Why coffee is toxic to dogs
Caffeine, a methylxanthine like the theobromine in chocolate. It overstimulates the nervous system and heart, and dogs are more sensitive to it than people. Pet Poison Helpline puts the level where poisoning can start at about 9 mg per lb of body weight.
Signs to watch for after she eats coffee
Restlessness, hyperactivity, pacing or vocalizing, panting, vomiting, diarrhea, extra thirst and urination, a racing or irregular heartbeat, high blood pressure, overheating, tremors, seizures and collapse. Signs can start within 30 minutes but usually show in 1 to 2 hours, and can last several days.
