The horse named Dixie is in stable condition. A veterinarian says they will continue to monitor her condition in case it develops into pneumonia but she is expected to make a full recovery.
On Monday, Dixie wondered across the street to a neighbor's house on Hudson Pond Road, stepped onto the tarp covering the pool and fell through.
Fire and rescue crews were able to get her out within 30 minutes. Veterinarian Liz Lawrence told NBC 10 the horse was hypothermic but should recover.
