Our 12 year old Ridgeback Cross started having seizure last December. Took her to vet and they prescribed Levetriacetam. Seemed like it worked but had to increase dosage to 3 times a day 750mg at a time. Has had 2 in the last two days. Anybody else had something like this with your pet. Sure don't want to lose her but can't stand to see her go though this.
