Aww poor girl. Hope she doesn't have any more seizures.

Is it possible that there could be some environmental stimuli causing the seiuzures? Did you give her any parasite control medication? Ivermectin can cause alot of problems, including seizures, in herding breeds, especially collies. Vaccinations can also cause seizures -- you might want to ask your vet to give her vaccinations at longer intervals than is usual to give her time to recover from the last one. You should also get her blood tested for hypothyroidism. There may also be mold in the carpets or something, or possibly she ate something bad and the toxins are still in her body? What kind of food do you feed her?
