Tanner is a handsome boy! He loves to take walks and lean into you for pets. He is a great car rider and really doesn't care where you are headed - he just wants to go along. He gets along with other dogs, but doesn't actually need a canine companion. He is not all that playful. He would love to be doted on and receive all of your attention. He is a pretty low maintenance dog with a good attitude.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=41

Story
Hello there, I'm Mark! I may be young, but I've got a heart full of love to give. Every morning, I wake up excited for the day ahead. I love playing with my favorite chew toy, but what I really crave is a good game of fetch with a human friend. I'm a quick learner, too! I've already mastered 'sit' and 'stay', and I'm eager to learn more. I promise to be your loyal companion, always ready for an adventure or a cozy nap on the couch. I'm not just looking for a home, I'm looking for a family. Adopt me and let's create a lifetime of wonderful memories together.

Story
Rosie is a sweet, loving pup looking for the right home where she can feel safe, comfortable, and loved. She came into our lives in February after showing up in a family member’s yard. After several attempts to locate her previous family were unsuccessful, we welcomed her into ours. Rosie is incredibly affectionate with her people and has so much love to give. Unfortunately, she has had conflicts with our other dog that have escalated into fights. During one incident, a family member was accidentally bitten while trying to physically break up the dogs. Because of this history, we believe Rosie would do best as the only dog in a home with an experienced, responsible owner who can provide structure, patience, and lots of love. This is an incredibly difficult decision for our family, and our priority is finding Rosie the right home where she can thrive.

Story
Currently fostered in: Brooklyn Park, MD 💙Meet Jackson!💙 Some dogs are content with minimal human interaction. Some dogs enjoy their personal space. Jackson? He has never heard of either of those things. This big, goofy teddy bear adores people, has personality for days, and has one of the sweetest hearts you'll ever meet! At 2.5 years old and about 70 pounds, Jackson firmly believes he is the perfect size to be your personal shadow, weighted blanket, emotional support buddy, and full-time best friend. He takes the title 'sidekick' very seriously. Privacy? Never met her. Getting up to grab a snack? He's coming with you (and wants one too) Going to run errands? He's by his leash ready to go! Need to use the bathroom? Well... Jackson believes that's a team activity too. This all means one thing: Once Jackson bonds with you- you've got the most loyal best friend for life. 💙ENERGY AND PERSONALITY💙 Jackson is everything people love about big dogs— equal parts sweetheart and goofball! He will make you laugh with his oversized puppy antics and his determination to convince you that he is lap-dog sized. He adores meeting new people, listens well, and has a happy-go-lucky outlook on life that makes everyone fall in love with him. Jackson also loves toys, bones, car rides, naps in his humans bed, and is 100% convinced that every snack in your hand was probably meant for him. (Honestly...he makes a really compelling argument.) Jackson has a medium/balanced energy level and is happy to lounge around OR go on an adventure. He doesn't care where you're going- he's just so grateful he gets to go with you! 💙SOCIAL LIFE💙 Jackson is known to quickly wins hearts whereever he goes. He gets along very well with other dogs, though his play style is best described as "VERY enthusiastic." He'd love a larger canine friend who enjoys roughhousing as much as he does or one who doesn't mind his goofy antics. He'd also be perfectly happy soaking up all of your attention as an only dog. 💙IDEAL HOME ENVIRONMENT💙 Like many rescue dogs, Jackson is still learning that being alone isn't so scary and that his humans will always be back for him. He would do best in a home where someone is home often, or where they can make arrangements for him to spend the day with someone while they are at work (i.e: doggie daycare, hanging out with a family member/friend/sitter, etc.) After spending so much of his life without a family of his own, Jackson's hoping for a home that understands he's still healing from his rough start, will be patient as he continues to build confidence, and won't mind having a devoted sidekick who thinks life is better together. Jackson has brought so much joy to his foster home, so we know he will bring a ton of joy to your home too! At the end of the day, Jackson is just a big sweet softie that has waited far too long for a furever family that shows him endless love and safety. Jackson has spent long enough wondering when it will finally be his turn. If you're looking for a dog who will love you with his whole entire heart every single day for the rest of his life... Jackson has been waiting his whole life for you. 💙INCLUDED VETERINARY CARE💙 Jackson is up to date on vaccinations, neutered, microchipped, and receiving heartworm, flea, and tick preventatives along with routine parasite treatments and yearly routine heartworm/lyme testing.
