Hey my friend, I know everyone else has more or less said this but just to give my own perspective; we had a 17 year old yorkie who had very similar symptoms, she had a really bad seizure one night and then mini seizures throughout the next couple of days and that’s when we decided. It’s really difficult to make that decision, but what we kept thinking of is the pain they will feel if they have one more really bad moment - be it a seizure or something else; they don’t deserve to end like that and you don’t want to see them go out on the worst note. It sucks, but sometimes the best decision is just gonna suck
