Sadie Says “Don’t Give Your Dog Raisins”

We’ve all received the forwards that warn us to not open certain e-mails, however this is one of those e-mails that is based in fact and can be very scary for my doggy brothern.

Raisins and grapes rate right up there with chocolate and onions as food that should be kept to the humans and not shared with the four-legged friends.

We received this e-mail tonight:

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 that 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 IV fluids at 1 ¡Ç 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 incr ease 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 including our ex-handler’s. Any exposure should give rise to immediate concern.

Could it be a scam? Maybe, however long-time readers know that I’m from Danville and Dr. Morris is a veterinary in Danville. So I’m game for believing this was written by her.

So, keep and eye out for my friends.
