My dogs are constant companions while I work each day. They seem to know time as they watch and anticipate my schedule. It amazes me that they are so accurate, within 10 minutes. Every day at 2:30pm, I bundle myself up and take them for the 1.5 km walk to the school bus stop to pick up my daughter. Every day at 2:20pm they start following me around wagging tails and barking. I was curious to see how they would handle the time change (daylight savings). It only took them 2 days to adjust to the new schedule. Amazing.
