Why Pedialyte needs caution
Unflavored Pedialyte, diluted, is widely tolerated by dogs in small amounts and is sometimes suggested by vets, but there are no veterinary studies on using it in dogs, so its effectiveness is not established and it should not be the first thing you reach for. Flavored and zero-sugar versions are the concern, since those can carry sweeteners including xylitol, which is dangerous to dogs at any amount. A dog dehydrated enough to need electrolytes usually needs a vet, not a supermarket drink.
Signs to watch for
Usually none in small amounts; loose stool or vomiting if given too much; with a xylitol-containing version, weakness, wobbliness, seizures
What to do next
Read the label for xylitol, and if your dog is dehydrated enough that you are reaching for Pedialyte, call your vet rather than trying to fix it at home.
This is the drink owners reach for when a dog is already unwell, which is exactly when guessing is least useful.
1. Oral fluids only work if they stay down
A dog losing fluid to repeated vomiting or diarrhea cannot be rehydrated by mouth, and time spent trying is time the dog spends getting worse. Tacky gums, sunken eyes, or lethargy mean the fluid deficit needs replacing under the skin or intravenously. Puppies reach that point fastest.

FAQ
How much Pedialyte is dangerous?
Small amounts of unflavored Pedialyte diluted roughly 1:1 with water are generally tolerated. There is no established dose for dogs because the research does not exist, so this is a stopgap, not a treatment. Any xylitol-sweetened version is unsafe at any amount.
Can I treat this at home?
Only as a short bridge for a mildly off-color dog who is still drinking. Ongoing vomiting or diarrhea means fluids the dog cannot keep down by mouth, which needs a clinic.
When should I call the vet?
Any xylitol on the label, a dog who will not drink or keeps vomiting, sunken eyes or tacky gums, or a puppy, because puppies dehydrate fast.
