It's great to see a 'non smart' breed. And 'get them young enough' - got her at 8 months! I don't think that is incredibly young. I'm sending this to all my cav friends now!
Dumb mutt lol. You don't "get" a dog intelligence - it has it already - it's whether you're willing to channel it or not that's the big issue as far as I'm concerned. Still that dog can do some pretty interesting things.
