this is completely true.

WARNING Dog Owners
This week I had the first case in history of raisin
toxicity ever seen
at MedVet.
My patient was a 56-pound, 5 yr old male neutered lab mix who ate half a
canister of raisins sometime between 7:30 AM and 4:30 PM on Tuesday. He
started with vomiting, diarrhea and shaking about 1AM on Wednesday but the owner
didn't call my emergency service until 7AM.
I had heard somewhere about raisins AND grapes causing acute Renal failure
but hadn't seen any formal paper on the subject. We had her bring the dog
in immediately. In the meantime, I called the ER service at MedVet, and
the
doctor there was like me - had heard something about it, but....
Anyway, we contacted the ASPCA National Animal Poison Control Center and
they said to give I V fluids at 1 ½ times maintenance and watch the kidney
values for the next 48-72 hours.
The dog's BUN (blood urea nitrogen level) was already at 32 (normal less
than 27) and creatinine over 5 (1.9 is the high end of normal). Both are
monitors of kidney function in the bloodstream. We placed an IV catheter and
started the fluids. Rechecked the renal values at 5 PM and the BUN was
over 40 and creatinine over 7 with no urine production after a liter of fluids.
At the point I felt the dog was in acute renal failure and sent him on to MedVet
for a urinary catheter to monitor urine output overnight as well as overnight
care.
He started vomiting again overnight at MedVet and his renal values have
continued to increase daily. He produced urine when given lasix as a
diuretic. He was on 3 different anti-vomiting medications and they still
couldn't control his vomiting. Today his urine output decreased again, his
BUN was over 120, his creatinine was at 10, his phosphorus was very elevated and
his blood pressure, which had been staying around 150, skyrocketed to 220.
He continued to vomit and the owners elected to euthanize.
This is a very sad case - great dog, great owners who had no idea raisins
could be a toxin. Please alert everyone you know who has a dog of this very
serious risk. Poison control said as few as 7 raisins or grapes could be
toxic.
Many people I know give their dogs grapes or raisins as treats. Any
exposure should give rise to immediate concern.
