The ASPCA lists hibiscus (Hibiscus syriacus, also sold as rose of Sharon or rose of China) as non-toxic to dogs, cats, and horses. A dog that chews the flowers or leaves is not being poisoned, though eating a lot of any plant material can upset a stomach.

Why Hibiscus is safe
The ASPCA Animal Poison Control Center lists hibiscus as non-toxic to dogs, and lists rose of Sharon, the same species, as non-toxic as well. There is no toxic principle to act on, so chewing leaves or blooms is not a poisoning.
Make sure it is really hibiscus
The reassurance here is species-specific, and garden beds mix plants freely. Several genuinely toxic garden plants flower in the same showy way, and the site has pages for azalea, oleander, and hydrangea for that reason. If the identification is a guess rather than a certainty, treat the ingestion as unknown-plant and call your vet or poison control with a photo.
Signs to watch for
Usually none; after a large amount of plant material, mild vomiting or loose stool

A closer look at hibiscus
The ASPCA Animal Poison Control Center lists hibiscus as non-toxic to dogs, and lists rose of Sharon, the same species, as non-toxic as well. There is no toxic principle to act on, so chewing leaves or blooms is not a poisoning. The details below use the specific facts for this exposure, rather than treating it like every other plant question.
1. Start with the exact exposure
For a closely related comparison, read Hens and Chicks Echeveria. There is no toxic dose. Eating a large volume of any plant material can cause mechanical stomach upset, but that is a matter of bulk rather than of any compound in the plant.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Hibiscus Rose of Sharon. Yes. A dog that chewed hibiscus needs no treatment. Watch for mild stomach upset if a lot was eaten. Only if vomiting or diarrhea is repeated or persists beyond a day, or if you are not confident the plant was actually hibiscus.
3. If the details are uncertain
Follow the first 10 minutes guide. No emergency action is needed. Rinse your dog's mouth if you like, keep water available, and call your vet only if stomach upset continues.

The plant itself is not toxic, so brewed hibiscus tea is not a poisoning risk. There is no reason to offer it, though: water is what a dog needs, and blended teas can contain caffeine or other ingredients that are a different question entirely.
It is a persistent inconsistency across pet-safety sites. The ASPCA's own plant database lists both hibiscus and rose of Sharon (Hibiscus syriacus) as non-toxic to dogs, and that is the listing this page follows.
