If your dog is experiencing either mild or severe seizures, there is
help for both of you. Work with a veterinary professional with whom
you feel a good rapport, and educate yourself on seizures and their
treatment. Follow the vet's instructions, never change medication or
dosages without a consultation, be observant, monitor serum levels as
recommended, have patience and be willing to try another form of
treatment if that seems indicated. Above all, if your breed club
sponsors a health registry or research project on seizures or epilepsy
in your breed, participate fully in it. New research on epilepsy is
being done each year in an effort to determine how it's inherited and
ultimately, to design a test that will allow breeders to select
against this health defect.
