The dog, which the staff at Ramapo-Bergen Animal Shelter had named Grant, had to receive a blood transfusion. His urine and feces-matted fur had to be completely shorn.
Grant, the undernourished shi tzu that was pushed from a moving vehicle, is still very weak and animal shelter workers say the pup "uses what little energy he has to be affectionate."
An undercover investigation of 29 pet stores that sell puppies in New Jersey found that some are getting their animals from so-called puppy mills and not providing customers with proper breeding information for their dogs.
A number of recent animal hoarding, strays and pets being surrendered by owners has New Jersey shelters scrambling to make room for the influx in animals.
