Grape toxicity in dogs is a serious issue that can arise from various sources. Dogs can become poisoned by ingesting grapes or raisins, regardless of whether they're seedless or seeded, commercial or homegrown, red or green.

Some common risk factors associated with grape poisoning include owner feeding the dog foods that contain grapes, leaving grapes out in a fruit bowl, and having open containers of trail mix with raisins. Spoiled grapes thrown in the garbage and grapes or currants growing in the garden can also be a hazard.

Here are some potential sources of grape poisoning:

Grape varieties that are toxic to dogs include seedless and seeded grapes, as well as commercial and homegrown fruits.

Red and green grapes, as well as raisins, have been known to cause poisoning in dogs.

Organic and non-organic grapes and raisins can be just as toxic, so it's essential to keep an eye on your furry friend's snacks.

Foods containing grapes, raisins, and currants, such as raisin bran cereal, trail mix, and granola mix, are all potential sources of poison.

Some dogs may be more sensitive to the toxic effects of grapes and raisins, so it's impossible to predict which ones will be affected.

Raisins, grapes, and currants are all toxic, but the reason why is still unknown.

Some researchers suspect that a mycotoxin, a toxic substance produced by a fungus or mold, may be the cause of toxicity in these fruits.

The toxicity of these fruits is a cause for concern, and exposure to them should be avoided.

Raisins and currants are often used in cooking and baking, but it's essential to be aware of the potential risks associated with consuming them.

Grapes, on the other hand, are a common ingredient in many foods and beverages, but their toxicity is still not fully understood.

It's worth noting that no toxic agent has been identified in these fruits, which makes it even more puzzling why they are toxic in the first place.

Grapes, raisins, and tamarinds belong to the Vitis and Tamarindus genera, respectively. These fruits are occasionally associated with renal failure in dogs.

The toxic principle in these fruits is thought to be tartaric acid, an organic acid present in high concentrations. Dogs poorly excrete organic acids because they lack the necessary transporters.

Tartaric acid accumulates in the proximal renal tubular cells of dogs, leading to renal failure. Affected dogs typically develop oliguric or anuric renal failure within 72 hours of ingesting these fruits.

The tartaric acid content of grapes, raisins, and tamarinds varies, resulting in variable effects following ingestion. More than one grape or raisin per 4.5 kg (10 pounds) of body weight may contain enough tartaric acid to pose a risk for renal effects in dogs.

If your dog has ingested grapes or raisins, it's essential to recognize the symptoms quickly. Vomiting is often the first sign, seen within 24 hours after ingestion.

A variety of symptoms are possible, including vomiting and/or diarrhea, hyperactivity, depression, and lethargy. Abdominal pain, fluid cessation, and loss of appetite are also common.

The symptoms can be similar to kidney failure from other causes, making diagnosis challenging. However, the presence of pieces of grapes or raisins in the vomit or feces can be a strong indication of grape toxicity.

A history of grape ingestion, signs, and blood tests are used to diagnose grape toxicity. Blood tests can show kidney failure with increases in BUN, creatinine, phosphorus, and calcium.

Here are the key symptoms to look out for:

Early diagnosis and treatment are critical in preventing kidney failure and death. If you suspect your dog has ingested grapes or raisins, seek veterinary attention immediately.

If your dog has ingested grapes or raisins, prompt GI decontamination is crucial to prevent absorption of the toxins. This can be achieved by inducing vomiting with emetic drugs like ropinirole, apomorphine, or 3% hydrogen peroxide.

Inducing vomiting is especially important if your dog has ingested a large quantity of grapes or raisins, or if diarrhea has developed within 12 hours after ingestion. In these cases, diuresis with aggressive IV fluid therapy for at least 48 hours is recommended.

Activated charcoal can also be administered to bind to the toxin in the dog's stomach and limit absorption. However, it's essential to note that the use of emetic drugs licensed for use in dogs should be prioritized over extra-label use of other drugs.

If your dog has ingested a large amount of grapes or grape-containing product, intravenous fluids will be necessary for at least 48 hours to help increase urine production, support kidney function, and flush the toxin out of the body.

Dogs that only ate a few grapes or raisins and received immediate treatment have an excellent prognosis. However, if the kidneys are damaged and no urine is produced, the prognosis is poor and fatality is likely.

Here is a summary of the treatment and prognosis for grape toxicity in dogs:

Remember, the level of toxicity in grapes is considered mild to severe, and immediate treatment can increase your dog's chance of survival. Any amount of grapes or grape-containing product is dangerous for dogs, so the best way to manage the condition is to avoid exposure.
