"She was dehydrated, she was having bloody diarrhea, pretty malnourished and in a weakened condition," Dr. John Rappaport of CARES said.
The boxer pit-bull mix was brought here by Jessica Meyer.
Jessica tells Action News she was driving home from work when she saw someone inside a blue station wagon simply toss a rolled up blanket from a passenger window, while the vehicle was still travelling approximately 25 miles an hour.
Jessica admits, at first, she thought the worst.
"I thought somebody threw a baby out, because it was in a blanket, so that was the first thing that came to mind," Jessica Meyer of Morrisville, Pa. said.
Instead, she pulled over to find the puppy.
The dog only suffered minor scrapes from the incident but Rowan was shaking, emaciated, and dehydrated.
Veterinarians diagnosed her with an intestinal virus and assume the owners didn't feel they had the means to care for her.
Now though, if they're caught, the dog's previous owners face animal cruelty charges and local authorities do plan on pressing charges.
Those same authorities want other pet owners to know that pet abandonment is not the answer.
"You can contact the local police department; the animal control officer can pick the dog up. You can contact the SPCA and they'll accept the dog, no questions asked," Officer Bill Smith of the Morrisville Police said.
Officials say Rowan will be at CARES a few more weeks until she is well enough to be adopted, but she should be just fine.
Anybody with any information regarding this case is asked to call the Morrisville Police Department.
