Dear Jon,
Don't worry! Those ant baits are not toxic to dogs. Even a small dog would have to eat at least ten before she would even get sick.
For the most part these ant traps are not toxic to dogs. If the dog ingests large numbers of them, then there might be more cause to worry, but just one or two should not contain enough poison to do anything at all. However, if your dog ingests the plastic portion, it can cause an intestinal obstruction . You can read about these and they symptoms of them on this website. http://www.petplace.com/dogs/gastric-stomach-foreign-body-in-dogs/page1.aspx

As long as she did not eat the packaging your girl will be fine
Warmest best wishes,
