My Dog Ate a Coffee Bean. Will They Be Okay? 

As a pet owner, you take the right steps to ensure your pet has a safe and healthy life. But sometimes it doesn’t work out that way, like when your furry friend decides to eat unexpected items, such as a coffee bean. Coffee beans contain caffeine, a stimulant that is highly toxic to dogs. Therefore, if your dog ingests coffee beans, it is important to take the situation seriously and seek immediate veterinary assistance. Read below to learn about the potential dangers of caffeine poisoning in dogs, the symptoms to look out for, and steps to ensure your furry friend’s well-being.  

A Bitter Brew: How Coffee Beans Can Affect Dogs 

Dogs can experience serious poisoning if they ingest coffee beans due to the high concentration of caffeine they contain. Unlike a cup of coffee, which has a diluted amount of caffeine, coffee beans have a much higher concentration. While one or two coffee beans are unlikely to cause a problem, when dogs consume many coffee beans, the caffeine affects their gastrointestinal, cardiovascular, and nervous systems. It can cause an increase in blood pressure, cardiac arrhythmias, loss of muscle control, tremors, and even seizures. It’s worth noting that smaller dogs are even more susceptible to the harmful effects of caffeine. Therefore, it’s crucial to keep coffee beans and other caffeine-containing products out of reach of dogs to prevent accidental ingestion and potential poisoning. 

Clinical Signs of Caffeine Poisoning 

Your dog can experience caffeine poisoning if they eat coffee beans. Signs of poisoning typically appear within 1 to 2 hours after ingestion. Common symptoms include: 

  • Vomiting 
  • Diarrhea 
  • Tremors 
  • Seizures 
  • Increased heart rate 
  • Elevated blood pressure 
  • Restlessness 
  • Agitation 
  • Heart arrhythmia 


If your dog has eaten a coffee bean and is showing symptoms of poisoning, contact your veterinarian and Pet Poison Helpline at (855) 764-7661 for medical help. Bring your dog to the veterinary clinic, so they can receive treatment. If ingestion occurred recently, your veterinarian will induce vomiting and administer activated charcoal to bind the toxins. Specific medications may be needed to stabilize the circulatory and central nervous systems. If the poisoning is severe, your pup may need ongoing supportive care and hospitalization for monitoring. While you may need that boost of caffeine in the morning, make sure you securely put away your coffee beans when you’re not using them so your dog cannot eat them. When you use them keep an eye out for your pup to ensure that they are not trying to sneak a bean. If you have further questions or concerns, make sure to give Pet Poison Helpline a call today!
