Grapes and Dogs - Finally Some Answers!

Grapes and Dogs - Finally Some Answers!

From Episode 172 on the ECC stream. With Dr Tina Wismer.

Making a 30 kg dog puke because it ate 1 grape always feels a bit excessive, right? But until recently, because we had no idea of what was actually causing the kidney damage, never mind how much of it was considered a toxic dose, that was just what we had to recommend. But no more!

Toxicologist Dr Tina Wiser told us in the episode recorded at IVECCS that:

  • We now have a pretty good idea what the toxin is in grapes: it’s tartaric acid. 

  • We have some dosage guidelines on when we should make dogs vomit: 

    • If you’re patient has eaten more than one grape or raisin per 5 kg/ 10 pounds of dog, or 

    • more than 2 COOKED grapes or raisins (eg hot cross buns, puddings etc) per 5kg/ 10 pounds per dog, you should make it vomit. Less than that - you can chill a bit.
