My 4 yr old GoldenDoodle Also has had 3 Seizures. 2 vets gave me the same advise as yours. Of course I searched the net on canine seizures. I had changed dry dog food brands . Since it has been several summer months , I think one of the ingredients in a name brand kibble may be our culprit. I went back to Cosco's Lamb and rice. Some breeds seem to be prone to seizures too. No meds here unless I have no options. Wishing your beautiful dog well and calm for you...hard to watch.
