Random question re: dogs and grapes

[chocolatechip]

Are all dogs affected negatively by grapes? 

 

I ask because we have a grapevine in our yard. I am positive our 11-yr-old dog has been eating the grapes that fall off the vine. Probably ever since she was a puppy. 

 

We have never noticed any ill effects. At all. 

 

:huh:

Too many grapes or raisins can kill a dog.

Grapes and raisins have recently been associated with the development of kidney failure in dogs. At this time, the exact cause of the kidney failure isn’t clear, nor is it clear why some dogs can eat these fruits without harm, while others develop life-threatening problems after eating even a few grapes or raisins. Some dogs eat these fruits and experience no ill effects—but then eat them later on and become very ill. Until the cause of the toxicosis is better identified, the safest course of action is to avoid feeding grapes or raisins to your dog. Dogs experiencing grape or raisin toxicosis usually develop vomiting, lethargy or diarrhea within 12 hours of ingestion. As signs progress, dogs become increasingly lethargic and dehydrated, refuse to eat and may show a transient increase in urination followed by decreased or absent urination in later stages. Death due to kidney failure may occur within three to four days, or long-term kidney disease may persist in dogs who survive the acute intoxication. Successful treatment requires prompt veterinary treatment to maintain good urine flow.

Our 15 yr old JRT ate our raisins from Raisin Bran all the time. We had no clue they could be bad for her. She never got sick.

Of course, she's also survived without incident on Dog Chow for 15 yrs (with table food)....

Now we are educated puppy owners and shocked the JRT survived us. :)

From Merck Veterinary manual "It is not known why many dogs can ingest grapes or raisins with impunity while others develop renal failure after ingestion. The condition has not been reproduced experimentally, although raisin extracts have been shown to cause damage to canine kidney cells in vitro."
