.He looks like a goofy, kind of floppy hound dog as he ambles around. He’s sweet and affectionate. Gets along with most dogs. He’s a little bossy with food especially with a timid dog. Feeding in a crate solves that. Loves his play time in the yard with two stout dogs. Great on a leash. The Adoption Fee Includes Age-Appropriate Vaccinations (DA2PPV, Bordetella, Rabies), Deworming, Spay/Neuter, Microchip, Flea, Tick and Heartworm Treatment and Prevention, and Sheltering. Adult Dogs are Heartworm Tested and Treated as Needed. Tanner's adoption fee (if picked up locally in Crossville, Tennessee) is $225. If transport is needed, his adoption fee is $525 (out of state, East Coast, Great Lakes or New England regions).Thank You for Your Interest in Adopting a Canine Companion from Foccas-tn.org!To Apply Please Copy and Paste to Your Browser:https://service.sheltermanager.com/asmservice?account=hb2428&method=online_form_html&formid=41LOCATED IN CROSSVILLE, CUMBERLAND COUNTY, TN.

Story
Name: Shaq Sex: Male Estimated Age: About a year old Best Guess for Breed: Mixed Breed Mastiff Dog Weight: About 60 lbs Lives With: Dogs and adults (including kids). Housebroken? Shaq is housebroken. He is currently working on crate training (making great progress!) and learning his basic commands. Story: Shaq was rescued from a shelter locally in Washington, DC. Shaq is a happy sweetie who loves people and gets along great with other dogs and puppies. He knows just how to get comfortable up on the couch with his humans, and will love to join you on walks and trots around the neighborhood. Shaq is just looking for someone to be his new best furend and we know that he will repay them with endless amounts of love and tail wags. As a puppy, Shaq will need an adopter who is committed to setting him up for success by enrolling in obedience training and exercising him both mentally and physically. He will also need love, patience, and socialization in order to thrive! What my foster says: Shaq is really just the best, and we absolutely adore him. He is 100% the most cuddly dog we have fostered and is an absolute ham. He’s great with other dogs and all humans. He’s fully potty trained and only goes to the bathroom outside. He’s good on the leash, but can be a little mouthy when he plays (like a typical puppy) - we are working with him to correct this behavior and he’s responding really well to training. He has lived with kids and other dogs and does great. He’s a great, happy boy and will make a fabulous family dog or companion! The fee to adopt Shaq is $475. That covers the cost of all his vaccines, the collar he’s wearing, his transport to DC and his care in his foster home. He’s up to date on all age appropriate vaccines and neutered. Shaq has been seen by a shelter vet and we are not aware of any health issues. If you think that Shaq might be your perfect match, apply today!February 28, 2025, 10:22 pm

Dapper gentleman!Meet Newton – The Dapper Gentleman! Looking for a dog with both style and smarts? Meet Newton, a handsome 3-year-old brindle Mastiff mix, weighing about 65 pounds. With his regal looks and impeccable manners, Newton is the definition of dapper—but despite his charm, he was overlooked at an overcrowded shelter.

Since he was found as an underweight stray, Newton is still filling out to reach a healthy weight. With continued love and care, he’s sure to thrive in a home that appreciates his charm, intelligence, and big heart. Ready to Bring Home This Dapper Gentleman?

Story
https://foha.org/pet/queen2023/ All hail me, Queen! My name is Queen, and I am a beautiful, super-sized pup with something of a regal flair. Being outdoors is where I truly come alive, and I absolutely adore going for walks. In fact, I can never get enough of them! Walking on a leash is second nature to me, and I'm always up for an adventure. Hiking is one of my absolute favorite activities, and I make a fantastic companion on those long, winding trails. There's something about the woods and parks that captivates me, and I relish the opportunity to explore nature's wonders. Splashing my paws in the streams and taking in all the different scents is pure bliss. Oh, and let's not forget my special talent for rolling in the grass-I just can't resist! Traveling in the car is a breeze for me, and I'm always on my best behavior. During the ride, you might find me gazing out the window, observing the world passing by, or chewing on a delicious treat to otherwise occupy my time. Even after a lengthy walk, I still have energy to spare. Spending time in the play yard, chasing balls, and simply hanging out with my favorite people is my idea of a good time. Now, when it comes to training, I'm highly motivated by treats. However, I could use some patient and consistent guidance from an owner who is experienced and familiar with my breed. I'm incredibly smart and eager to learn, although I must admit, sometimes I like to believe I'm the one in charge. With the right approach, I know I can become an obedient and well-trained companion. Given my size and enthusiastic approach to life, I'd be more successful with a dog closer to my size. And I would need proper introductions to make sure we're a good match! Additionally, a household without children would be most suitable for me. I thrive in an environment where I can be the center of attention and receive the love and care I deserve. If you're looking for a majestic and spirited canine companion who will make your outdoor adventures even more memorable, then I'm your girl. Together, we can conquer the world, one walk at a time. To make an appointment to meet me, please fill out an application (no obligation). Thanks for looking and hope to see you soon!

Good with kids, Needs experienced adopter, House-trained, Spayed or Neutered, Shots are up-to-date,
Story
Titan is a 1.5-year-old, energetic, and playful dog adopted from BARCS animal shelter in Maryland. He loves running outside, chasing balls and frisbees, and playing tug-of-war in the backyard. While he is crate trained, he barks loudly for the first few minutes when put in his crate. In December, he had two seizures in one day, but he has been fine since and is currently on seizure medication, which can be discontinued once his prescription is finished. Titan has a big personality and isn’t shy about showing his frustration he huffs and puffs dramatically when told “no.” He’s also a bit of a troublemaker, especially when it comes to stealing bread, which he has successfully done before, leaving the empty wrapper next to him as undeniable evidence. No matter how many times he gets caught, he still watches any bread in sight with a hopeful stare, always plotting his next move. Despite his mischievous side, he’s a lovable pup who enjoys treats like doggy ice cream and chicken sticks.
