The snake, believed to be a rare copperhead, was reported along Attleboro’s Ten Mile River near Milk Street, officials wrote.

ATTLEBORO, Mass. — A supposedly venomous snake that bit multiple dogs in Bristol County was a case of mistaken identity. According to MassWildlife, recent reports of a copperhead in the City of Attleboro were unfounded, and the snake in question turned out to be a northern watersnake.

The snake reported to have bitten two dogs in Attleboro, MA on July 9 is most likely not a rare venomous snake, state wildlife officials said.
