Cat food is not toxic to dogs, but it is much higher in protein and fat than dog food, so a dog raiding the cat's bowl can end up with vomiting, diarrhea or — with enough of it — pancreatitis. Feed the cat somewhere the dog cannot reach.
Don't make it a habit. Watch for vomiting, diarrhea or a lost appetite over the next day and call your vet if it doesn't settle or your dog seems unwell.
Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
If you're sharing food because you want to treat them, a treat formulated for dogs does the job without the guesswork.
