Short answer
Yes, you can keep your dog away from ketchup with a few simple steps. Store the bottle in a sealed container on a high shelf or in a cabinet your dog can’t reach. Teach a reliable “leave it” command and promptly clean up any spills so there’s no temptation. If your dog does manage a small taste, watch for vomiting or diarrhea and call your vet if anything seems off.
