Frosty, I agree with that statement.

First of all there is no way in the world any human or animal athlete is getting into its best physical shape in 8 weeks, that is ridiculous.

Trying to achieve "best physical shape" would have to be a process started from the beginning. Jack has stated before to feed optimaly, and even with that unless you are conditioning the animals body optimaly all of the time, you still would have a hard time finding that dogs "best physical shape".

There are just so many reasons one can not achieve this, one of the main obstacles other than time would be injury.
