Short answer
Your dog is fine. Plain cooked cod is safe and low-fat for dogs. Just check that it wasn't fried or coated in batter, and avoid sharing any seasoned or buttery pieces. Offer your dog a little fresh water, watch for any unusual stomach upset, and call your own vet if anything seems off.
