The New Jersey Society for the Prevention of Cruelty to Animals has charged Kisha Curtis with four counts of animal cruelty.
Society spokesman Frank Saracino told The Star-Ledger of Newark the 28-year-old could face up to six months in jail, a $1,000 fine or community service if convicted.
A custodian found the red pit bull mix, who has been named Patrick, in a trash bag on March 16.
The dog was taken to Garden State Veterinary Specialists in Tinton Falls, where it was determined the dog was severely anemic and malnourished.
Doctors say Patrick will be put up for adoption if he continues to improve and recovers.
