Are Coffee Beans Bad For Dogs?Coffee may be a vital part of our day, but are coffee beans bad for dogs? But what if these two loves cross paths? Well the chemical in coffee that makes us love it is caffeine, and caffeine can cause toxicity to humans in extremely high doses, so imagine what it could do to our much smaller counter parts, our dogs.


Caffeine is a drug, specifically a stimulant drug. Stimulants increase the speed in which messages are sent between our brain and our bodies. This is why it makes us feel more awake when we gulp down that first cup of joe in the mornings. Other stimulants include amphetamines and nicotine.

The odd slurp of highly dilute coffee for a dog is no harm done, concentrated products such as coffee beans or grounds on the other hand have the potential to cause severe toxicity. The effects of caffeine are greatly dependent on size, weight and health, meaning, a smaller dog may be much more effected than a larger dog, however, dogs tend to be much more susceptible to the effects than humans. Symptoms of caffeine toxicity can last up to 12 hours, and sometimes more depending on how much was actually ingested.

What to Look Out For?

It can take just 30 minutes up to a hour for full toxicity to take effect. A pet who has ingested caffeine through coffee beans or other means may show varied sighs including increased blood pressure, heart rate and temperature, vomiting, hyperactivity and restlessness, shaking and eventually seizures and collapse. Worst case scenario may even cause death. It can take just 14 milligrams of caffeine per pound of body weight to cause symptoms in dogs and levels as high as 23 milligrams per pound of body weight can cause cardiotoxicity (Pet MD, 2020)
