Hey, I hate to rain on your parade, that was a terribly cute video, but I decided to Google dogs and hibiscus and came up with a hit on an AASPCA site that you might want to check out.

It was just on a forum section, so I'm not sure about its validity but thought I"d pass it on.

Is it safe for dogs to be around a hibiscus tree? I didn't see this tree on the poisonous list, but I've heard it's not good for dogs if they ingest a hibiscus leaf or flower. Is this true?

It is true that the hibiscus species can be potentially toxic, Christa. These trees can possibly cause gastrointestinal upset that could become significant and could lead to dehydration. Drooling, loss of appetite and depression can also occur. Based on this information, we would advise you to keep hibiscus out of the reach of your pets.

Here's the link to the discussion, but that's all it says.
