Story
She-Ra is a female Mastiff. She is approximately five years old, and currently weighs 93 pounds. She was brought to our shelter on 11/17/25 after being found in unincorporated Livermore. She hasn't been reclaimed by her previous person, so she's now looking for a new home! She has been vaccinated, and will be spayed and micro-chipped before going to her new home. Her adoption fee is $35, plus licensing (if applicable), plus the cost of her spay surgery.
