🚫 No eating: Grape Juice (Vitis vinifera)

🧪 Toxic Mechanism

• The mechanism of grape toxicity in dogs is still partially unknown.
• Suspected cause: water‑soluble toxic components that damage the renal tubules (kidneys).

---

⚠️ Extreme Concentration Risk

Grape juice is more concentrated than fresh fruit → the toxin strength is higher.

• Even a few grapes or a few bites of grape juice have been reported to cause acute renal failure in small dogs (e.g., Yorkshire Terrier).

Symptoms include:

• Vomiting
• Anorexia (loss of appetite)
• Progresses to anuria (no urine production)

---

🛑 Complete Prohibition

Completely forbidden to eat.
No amount of grape juice is safe for any dog.

---

🆘 Emergency Treatment (if ingestion occurs)

1. Induce vomiting immediately (if within 2 hours and asymptomatic).
2. Administer activated charcoal to absorb remaining toxins.
3. IV fluid therapy for at least 48 hours (to protect kidneys).
4. Monitor creatinine, phosphorus, and calcium ions at:
   • 48 hours
   • 72 hours

📈 Prognosis

• Early treatment → good prognosis.
• Delayed treatment → death.

This warning must be placed at the highest level of urgency.

---

🧴 Prevention

• Keep all grape‑based products (juice, fresh grapes, raisins, currants) completely out of your dog’s reach.
• Remember: concentrated juice is even more dangerous than whole fruit.
