Can a West Highland White Terrier Eat Grapes?

Verdict: ❌ NO

Why Grapes Are Dangerous for Westies

Regardless of the breed, grapes and raisins are highly toxic to dogs, including West Highland White Terriers. While the exact toxin was long debated, recent research points to tartaric acid as the cause of toxicity.

Unlike some foods that are only toxic in large quantities, grapes can cause sudden, acute kidney failure in some dogs even in small amounts. Because Westies are small dogs, their threshold for toxicity is lower than that of larger breeds.

The Risks of Feeding Grapes to Your Dog

Feeding a grape or raisin to your Westie can lead to severe health complications. Watch for these danger signs:

• Acute Kidney Failure: The most severe risk, which can be fatal if not treated immediately.
• Gastrointestinal Distress: Vomiting, diarrhea, and loss of appetite.
• Lethargy: Unusual tiredness or weakness.
• Dehydration: Increased thirst or, conversely, a complete stop in urine production (a sign of kidney failure).

What to Do If Your Westie Ate a Grape

If your West Highland White Terrier has ingested a grape or raisin—whether it was one single grape or a handful—treat this as a medical emergency.

1. Call Your Veterinarian Immediately: Do not wait for symptoms to appear. Early intervention is key to saving the kidneys.
2. Contact Pet Poison Control: If your vet is unavailable, call a pet poison hotline.
3. Do Not Induce Vomiting unless specifically instructed to do so by a professional.
4. Provide Water: Ensure they have access to fresh water to help flush the system, but prioritize the vet visit.
