Per the Merck Veterinary Manual: " In general, more than one grape or raisin per 4.5 kg (10 pounds) of body weight may contain enough tartaric acid to pose a risk for kidney injury in dogs."
My dog ate 50 or so raisins (approx 100 grams by package weight) and it didn’t even disrupt his shits. The fear mongering on the internet had me ready to put him down.

TFW you can’t tell the difference between fear mongering and cautionary advice.
Also kidney damage isn’t going to do a whole lot to acute digestive health
I’ve read that some dogs are more tolerant, and some die from a single grape.
