Dried forms are 4-5x more concentrated than fresh grapes by weight. Cream of tartar is a pure tartaric acid salt and any amount is an emergency.
Count pieces if you know how many were eaten; switch to grams if you measured or weighed the amount.
How many individual grapes, raisins, or similar pieces your dog ate.
Raisin size affects the gram total. If unsure, choose Standard.

  • Your dog received approximately 1.00 g/kg. The Merck Veterinary Manual risk line - more than one grape or raisin per 4.5 kg of body weight - works out to 0.22 g/kg for this food.
  • At 10.0 kg, that risk line is about 2.2 g of raisins, roughly 2.2 pieces.
  • The consumed amount is about 451% of that risk line, so enough tartaric acid may have been eaten to injure the kidneys.
  • No safe dose is known. The ASPCA Animal Poison Control Center and the Cornell Riney Canine Health Center both advise treating any grape or raisin ingestion as potentially serious, because tartaric acid content varies from 0.35% to 2% between fruits and individual sensitivity varies too.
