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 4, 2026, 1:28 pm

Story

My tail starts wagging the second I hear “Peanut Butter Jelly Time!” A good meal makes me very happy (I’m working on filling out these long legs), and I’ll never say no to a big bowl of water. I take naps very seriously. Cuddles, gentle massages, and cozy downtime? That’s MY love language! Hi. I’m Duke I’m a loving, cute, sleepy guy who’s looking for a family to call my own.I love going on walks (even if I still pull a bit because I’m excited to say hi), then coming home to do what I do best: rest, snuggle, and keep you company. My energy level is pretty low - I’m more of a chill buddy” than “marathon runner.” At home, I’m super sweet and really want to please you. I’m still learning my commands (food helps ), but I’m trying every day. I listen when I’m told to leave things alone, play gently with other dogs, and I’m respectful with cats - even if I really want to be friends. I’ll sit on the couch and watch the cat like it’s my favorite show. I sleep in my crate at night and during the day, but I’m still learning that it’s a safe space - especially when treats are involved. I’d do best with someone patient, calm, who has experience with bigger dogs like me - who are still learning!I’m only 2 years old and I weigh about 120 lbs, but I’m on the skinny side and working on gaining healthy weight with regular meals. What I really want is a home with chill energy, consistency, patience, and LOTS of affection. Someone who understands that I’m a big, gentle guy still learning the world, and who’s willing to grow with me!If you think I might be your DUKE, apply to adopt me at rescuecity.nyc/adopt ##2646835##
