My son has a Jack Russell Terrier. A week after having her spayed, she began to have seizures. Our vet did blood work and everything came out fine. They said it is probably epilepsy. Is it possible that something changed after the surgery? Can people food that contains high salt contents cause seizures? The other thing that is odd is she only has the seizures at night when she is asleep.
I do not believe this had anything to do with the surgery or salt in the food. Your vet is probably correct. vetcare
