Can Dogs Eat Currants?

When it comes to feeding our dogs, we often want to share the foods we love. However, not all foods safe for humans are safe for dogs, and some can even be toxic.

Currants, in particular, fall into this category and pose unique risks for our furry companions. This article explores why dogs should avoid currants, the dangers they present, and what to do if your dog accidentally ingests them.

What Are Currants?

Currants refer to several types of small berries, often confused with each other. In North America, the term “currants” can mean two different things:

• True currants (from the Ribes genus), which include red, black, and white currants commonly used in jams and desserts.
• Zante currants, tiny dried grapes from a variety of seedless grape known as Black Corinth.

True currants (from the Ribes genus) are generally not considered toxic to dogs in the same way that Zante currants and grapes are.

However, it’s still best to be cautious, as some dogs can have sensitivities or adverse reactions to various fruits, including true currants, especially if they are not used to them. But overall, true currants don’t carry the same kidney failure risk that Zante currants and grapes do.

In this article, we focus on Zante currants due to their presence in many commercial foods and treats.

Are Zante Currants Safe for Dogs?

The short answer is no. Dogs should not eat zante currants, whether they are fresh, dried, or in any form. The toxicity level of zante currants in dogs is high and can lead to serious health complications.

Even small quantities have been known to cause adverse reactions.

Why Are Zante Currants Toxic to Dogs?

The exact substance in zante currants (and grapes, which are closely related) that causes toxicity in dogs remains unidentified.

However, research and veterinary observations confirm that ingestion of these fruits can lead to kidney failure in dogs. Zante currants and grapes are toxic to dogs regardless of size, age, or breed, though some dogs may be more sensitive than others.

Symptoms of Zante Currant Toxicity in Dogs

If a dog consumes zante currants, symptoms of toxicity can appear quickly, usually within a few hours. Some signs to watch for include:

• Vomiting: Often one of the first symptoms, it can occur within 2-3 hours after ingestion.
• Diarrhea: Gastrointestinal distress often follows vomiting.
• Loss of Appetite: Dogs may show disinterest in food, which is unusual if your dog is typically eager to eat.
• Lethargy: Dogs may appear overly tired, listless, or unresponsive.
• Abdominal Pain: You might notice your dog whining, pacing, or holding its belly, indicating discomfort.
• Increased Thirst and Urination: In severe cases, kidney distress may cause increased thirst and an unusual frequency of urination.

Risks of Zante Currant Consumption: Kidney Failure in Dogs

One of the most severe outcomes of zante currant ingestion is acute kidney failure, a potentially life-threatening condition if not treated promptly. Kidney failure impairs a dog’s ability to filter toxins from the blood, resulting in dangerous health risks.

Even if the dog seems fine initially, zante currant ingestion can lead to delayed toxicity, with kidney-related issues appearing days later.

What To Do if Your Dog Eats Zante Currants

If you suspect or know that your dog has consumed zante currants, act quickly:

• Contact Your Veterinarian: Immediate consultation with a veterinarian is essential. They may advise you to induce vomiting, but this should only be done under professional guidance.
• Monitor Symptoms: Keep a close eye on your dog for any signs of distress, especially vomiting or lethargy.
• Visit the Emergency Vet: Prompt veterinary attention can be the difference between life and death, especially if large amounts of zante currants have been consumed. The veterinarian may conduct blood tests, administer fluids, or provide medications to support kidney function.

Preventing Zante Currant Ingestion

Prevention is always better than treatment. Here are some steps you can take to prevent accidental ingestion:

• Avoid Sharing Human Foods Containing Zante Currants: This includes foods like certain baked goods, trail mixes, and fruit salads.
• Educate Family and Friends: Make sure everyone in the household understands that zante currants, raisins, and grapes should not be given to dogs.
• Store Foods Properly: Keep foods containing zante currants out of reach of curious dogs, ideally in sealed containers.

Safe Alternatives to Zante Currants for Dogs

If you want to treat your dog to fruits, there are plenty of safe options that provide vitamins and enjoyment without the risks associated with zante currants. Consider these dog-friendly fruits:

• Apples (without seeds)
• Blueberries
• Strawberries
• Bananas

These alternatives can be a healthy and safe snack for your dog.

Final Thoughts: Keep Zante Currants Away from Your Dog

Feeding zante currants to dogs, whether as a snack or unintentionally through shared food, is risky.

Their toxic potential, especially the possibility of kidney failure, means it’s safest to avoid them altogether. By keeping zante currants and related foods out of reach and informing others about their risks, you can help ensure your dog stays healthy and safe.
