Project Description
Caffeine, a methylxanthine, can cause toxicosis when ingested by pets. Dogs are the most frequently intoxicated species due to their indiscriminate eating habits. Any age or breed of dog can be affected. A similar clinical course can also occur in cats if ingestion occurs.
It is important to note that caffeine is often found in products containing chocolate (another common pet toxin).
Signs and symptoms of toxicity: vomiting, diarrhea, panting, excessive thirst and urination, abnormal heart rhythm, tremors, seizures. These signs usually occur within 1-2 hours of ingestion.
Toxic Consumption:
In dogs, 140 mg/kg (63 mg/lb) can be toxic. For cats that value ranges from 80-150 mg/kg (36 – 68 mg/lb).
