Is it true small dogs are more prone to develop epilepsy? - what is epilepsy more condition_symptoms

I have a Jack Russell, which began recently, with severe cramps. the vet said this could be caused by a serious medical problem (Brian tumor or liver disease may be) or with epilepsy, being developed mostly in small breeds. Never heard of it, and he had several small dogs without this problem before. No one has the development of epilepsy, for no apparent reason often heard in small breeds?
