Romain Grosjean won the GP2 sprint race in Turkey with a superb drive from seventh on the grid, but the race will be remembered for Bruno Senna's exit - when he hit a stray dog.
Adam Carroll led from pole, but his clutch failed almost immediately. Multiple pile-ups at Turn 1 and Turn 3 then brought out the safety car, with yesterday's podium finisher Andi Zuber the highest-placed casualty.
At the start, Vitaly Petrov had dived down the inside to grab the lead from third on the grid, ahead of Sebastien Buemi, Javier Villa and Grosjean.
Grosjean passed Villa at the chicane on lap four and quickly closed on Buemi, dispensing with him on the back straight two laps later.
Petrov put up a sterner defence, but Grosjean eventually passed him at Turn 12 at the end of lap 11.
Just after that, two dogs ran onto the circuit, and sixth placed Senna, who had worked his way up from 15th on the grid, struck one at high speed, smashing his car's right-front corner and leaving Senna livid.
The safety car was required again, as marshals rounded up the other canine track invader. At the restart, Grosjean caught Petrov napping, before pulling out a huge lead to the finish.
Petrov kept Buemi at bay for second, ahead of Saturday winner Giorgio Pantano, Mike Conway and Ben Hanley - both Britons doing well to score points from lowly grid positions.
Both Villa and Karun Chandhok should have finished in the points, but they both spun while battling with each other and would finish 15th and 12th respectively.
