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.

Sayreville, NJ
Size
(when grown) Large 61-100 lbs (28-45 kg)

Spayed or Neutered, Shots are up-to-date,
Story
Sasha is a sweet female Mastiff mix, 69 lbs and about 1½ years old, who is looking for a safe place to land. She was found as a stray and is believed to have possibly been hit by a car. A veterinary exam showed no broken bones, which is great news, but she is still being monitored for any possible after effects.Sasha is a bit timid at first, which is understandable given what she has likely been through. With a slow approach and a calm, gentle greeting, she begins to relax and show her softer side. She walks well on a leash and seems to appreciate quiet reassurance.As we spend more time getting to know Sasha, we will continue to share updates about her personality and needs. For now, she is a gentle soul who could really use patience, kindness, and a loving home.If you are interested in meeting Sasha, please complete an Interest Form. An adoption counselor will contact you to schedule an appointment.February 13, 2026, 4:51 pm
