The dog, nicknamed "King," was found in the southbound lanes of the highway in the area of the Martin Luther King on-ramp around 1:30 p.m. Wednesday.
A report came in of a dog on the highway, and an animal control officer was sent to rescue him.
During the search, he contacted a Delaware state trooper, who spotted the dog. The trooper stopped three lanes of traffic so King could be rescued.
The trooper put the dog in his cruiser and took him to the animal control officer, who then rushed the dog to an animal hospital.
Authorites believe King was thrown from a vehicle onto the road. He suffered a fractured pelvis.
King is a Male Miniature Pinscher. The SPCA believes he's between seven and 10 years old. He was wearing a thin red collar and a flea collar. He's on pain medication for his injury and will have to be on crate rest for six weeks.
The SPCA says his prognosis for recovery is good. If found, it is likely the owners would be facing charges.
"Somebody said to me the dog could have jumped out of a vehicle," said SPCA animal officer Nick Pepe. "If that were the case, someone would have been looking for him by now."
If you know anything about King, call the SPCA at 302-998-2281.
The SPCA is also taking donations to help pay the cost of King's care.
