If you’re panicking and Googling what to do if your dog eats chocolate—you’re not alone, and you’re right to act fast. Chocolate is toxic to dogs and can cause serious symptoms depending on the type and amount eaten. In this guide, we’ll walk you through the dangers of chocolate poisoning in dogs, what signs to watch for, how to respond quickly, and when it’s time to call the vet. Whether your dog snagged a single candy bar or chewed into baking chocolate, here’s what you need to know.
🚨 Why Chocolate Is Toxic to Dogs
Chocolate contains two ingredients that are dangerous for dogs:
Theobromine (main toxin)
Caffeine
Both affect the nervous system and heart, and dogs metabolize these substances much slower than humans.
⚠️ The darker the chocolate, the more toxic it is. Baking chocolate and dark chocolate contain far higher levels of theobromine than milk chocolate.
📏 How Much Chocolate Is Toxic?
Toxicity depends on:
Type of chocolate (baking, dark, milk, white)
Amount eaten
Your dog’s size and weight
Approximate toxicity thresholds:
| Type of Chocolate | Dangerous Amount for 10 lb Dog |
|---|---|
| Baking chocolate | ~0.5 oz (very toxic) |
| Dark chocolate | ~1 oz |
| Milk chocolate | ~2–3 oz |
| White chocolate | Minimal theobromine, but high fat/sugar |
🐶 Symptoms of Chocolate Toxicity in Dogs
Symptoms usually appear within 6–12 hours and may include:
Vomiting or diarrhea
Panting or restlessness
Increased heart rate
Muscle tremors or twitching
Excessive thirst or urination
Seizures (in severe cases)
