My first Leo had epileptic fits that were tied to hormonal changes.
Started out of a blue when she was about 4 years old and never had one after being spayed.
Somebody had a look at her lines(who had an epileptic Leo too) and in our case it seems it was genetic...
The lady had collected pedigrees of quite a few epilectic Leos and all had common names in the pedigree but then most Leos do so not sure how genetic it really was!
With a Lurcher maybe one parent was BC, don't they have some epileptic lines?
30 minutes is very long time to fit :( I can see why the vet thought PTS is the kindest option even tho epilepsy can often be controlled by drugs.
