When some people hear "exercise" they might think a 30 minute walk will suffice. With a younger sheltie, they usually need their exercise to be off leash full out running. Walking doesn't do much for their energy level. (Just wanted to make sure they understand "good exercise") Also, nothing can replace the need for mental exercise as well. They are very different mentally than Havanese or Spaniels. They really enjoy working things out in their head during training sessions and such.
This is very interesting. What kinds of things would be considered mental exercise?
