FDA puts a 16 fl oz energy drink at up to 328 mg of caffeine. For an 11 lb dog that clears the seizure threshold of 60 mg/kg. This is one of the few drinks where a single can puts a small dog in that range - call now.

More about this food
What separates energy drinks from other caffeinated beverages is the absolute load in one container. FDA cites 41 to 246 mg per 12 fl oz and 54 to 328 mg per 16 fl oz. The spread between products is wide, but the top end equals two or three cups of coffee in a single can.
Merck's canine thresholds are 20 mg/kg for vomiting and diarrhea, 40-50 mg/kg for cardiotoxicity, 60 mg/kg and above for seizures, with an oral LD50 of 100-200 mg/kg. Run the numbers: an 11 lb (5 kg) dog hits the seizure threshold at 300 mg, which one large can can exceed. A 7 lb (3 kg) dog gets there at 180 mg - a mid-size can. Even a 22 lb dog reaches it on two. Coffee takes several cups and cola takes several cans; an energy drink can do it with one.
Caffeine is not the only stimulant in the can. Guarana supplies additional caffeine beyond what the label may credit, alongside taurine, a large sugar load or artificial sweeteners, and high-dose niacin.
The non-liquid forms are worse. Energy shots in 2 oz bottles, caffeine pouches, caffeine tablets and pre-workout powder are small enough for a dog to swallow whole and far more concentrated. FDA warns that in humans, toxic effects such as seizures can follow rapid consumption of roughly 1,200 mg of pure caffeine - less than half a teaspoon. For a dog the equivalent is a fraction of that.
Signs generally start within one to two hours and can last up to 72 hours in severe cases: restlessness, hyperactivity, panting, vomiting, increased urination, tachycardia, arrhythmias, hypertension, hyperthermia, tremors, seizures and collapse.
Estimate what was drunk from what is left in the can, keep the container, and call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 now. Most cans print the caffeine content in milligrams; read that number to them and they can compute the dose per kilogram immediately. Do not induce vomiting at home.
Frequently asked questions
He only licked a little spilled energy drink.
A couple of licks is usually not an emergency, but caffeine content varies enormously between products. Check the milligrams on the can against your dog's weight, and call your vet if the dog is under 7 lb or you cannot judge the amount.
Is a sugar-free energy drink safer?
No. Only the sugar is gone; the caffeine is unchanged and some sugar-free versions carry more. Caffeine drives the risk, so use the same math. The sweeteners themselves do not cause hypoglycemia the way xylitol does.
My dog chewed a caffeine pouch / pre-workout scoop.
That is more urgent than a can. Powders, pouches, tablets and 2 oz energy shots are highly concentrated and easy to swallow whole. Bring the packaging and call your vet or the APCC at (888) 426-4435 immediately, even with no symptoms.
