East Hartford Lt. Joshua Litwin said animal control is investigating and there had been no arrests as of Monday morning.
Litwin tells the Hartford Courant (https://cour.at/2T5DZ3z) the dogs began fighting at Labor Field about 11:45 a.m. Sunday.
He wasn’t sure what breed the other dog was.
But he says its owner pulled out a knife and began stabbing the pit bull in an attempt to get it to stop fighting with his dog.
The bleeding pit bull was taken to a veterinary hospital, where it died.
