The more I hear about Lady, the more convinced I am that Duncan must be a flat-coated!! I have never, ever seen him run out of energy...We go to the park morning and night and he runs around the entire time!! The other night I took my friend's dog with us and after about 45 minutes both he and I were sitting down and Duncan was jsut running in circles around us! BUT in the house, if I want to lie down and nap or just be mellow, he'll do the same.
Also, he eats everything!! I love brussel sprouts ( I know everyone else hates them...!)I gave one to Duncan and after a few seconds and spitting it out once, he ate it!! I couldn't believe it!
