I am guessing that they love this cooler weather- they just seem to be so full of energy.  Both of them said hello to me several times this morning when I came in.  They were really talking a lot!  They trotted down the driveway and then they were practically running when we came back down the driveway.  I just realized though that I forgot to give them their milkbone.... so sorry Sib & Huski.  I did give Huski her medicine.
