My dog had 3 seizures yesterday?

After leaving her and my other dog home for the weekend, the day after I came home Leah had three seizures over the course of a few hours. She's a very young puppy, 2 months maximum, and weighs under 20 pounds. We don't know if this is a recurring event, we just caught it yesterday. We're curious though: could borax powder have been the cause? I poured a LOT of the powder around the edges of the porch to keep ants away from the food, and there was a LOT in close proximity to her food dish. She also seems to be a lot better now; her energy is back up and she's biting the crap out of my flip flops like normal. Help?
