Can Dogs Drink Coffee?

Caffeine belongs to a class of compounds called methylxanthines, which also includes theobromine (found in chocolate). Dogs metabolize these substances much more slowly than humans, allowing them to build up to toxic levels in their system. Caffeine acts as a stimulant, over-activating the central nervous system and heart.

• Brewed Coffee: Even a few sips of brewed coffee can be harmful to a small dog.
• Coffee Grounds: Used or unused coffee grounds are particularly dangerous as they contain highly concentrated amounts of caffeine.
• Coffee Beans: Whole or ground coffee beans also pose a significant risk.
• Coffee-Flavored Products: Any food or drink containing coffee extract or flavoring (e.g., ice cream, candy, energy drinks) should be strictly avoided.

• Symptoms of caffeine poisoning can appear within 30 minutes to an hour after ingestion and can be severe. Seek veterinary help immediately if you notice:
• Hyperactivity, restlessness, or agitation
• Vomiting and diarrhea
• Increased heart rate and panting
• Muscle tremors
• Elevated body temperature
• Seizures
• Collapse
• In severe cases, caffeine poisoning can lead to cardiac arrest and death.

This is a veterinary emergency. Contact your vet or an animal poison control center immediately. Do not wait for symptoms to appear. Be prepared to tell them how much coffee your dog consumed and your dog's approximate weight. Time is critical for successful treatment.

Coffee, like black tea and other caffeinated products, is highly toxic to dogs. Ensure all coffee products, including beans, grounds, and brewed coffee, are kept securely out of your dog's reach at all times.
