Sparky was one of the minor characters in the Smosh franchise. He was Ian's little-recurring pet dog.
Sparky only had one Smosh video about him, and then was mentioned in "Ian's Birthday", when Anthony thought he had run over and killed Sparky, but it was really Ian's sister. Since then, he has only been mentioned and shown in a cameo in "Smosh- Reunited?". In "Lizard Rabies!" Ian claimed Sparky was run over, but it was unknown if Sparky really died by the time the video was made. Another dog was shown as him in "My Morning Routine", possibly meaning that the original Sparky has died. The dog that appeared in "My Morning Routine" also appears in "This Video is Offensive".
