We heard it on the grapevine
As much as veterinarians warn us about chocolate, onions, garlic and anti-freeze, you may not know that large amounts of grapes or raisins can prove deadly to your dog, too. The ASPCA Animal Poison Control Center (APCC) began a study after receiving a large number of reports of dogs developing kidney failure after eating large quantities of grapes and raisins. Agility competitor Kate Prosser found out the heartbreaking way when her five year old Vizsla Anya died after eating a 500g bag of raisins.
Always happy, Anya had qualified for this year's ABC final. She ate the raisins on the Saturday afternoon, but the Kate was not very worried as she didn't realise how toxic raisins could be.
On Sunday, 12 January 2003, the dog was taken to the vet because she was very ill, vomiting a lot and not drinking. Kate mentioned to the vet that she had read an article somewhere that raisins could be toxic to dogs whereby the vet replied he had never heard of that. He did not bother to check with a poison centre and gave the dog an injection to stop it vomiting with some anti-emetics!
Anya was admitted to the vets and put on a drip the following day (Monday) after Kate got them to take a blood sample which showed she was in acute renal failure. She seemed better in herself by Wednesday, but her blood tests showed her toxin levels were getting worse and that her kidneys were not working. After Anya collapsed completely and could not stand, Kate took her to Bristol for peritoneal dialysis as her own vet was unable to perform this operation. This was the only hope left.
They had tried everything to save her but she died on Wednesday night.
Veterinary toxicologists found that all dogs in the reports showed signs of vomiting within six hours of eating from nine ounces to two pounds of grapes or raisins. Other signs included diarrhea, anorexia (loss of appetite), lethargy, abdominal pain, and kidney failure. Treatment with intravenous fluids and other medications only resulted in recovery of about half of the cases. The other half did not recover.
What exactly is the toxic
Please take the threat of poisoning from raisins seriously. As with most of these things, eating a few seem to be harmless and the quantity that will prove fatal varies hugely from dog to dog. If your dog is sick after eating them, get them to a vet and insist on a blood test - the sooner they can be attached to a drip the more chance they have of surviving.

From Alison Stewart...
My vet was unaware of the fact grapes are toxic in large quantities, but fortunately for me the nurse had read something in passing so bloods were taken very quickly. It is still too early to say what Scooby’s outcome will be, but the death rate from cases in America would appear to be 50:50.
As yet the reasons are unknown as to what causes the problems but pesticides and sprays have been ruled out.
If this could just get people talking and thinking twice of using these foods as training treats, it would be a great start to preventing these deaths or at least getting them treatment early. (21/10/05)
Postscript: Just a quick note to let everyone know that Scooby seems well on the way to making a full recovery. (03/11/05)

Although it is not a lot, I just want to say thanks because it may have gotten really bad at some point. I also keep the raisins with Noochie's cookies so a mistake could have occurred. God bless. (06/03/03)
