The oil content adds a fat load that can upset the stomach or inflame the pancreas. 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 Italian Dressing. Dose-by-weight for the allium content, with effects that can take days to show. A dressed salad eaten off the counter is a more realistic exposure than most owners expect.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Caesar Dressing. A trace in a large dog is usually monitored. If a real amount was eaten, if your dog is small, or if you see dark urine, pale gums, or unusual tiredness over the next few days.
3. If the details are uncertain
Follow the first 10 minutes guide. Read the label for garlic and onion, note the amount eaten, and call your vet if it was more than a lick or your dog is small.
