Glastonbury police are investigating after someone left a dog at the Connecticut Audubon Society over the weekend.

Police said the female dog was found tied up to the door at the Audubon Society on Main Street.

Audubon society officials said they closed at 3 p.m. on Saturday and when staff arrived at 8:30 a.m. Sunday, the dog was there. Someone had already called police and staff arrived at the same time as animal control officials.

The Audubon Society does not offer services for abandoned pets, officials said.

Anyone who recognizes the dog should contact Glastonbury Animal Control at 860-633-7227.
