Caffeine. Most Americans live off of it! We start our days with our coffee or tea, enjoy caffeinated beverages with lunch, and have chocolate cake for dessert with dinner. While wonderful to the average human, this is a stimulant that should never be given to our furry friends. Caffeine is absorbed rapidly (within 30-60 minutes) after ingestion and can cause a variety of issues. Common physical signs can include vomiting, diarrhea, hyperactivity and increased general excitement, difficulty walking, seizures and muscle tremors. Abnormal heart rate and rhthm, increased drinking and urination, abnormal and difficulty breathing, and blue gums are also possible symptoms. These signs can be seen within 1-2 hours after caffeine has been eaten. Depending on the amount ingested relative to the size of your pet, caffeine ingestion can be very serious. It important to note that caffeine and chocolate are highly related, and the two together can present an even greater emergency.
