That is about 5 times the dose typically prescribed for a dog her size. There can be some serious side effects such as increased heart rate, high blood pressure, excitability, panting and even seizure like symptoms. The best thing to do would be to get her to vomit using about 3 tablespoons of peroxide that can be repeated in 10 minutes. If possible take her to an emergency clinic so that medications can be given to prevent absorption of the pill. Since it has been about an hour, the vomiting may not be effective at removing the drug. If she starts to develop symptoms then medications can be given to counteract them while the drug gets out of her system. If you have more questions please let me know.
