Story
Sasha is a sweet female Mastiff mix, 64 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.January 21, 2026, 2:02 am
