Grapes are Toxic to Dogs

Located in wine country, Middletown Animal Hospital has seen first hand the results of a dog who has eaten grapes in the vineyard. A grape toxicity can lead to kidney failure, with typically the signs of vomiting and diarrhea occurring a few hours after ingestion. Lethargy and a loss of appetite also can be seen, along with a lack of urine production. Raisins can also be toxic. Since they are dried grapes, they are toxic in a smaller quantity. The toxic dose for grapes is about 1⁄2ounce per pound of body weight, but that can vary, so any consumption should be taken seriously.

The doctors at Middletown Animal Hospital suggest that if vomiting can be induced within an hour of an ingested toxic substance, then chances are good that the toxin will not have detrimental effects on the patient. Please call us immediately as one must be cautious in using hydrogen peroxide to self induce vomiting at home. The actual suggested dosage to induce vomiting is 1ml per pound, and never give a large dog more than three tablespoons.

As with most toxicities, time is of the essence.  Your dog should be seen by a veterinarian to avoid irreversible kidney damage.  Middletown Animal Hospital usually has openings for same day for appointments or can interrupt normally scheduled appointments for an emergency.  You will expect to have bloodworm run, a urinalysis, some fluids to flush the kidneys and some activated charcoal to bind up any toxins. A follow-up blood panel might be warranted in a day or two to ensure that kidneys are not negatively affected.  Keep your dogs out of the vineyards!
