Frequently Asked Questions
Why is chocolate toxic to dogs?
Dogs metabolize theobromine much slower than humans. While we can process it quickly, dogs can't, leading to toxic buildup that affects their heart and nervous system.
How much chocolate can kill a dog?
Approximately 100-200 mg of theobromine per kg of body weight can be lethal. For a 20 lb dog, this is about 2 oz of baking chocolate or 10 oz of milk chocolate.
What should I do if my dog ate chocolate?
Note the type and amount of chocolate, your dog's weight, and when it was eaten. Call your vet or ASPCA Poison Control (888-426-4435) immediately.
Can a small amount of chocolate harm my dog?
Small amounts of milk chocolate usually cause only mild stomach upset in larger dogs. However, dark chocolate and baking chocolate are dangerous even in small amounts.
How long does chocolate poisoning take to show?
Symptoms typically appear within 6-12 hours and can last up to 72 hours. Early symptoms include vomiting, diarrhea, and restlessness.
Is white chocolate safe for dogs?
White chocolate contains minimal theobromine and is unlikely to cause toxicity, but it's high in fat and sugar which can cause other problems like pancreatitis.
