£10.74 a month for a 3-y-o working cocker with More Than. Not the greatest cover (i.e. not a lifetime plan), but our vet has very limited facilities so we're unlikely to ever rack up a gigantic bill (even our old springer's final one was only just over £1,000 and she was in there for a week having a battery of different tests.)
Once she gets to about 6 or 7 I'll start self-insuring, though as for the horses, I'll retain cover for third-party liability, which is something I would recommend to anyone else on the thread self-insuring - it's not expensive and if a dog escapes or gets loose, gets onto the road and causes a car accident it could cost a fortune.
