We haven't been doing a lot of walks because it was just too hot. But now it's starting to cool down so we are going to get back into the habit of doing at least one walk a day. Unfortunately I have to drive them both to a park because I don't like walking them around our neighborhood because several people own very ill-behaved large dogs and that worries me with my two little ones. So on days we don't make it out for a walk we do a LOT of fetch down the hall. Tuffy fetches the ball and Pixie runs after Tuffy and we do that until they get tired of it.. which is usually about 1-2 hours laterl.
