Plain pasta is harmless and cheese is a caution, but boxed mac and cheese is neither plain nor just cheese: the powder frequently includes onion and garlic powder, and the finished dish is a butter-and-salt delivery system.
Check Mac and Cheese for your dog

Why Mac and Cheese needs caution
The cheese-powder packet and many homemade recipes include onion or garlic powder: the ASPCA lists Alliums as toxic to dogs, and powdered forms are more concentrated than fresh. Add the butter and milk the box calls for and a stolen bowl is also a genuine fat and sodium load.
Signs to watch for
Gas, vomiting, loose stool; from onion/garlic powder in quantity (can lag by days): lethargy, weakness, pale gums
What to do next
A noodle or two needs nothing. For a bowl-level theft, check the ingredient list for onion and garlic powder and call your vet if they're there and the amount was real.
A few stolen noodles are a non-event. A full bowl in a small dog is worth a call, mostly for the Allium powder, secondly for the fat.
Can I treat this at home?
Yes, for a small taste: expect at most some gas and soft stool.
When should I call the vet?
A bowl or more in a small dog, an onion-heavy recipe, repeated vomiting, or weakness and pale gums in the days after.
Can I make plain mac and cheese for my dog?
You could: plain pasta with a little plain cheese skips the Allium problem. But it's empty rich calories a dog doesn't need. A better treat exists in your fridge for the same effort.
