Tea contains caffeine, and dogs are considerably more sensitive to it than people. Iced tea is the form most likely to deliver a real dose, because it is drunk cold and in volume from a knocked-over glass.

Why Iced Tea needs caution
Tea contains caffeine, a methylxanthine, the same drug family as the theobromine that makes chocolate dangerous, and dogs are considerably more sensitive to it than people. Iced tea is usually drunk cold and in volume, which makes it easy for a dog to get a real stimulant dose from a knocked-over glass. Sweet tea adds sugar, and diet versions need a xylitol check.
Signs to watch for
Restlessness, pacing, panting, racing heart, tremors, vomiting, increased urination, and in larger doses seizures
What to do next
Note roughly how much and whether it was caffeinated or sweetened, and call your vet. Caffeine effects come on within a couple of hours and small dogs need less than you would think.
The drug is the same as in coffee or chocolate. What changes is how much a dog can get in one go.
1. Cold, sweet, and easy to drink fast
A hot mug is rarely finished by a dog. A tall glass of sweet iced tea knocked onto the floor can be, and sweetened versions remove the bitterness that would otherwise put a dog off. That combination is why iced tea deserves its own page rather than a line on the caffeine one. Caffeine toxicity in dogs: the mechanism and the numbers →
FAQ
How much Iced Tea is dangerous?
A few laps of weak tea is usually low-risk for a big dog. A full glass in a small dog is a meaningful caffeine dose worth a call. Herbal and decaf teas are far lower risk, but check those for xylitol if they are sweetened.
Can I treat this at home?
A trace in a large dog, monitor. Anything more, or any small dog, needs advice, because caffeine has a genuine toxic threshold rather than just causing an upset stomach.
When should I call the vet?
Any real volume in a small dog, restlessness, tremors, a racing heart, or xylitol on the label.
