Story

Hi there… I’m Lazarus, a 1-year-old, 89 lb Mastiff mix with three legs, a giant heart, and a lot to say. I know what you might be thinking—but trust me, having only three legs doesn’t slow me down one bit. I still play hard, love big adventures, and put my whole soul into being the best boy I can be. Tug-of-war with rope toys? Absolutely. Chewing my favorite toys? One of my talents. Snacks? Let’s just say I’m very motivated by cookies and will happily work for them. I’m also a professional snuggler. If you’re cold, lonely, or just need a warm, loyal presence beside you, I’ve got you covered. And if you enjoy conversation, you’re in luck—I love to “talk” and tell you all about my day. Long car rides together are also my idea of quality time. I’m great with people and I like having other dog friends around too—it makes life more fun. I’m house trained, polite, and genuinely just happy to be included. I came from Louisiana, and while my past is a bit of a mystery, my future is wide open and full of hope. I’m neutered, microchipped, and up to date on my vaccines. My adoption fee is $415. I’m ready for a forever home where I can be loved exactly as I am—tripod, talkative, affectionate, and full of joy. If you’re looking for a resilient, goofy, deeply loving companion, I think we might be perfect for each other so apply for me, LAZARUS TRIPOD LOUISIANA, at ehrdogs.org.

He is passionate about learning. - Housetrained and very communicative about needing the bathroom. Will whine/grumble, give paw or look at door. - He is crate trained and loves his crate. He will crate himself to take naps throughout the day and also will tuck himself to bed when the sun goes down and sleeps through the night. - Not destructive in the home at all, even when left alone. No separation anxiety. - Walks nice on leash! Big sniffer. Knows heel. - Energy level is average/medium. Will match your energy to be very active or a couch potato.

Story

Meet Garcia Garcia is truly a survivor. He came to us from the brink of starvation and has fought his way back to health, confidence, and purpose. Now, at just 9 months old, he’s ready to become the incredible dog he was always meant to be. Garcia is a guardian-breed mix (Boerboel, Neapolitan Mastiff, Pit Bull, Cane Corso, and Rottweiler), and he carries all the traits that come with that: loyalty, intelligence, drive, and a strong desire for structure and guidance. He has been training daily with @honorbrightdogtraining and Janice, and he has absolutely flourished. Garcia looks to his people for direction, learns quickly, and thrives when given a job and routine. He has a lot of energy to burn and will do best in an active, experienced guardian-breed home that understands his needs. Garcia would love a large, securely fenced yard where he can run, play, and enjoy his beloved toys. He has done well with other dogs but would also be perfectly happy as your one-and-only. What he needs most is stability, consistency, and leadership. This special boy has overcome so much, and now he deserves a home that can help him continue growing into the confident, balanced guardian he’s meant to be. We are looking for a guardian-breed experienced home to complete Garcia’s journey. You must be over 21 to apply and live within 2 hours of the Lehigh Valley, PA area within NJ or PA.
