Idiopathic seizure activity? At age 14 she may be just failing in general, you may see some confusion and cognitive changes also.
I have a 15 year old small breed and he’s not the same dog he was even a couple of years ago. He had some mild seizure activity a few years ago after his rabies shot, so the vet agreed with me, no more vaccinations for him.
Have you tried soaking the kibble and adding a spoonful of wet food or homemade plain chicken broth.
