Sarah Snyder is desperate to find her best friend and lost service pig, Demeter.
She disappeared Wednesday night in the area of Mathis Road and Interstate 37 in south Bexar County.
"We were just picking stuff up from the ground and all of a sudden we noticed she was missing," said Snyder.
This is the area where Demeter was last seen. She was wearing a pink harness and attached to it a pink leash. Sarah said Demeter is domesticated so she's definitely not use to being out in the cold.
With temperatures dropping Thursday night, Snyder is fearful what will happen to her.
"She's spoiled. She sleeps in bed under the covers or she sleeps in a bed with two dog pillows a comforter sheet and three blankets," said Snyder.
Snyder got Demeter to help her deal with her health issues. By her side, Demeter allowed Snyder to live a life virtually without any medication.
"She's my therapy animal, she helps me with anxiety issues and I have two chronic muscular pain diseases and she alerts me to those before they get to be too bad," said Snyder.
Snyder said life is much more difficult without her service pet by her side.
"If somebody has her I just want her home," said Snyder.
Demeter is described as being about 18 inches high and 65 pounds. She also is black on top and has a white belly. There is a $300 reward for her return. If you've seen her, please call her owner, Sarah Snyder at 210-286-5820.
