Frequently Asked Questions
Why is chocolate toxic to dogs?
Chocolate contains theobromine and caffeine, both of which are methylxanthines. While humans metabolize these easily, dogs process them much more slowly, leading to toxic buildup in their systems.
What are the symptoms of chocolate poisoning?
Symptoms usually appear within 6 to 12 hours and can include extreme thirst, diarrhea, pacing, shaking, and seizures.
What should I do if the calculator says "Emergency"?
Call your veterinarian or the nearest animal emergency hospital immediately. Do not wait for symptoms to appear.
