Examination of the corpses now point toward the animals being foxes, officials say.
Officials in Lehigh County now say 11 skinned animals dumped near a public park in Lower Macungie Township appear to be foxes, not puppies.
Lehigh County Humane Society shelter manager Cary Moran says necropsies conducted today show that at least one animal was shot and the others might have been trapped.
A state game commission website says fox hunting is legal in Pennsylvania from October through February.
Animal welfare officials had initially feared the animals were puppies. But Moran says their eye sockets and teeth more closely resemble foxes.
DNA tests are under way to confirm their species.
The discovery of the bodies Friday came the same week another animal was found skinned, with its feet cut off and rope tied to one leg, about 20 miles away in Lynn Township.
