Plain sparkling water is just water and carbon dioxide: no sugar, no caffeine, nothing toxic. The only real consideration is the gas. Flavored seltzers need a label check, and hard seltzer is an alcoholic drink.

Why Sparkling Water needs caution
Plain sparkling water is just water and carbon dioxide, with no sugar, no caffeine, and nothing toxic. The only real consideration is the gas, which can leave a dog burpy, bloated, or uncomfortable, particularly if they drink it fast. Flavored seltzers are where to slow down and read the label, since some carry sweeteners or citrus extracts, and hard seltzer is an alcoholic drink.
Signs to watch for
Burping, gas, bloated or gurgling belly, mild discomfort; with hard seltzer, wobbliness and drowsiness
What to do next
Nothing needed for plain sparkling water. Offer still water instead, and check the can if it was flavored.
Carbonation itself is harmless, but there is a specific picture that always warrants an immediate call.
1. Bloating that does not settle
Ordinary gas passes. A belly that is visibly distended and hard, with retching that brings nothing up and obvious distress, describes gastric dilatation and volvulus, which is an emergency in deep-chested breeds and is not caused by fizzy water but must never be waited out. Note that no established link exists between carbonated drinks and GDV; the point is simply that the sign outranks the cause. What dogs can and cannot drink, ranked honestly →
FAQ
How much Sparkling Water is dangerous?
Plain sparkling water has no toxic dose. A bowlful drunk quickly may cause noticeable bloating and discomfort, which usually passes. Hard seltzer is a different question, because that is alcohol.
Can I treat this at home?
Yes for plain sparkling water: switch to still water and let the gas settle.
When should I call the vet?
A hard seltzer or any alcohol, xylitol on a flavored can, or a distended, hard, or painful belly with unproductive retching. That last one is urgent regardless of cause.
