The dog, who has been named 'Boss,' was found wandering and still bleeding from that gunshot wound last week on Route 9 in New Gretna, Burlington County.
The couple who found the dog took him to Stafford Veterinary Hospital in Manahawkin.
Boss had to have several teeth removed because they were shattered by the bullet. He also swallowed bullet fragments and was having trouble eating.
"But now he's eating great. He's active as you can see. The next step is to get surgery on his injured knee," said Dr. Michael Pride.
The vet discovered the dog also had a torn ligament on his hind leg.
Donations have been pouring in since word got out about Boss. Now all of his surgeries and treatments will be covered.
The investigation into the shooting of the dog continues.
