ASPCA Animal Poison Control — People Foods to Avoid Feeding Your Pets · reviewed 2026-08-07 · confidence: high
Why
Colas and energy sodas contain caffeine — a methylxanthine that is genuinely toxic in quantity — plus a lot of sugar and carbonation that causes bloating. Diet versions may be sweetened with xylitol in some products, so check. Water is the only drink a dog needs.
Signs to watch for if your dog has eaten soda and soft drinks
Vomiting and diarrhea
Restlessness, hyperactivity or pacing
Panting, excessive thirst and urination
A fast or irregular heartbeat
Muscle tremors or seizures
Signs vary with the amount and with the individual pet, and some appear only after a day or more. Their absence does not mean your dog is in the clear — call rather than watch.
What to do now
Don't feed it. If your dog has already eaten some, call your vet or poison control with the amount and the timing and follow their advice.
Never induce vomiting and never give any medicine unless a vet tells you to. With some substances it causes more damage than the poison. This page tells you when to get help — it never tells you how to treat at home.
Safer alternatives for dogs
Plain baby carrots or carrot sticks
Plain cooked chicken breast — no skin, no bones, no seasoning
A few blueberries or a slice of apple with the core removed
Verdicts are transcribed from the cited veterinary sources, never inferred. Where a source establishes a finding for one species only, the other species is left null and the page says to ask your vet — a dog finding is never copied onto a cat.
