Are raisins poisonous to dogs?

Question

Someone called Clark Howard, the consumer radio talk show host, and told him that raisins almost killed his dog and the vet said they were toxic to dogs. Does this make sense? Why?

Answer 1

Raisins and grapes in any form, have been shown to cause kidney failure in dogs. The scientists don't fully understand why, but it is happening all over the world, and is well documented..One of my dogs just loves grapes, so I was dismayed to learn of this..I don't allow them any more...sigh

WARNING Dog Owners - Confirmed at:

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.
Macadamia nuts can cause vomiting, disorientation, stomach pain, and muscle stiffness or weakness in dogs.

Answer 3

Although the minimum lethal dosage is not known, grapes and raisins can be toxic to dogs when ingested in large quantities. The symptoms are gastrointestinal signs including vomiting and diarrhea, and then signs of kidney failure with an onset of severe kidney signs starting about 24 hours after ingestion. The amount of grapes eaten varied between 9 oz. and 2 lbs., which worked out to be between 0.41 and 1.1 oz/kg of body weight. It has been reported that two dogs died directly from the toxicity, three were euthanized due to poor response to treatment and five dogs lived.

Due to the severity of the signs and the potential for death, the veterinarians at the National Animal Poison Control Center (NAPCC) advocate aggressive treatment for any dog believed to have ingested excessive amounts of grapes or raisins, including inducing vomiting, stomach pumping and administration of activated charcoal, followed by intravenous fluid therapy for at least 48 hours or as indicated based on the results of blood tests for kidney damage.

Answer 4

According to the ASPCA Animal Poison Control Center, grapes and raisins are dangerous for dogs. After ingesting raisins or grapes in the amounts ranging from 9 oz. to 2 lbs., a veterinary toxicologists' report stated that symptoms included vomiting, kidney dysfunction, diarrhea, anorexia, lethargy and abdominal pain. After aggressive treatment including intravenous fluids and medication, only half of the canines survived. If you find that your dog or puppy has ingested raisins or grapes, call your veterinarian immediately.
