A call to the vet when in doubt is always best. Online assistance is OK in some situations but when you are dealing with a possible poisoning, trauma, or any event you are unsure of call the vet or get in the car and head there ASAP. I'm glad to got her there as soon as she vomited. I hope she stays well for you.
Gosh, all we have to deal with are coyotes, hawks, owls, and bears. Toads are a less obvious threat but that can make them all the more dangerous I guess.
