Animal-welfare officers were investigating the discovery Wednesday evening of a dead dog hanging from a tree in the Bridesburg section of Northeast Philadelphia.

The dog was discovered with a stick shoved down its throat, the Pennsylvania SPCA said.  The dog was found by visitors to a park near 5601 Tacony Street, said Wendy A. Marano, spokeswoman for the Pennsylvania SPCA.  It was not immediately known how long the dog had been dead and hanging from the tree, Marano said. - Robert Moran
