Why Feta needs caution
Brining loads feta with sodium: the ASPCA lists excess salt among people-food risks, with large amounts causing increased thirst and, at the extreme, tremors. Feta is also relatively high in fat and retains more lactose than aged cheeses, so it stacks all three dairy concerns in one crumble.

The salad problem
Feta usually arrives in company: Greek salads bring red onion, and Mediterranean dishes bring garlic and olives. Onion is the ingredient that turns a cheese theft into a vet call. If the feta came off a plate, reconstruct the plate.
Signs to watch for
Increased thirst, gas, loose stool; large salty amounts: vomiting, wobbliness

Check the exact item or ingredient before assuming two similar exposures carry the same risk.
What to do next
For a crumble, nothing. For a block-sized theft, keep water freely available (never restrict it after salty food) and call your vet if your dog is small. Check whether onion came along for the ride.

A closer look at feta
Brining loads feta with sodium: the ASPCA lists excess salt among people-food risks, with large amounts causing increased thirst and, at the extreme, tremors. Feta is also relatively high in fat and retains more lactose than aged cheeses, so it stacks all three dairy concerns in one crumble. The details below use the specific facts for this exposure, rather than treating it like every other food question.
1. Start with the exact exposure
For a closely related comparison, read Goat Cheese. A few crumbles are a non-event. A block is a real salt load for a small dog, and that's the case worth a call.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Parmesan. Yes, for small amounts: fresh water, and expect possible loose stool. A block in a small dog, nonstop thirst with vomiting or unsteadiness, or any feta that came with onion-heavy salad.
3. If the details are uncertain
Follow the first 10 minutes guide. For a crumble, nothing. For a block-sized theft, keep water freely available (never restrict it after salty food) and call your vet if your dog is small. Check whether onion came along for the ride.

Marginally: the brine itself is salt water, and lapping it up adds sodium with no cheese to slow it down. Dump brine down the drain, not into reach.
