Yep, the sprinklers come out at 8:30 sharp.  We'd been outside for about 10 minutes and I heard them come on.  Jackson was in full terrior mode after something in the rock wall and I tried to get him to come in but he was totally ignoring me :)  I went inside and grabbed the treat bag, that didn't work either.  I didn't want to have to go get him b/c I really didn't want to get soaked.  Well, finally my sweet talking worked because he came.  Or more likely he got a whiff of the treats in my hand!  I hope you left the towel on the door for him.  I used it to wipe him off and his feet.   His feet weren't muddy at all but he was wet.   He didn't seem to care!
