She and Poulain staked out the park on Tuesday night, trying to coax the dog into taking a lead, but without success.
Edwards says the dog wasn’t aggressive but seemed to lack trust, and to have avoided traps set by Hastings council staff.
Offered and eventually accepting treats, the increasingly malnourished dog accepted the lead and soon appeared comfortable with the new company.
By mid-afternoon it had been taken to a vet and found to be micro-chipped, sparking attempts to trace an owner.
Edwards said many people had shown their concern for the dog’s wellbeing and she hoped it would soon be fully recovered and in a suitable home.
“She’s asleep in my car right now,” she said. “She’s a lovely dog.”
Councils had by early evening been unable to comment on the situation due to the lateness in the day.
