>We took him down to the vets to get blood taken ,but vet said it prob wont show up anything as you can not test for this
No epilepsy will not show up on a blood test.
I find it quite strange that the vet has put forward the diagnosis of epilepsy after 1 seizure. This is generally a diagnosis made after other things have been ruled out and after several seizures. Seizures can be caused by many different things, including a bad infection that is making the dog very poorly.
> i have put him on aloe vera gel and calm dowm as am unsure as to get meds from the vet as it can damage his liver i was told .
What has the vet prescribed?
Often the respone/lack of respone to prescribed medication can help the vets with a diagnosis. What did the vet say to you about refusing a prescription?
It can be dangerous to give the dog things the vet is unaware of. There is no way I would be giving my dog any 'calm down' remedy or any other treatment I had sourced myself if he had a seizure, unless of course the vet OK'd it first.
