Hello. Thanks for writing in. Actually, she is most likely having a side effect from the Allegra D. Any antihistamine that has D behind it is not a good idea to give to dogs. They contain a decongestant, such as pseudoephedrine, which can be toxic to dogs and cause these symptoms. With any ingestion of these products, it is highly recommended to have them evaluated by a vet ASAP. It causes overstimulation of the nervous system, which can lead to seizures, high blood pressure, elevated heart rate and decrease blood flow to certain organs. We would usually treat them with sedatives, Valium, medications to slow heart rate and muscle relaxers. A prescription antihistamine called cyproheptadine can be used to block the effects. In rare cases, this toxicity can lead to blood clotting problems and excessive muscle breakdown. The metabolites from excessive muscle breakdown can damage the kidneys. i would have her seen by your nearest emergency vet tonight to avoid any potential serious complications. Please let me know if you have any other questions or concerns. Hope this helps.
