Story
Hi, I’m Garnet! I’m a sweet, affectionate 2-year-old girl who loves spending time with my people. One of my favorite things is cuddling on the couch, but I also enjoy playing with toys, chewing on bones, and just hanging out indoors with my family. My former family shared that I did well in the home and already knew some commands. I’m very food motivated, which means I enjoy learning new things and …perhaps a fun way for us to bond! I can be a little shy when meeting new people at first, but with a little time and patience, I start to warm up and show my sweet, playful side. I really love being close to my people. I shared my previous home with other furry friends, but honestly, I will be happiest soaking up all the love and attention as the one-and-only furry friend in my home. If you’re looking for a loyal companion to cuddle with, learn new things together, and share lots of happy moments, I just might be your girl!

Finn AKA Gage JuM

Mastiff Shepherd (Unknown Type)

Male, 7 yrs 3 mos
Von Ormy, TX
Size
(when grown) Large 61-100 lbs (28-45 kg)
Details
Good with dogs, Spayed or Neutered,
Story
Finn may look like a rockstar with his striking Mastiff–Shepherd good looks, but at heart, he’s a big, soft lovebug. Weighing in at about 60 pounds, Finn has grown into a handsome boy with a beautiful gray and tan coat, soulful eyes, and an even bigger personality. Despite his star-quality appearance, Finn is more of a laid-back, easygoing guy—think Eeyore vibes, but with engines revved and ready to love. From the moment he wakes up, he’s prepared to shower his people with affection… and trust us, it’s A LOT of love! Finn does well with other dogs and does need a slow, proper introductions to new friends—both two-legged and four-legged. Once he knows you, he loves you deeply. He’s happiest when he has a buddy (human or canine) to share his world with. Affection is Finn’s specialty. When someone comes to greet him, he lights up, runs over with enthusiasm, and hands out slobbery kisses and big hugs like they’re backstage passes. His joy is genuine, his heart is huge, and he’s always thrilled to see his people. If you’re looking for a big, lovable, slightly goofy rockstar who will adore you endlessly, Finn is ready to take center stage in your heart. Local adoption only $200 (in TX)

Story
Hi, I’m Luke, and I’m a big, lovable boy tipping the scales at just over 100 lbs! Don’t let my size fool you—I’m a happy, easygoing pup who just wants to play, explore, and cuddle. I’m all about the good things in life: squeaky toys, water play, long walks, and best of all—snuggle time on the couch. I’m a pro at giving hugs (though I’m working on not jumping up too hard to give them—oops!). I get along great with other dogs and kids, but because of my size and enthusiasm, I’d do best with older children who won’t get accidentally knocked over during playtime. I’m crate trained, housebroken, and walk nicely on a leash—unless there’s a squirrel… then it’s game on! I do have a slight prey drive, so a little guidance goes a long way. If you’re looking for a big-hearted, playful companion to fill your home with love (and maybe take up some space on your couch), I’m your guy. Let’s make forever happen! 🐾 Local adoption fee is $200(in TX) Out of state adoption fee is $450 (includes transport to your area)
