Parmesan is one of the more dog-tolerable cheeses: long aging removes nearly all the lactose. The catch is salt. Hard aged cheeses are among the saltiest foods in the kitchen, so a sprinkle is fine and a chunk habit is not, especially for small dogs.

Why Parmesan needs caution
Aging works in a dog's favor here: parmesan, asiago, and other hard cheeses carry almost no lactose, so the classic dairy stomach upset is unlikely. What aging concentrates instead is sodium. Dogs need far less salt than people, and the ASPCA lists excess salt among the people-food risks, with large amounts causing increased thirst and, at the extreme, tremors.
The rind and the wooden-spoon problem
Parmesan rinds are a favorite counter-surf prize. The rind is just harder cheese and is not toxic, but a swallowed chunk is firm enough to be a choking or gut-irritation risk in a small dog, the same mechanical concern as any hard swallowed object. Watch for gagging, repeated vomiting, or straining if a whole rind went down.
Signs to watch for
Usually none; after a large amount, increased thirst and urination, vomiting, or wobbliness
What to do next
Nothing to do for a sprinkle. For a real quantity, leave water freely available (never restrict it after salty food) and call your vet if your dog is small or seems unsteady.
A sprinkle of grated parmesan or a small nibble is a non-event for most dogs. The salt math only matters with quantity: a small dog working through a chunk of hard cheese, or salty cheese as a daily habit.
Can I treat this at home?
Yes. A sprinkle or a stolen nibble needs nothing beyond fresh water available.
When should I call the vet?
A large amount in a small dog, a dog with heart or kidney disease that ate a real quantity, or signs like nonstop thirst, vomiting, or wobbliness.
Is parmesan better for dogs than regular cheese?
For lactose, yes: aging removes most of it, so parmesan sits better than soft fresh cheese in lactose-sensitive dogs. For salt, no: it is one of the saltiest cheeses. Small amounts, occasionally, is the rule either way.
