Swiss is among the gentler cheeses for dogs: aged enough to be nearly lactose-free and lower in sodium than most of the deli case. It's still concentrated fat, so the portion rules don't change.

Why Swiss Cheese needs caution
Aging leaves Swiss with very little lactose, and it runs lower in salt than cheddar or processed slices. The remaining question is plain fat: the ASPCA lists dairy among people-food risks, and rich cheese in quantity is a stomach-upset and, for prone dogs, a pancreatitis question.
Signs to watch for
Usually none; large amounts: gas, soft stool, vomiting
What to do next
Nothing for a bite or a slice. After a real quantity, skip other rich food for a day and watch for repeated vomiting.
