Continuity mistake: There are several close up shots of the syringe that Dr. Hamilton is using to threaten Pete with and you can see that it is made of plastic. Clark uses his heat vision to overheat the syringe causing it to burst but the sound the syringe makes when it bursts is that of a glass syringe and not the plastic one he was actually using.
Continuity mistake: Clark tries to talk to Pete into helping him find his ship. As Clark was talking about the driver, we see the cover to Pete's locker in the foreground. Cut to a different angle and now Pete's left hand is on the locker and it wasn't there in the previous angle.
Continuity mistake: When Dr. Hamilton was about to pour liquid kryptonite on Clark, Pete hits him on the back and he goes crashing onto a table knocking everything on it off the table. Yet later we see an open bottle of liquid kryptonite on the edge of the table (which was cleared by the doctor earlier) dripping onto the doctors forehead.
Continuity mistake: At the collision, Pete looks out over the cornfield and sees the flashing turn signal of the truck but not its headlights, which should be brighter. (00:03:20)
Continuity mistake: After Pete confronts Clark about the missing space ship in his tool shed, Pete gets into his car and we see Clark put his right hand on the door of Pete's car. Cut to a different angle as Pete drives away but now Clark's hand is no longer on the door.
Answer: In the comics, Krypto is a dog from Krypton who was used as the passenger in a test launch by Jor-El, Superman's father, before he launched the actual rocket taking his infant son to Earth. Krypto's capsule was involved in a mishap, sending it out of Kryptonian orbit and eventually found its way to Earth where he linked up with the young Clark Kent. Like any native of Krypton, Krypto has superpowers on Earth. In Smallville, the dog is a standard Earth dog who has been experimentally injected with kryptonite, giving him super-strength for a limited period of time, who escapes and links up with Clark (who suggests the name Krypto, ostensibly because of the dog's cryptic origins). It doesn't take too long for the dog's strength to fade, and the Kents decide to keep him, although they ultimately name him Shelby, after a dog that Martha Kent had in childhood.
