Why Pasta Salad needs caution
The pasta is harmless; the dressing usually is not. Most recipes use Italian dressing or a vinaigrette built on garlic and onion powder, which damage red blood cells and can cause anemia, and the mayo-based versions add a heavy fat load. Some recipes also include grapes or raisins, which can cause acute kidney injury in dogs at any amount.

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 Macaroni Salad. Allium effects are by weight and can be delayed several days, so a bowlful in a small dog matters more than a forkful in a Lab. If raisins or grapes were in it, size does not protect the dog: that is an any-amount exposure.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Potato Salad. Only for a plain, undressed bite. Anything with dressing, onion, garlic, or dried fruit needs a call. Right away if raisins or grapes were present. Otherwise call if there was real onion or garlic content, if your dog is small, or if you see pale gums or dark urine over the next few days.
3. If the details are uncertain
Follow the first 10 minutes guide. Find out whether the recipe contained onion, garlic, or raisins, then call your vet with your dog's weight and the amount eaten.
