What Information to Have Ready
- Pet Details: Species, breed, age, weight, pre-existing conditions
- Toxic Substance: Exact name, brand, ingredients if known
- Quantity Consumed: Estimate how much was eaten
- Time of Ingestion: When it happened (as exact as possible)
- Current Symptoms: Vomiting, diarrhea, lethargy, etc.
DO NOT INDUCE VOMITING Unless Instructed
Never induce vomiting without professional guidance. Some substances can cause more damage coming back up (like corrosive materials or petroleum products). Only induce vomiting if specifically instructed by a veterinarian or poison control expert.
Most Dangerous Foods for Pets
These foods cause the most severe and frequent poisonings in pets. Even small amounts can be fatal.
Chocolate & Caffeine SEVERE
Contains theobromine and caffeine, which pets cannot metabolize effectively. Toxicity depends on type and amount: Dark chocolate & baking chocolate are most dangerous.
Symptoms & Toxic Amounts
- Mild: 20mg/kg (milk chocolate)
- Severe: 40-50mg/kg (dark chocolate)
- Fatal: 100-200mg/kg (baking chocolate)
- Symptoms: Vomiting, diarrhea, hyperactivity, seizures, death
Xylitol (Artificial Sweetener) LIFE-THREATENING
Found in sugar-free gum, candy, baked goods, peanut butter, and some medications. Causes rapid insulin release leading to hypoglycemia (low blood sugar) and liver failure.
Symptoms & Toxic Amounts
- Toxic dose: 0.1g/kg (100mg per kg of body weight)
- 1 piece of gum can poison a 10kg (22lb) dog
- Symptoms: Weakness, collapse, seizures, liver failure
- Onset: 10-60 minutes after ingestion
Grapes & Raisins SEVERE
The toxic substance is unknown, but even small amounts can cause kidney failure in dogs. Raisins are more concentrated and therefore more dangerous. There's no safe amount.
Symptoms & Toxic Amounts
- Toxic dose varies (idiosyncratic)
- Some dogs sick from 1-2 grapes/raisins
- Symptoms: Vomiting, lethargy, abdominal pain, kidney failure
- Kidney damage may be irreversible
Chocolate Toxicity Calculator
Use this rough guide to assess chocolate toxicity risk:
- White Chocolate: Minimal risk (very little theobromine)
- Milk Chocolate: Mild toxicity at 1oz per 1lb of body weight
- Dark Chocolate (60% cocoa): Toxic at 0.3oz per 1lb of body weight
- Baking Chocolate: Highly toxic at 0.1oz per 1lb of body weight
- Cocoa Powder: Most dangerous - toxic at 0.02oz per 1lb
Quick Calculation
For a 20lb (9kg) dog:
• Milk chocolate: Toxic at 20oz (entire large bar)
• Dark chocolate: Toxic at 6oz (half a bar)
• Baking chocolate: Toxic at 2oz (2 squares)
When in doubt, call your vet immediately!
Xylitol: The Hidden Danger
Xylitol is increasingly common in "sugar-free" products. Check these items carefully:
- Gum & Mints: Most sugar-free varieties contain xylitol
- Peanut Butter: Some "natural" brands use xylitol as sweetener
- Baked Goods: Sugar-free cookies, cakes, muffins
- Medications: Some chewable vitamins and supplements
- Oral Care Products: Toothpaste, mouthwash (use pet-specific products)

| Food Item | Toxic Component | Primary Species Affected | Common Symptoms |

| Alcohol | Ethanol | All Pets | Depression, vomiting, difficulty breathing, coma |
| Macadamia Nuts | Unknown toxin | Dogs | Weakness, vomiting, tremors, hyperthermia |
| Avocado | Persin | Birds, Rabbits, Horses | Difficulty breathing, fluid accumulation |
