Burls, I have really been light on training as of late due to the hot weather. For example, the other day it was about 92 with a dewpoint of 74! My shorthair, and as anyone who has/owned shorthairs will attest, is ALWAYS ready to go chase something. Wish I could tap that energy!
Anyway, I let him out and started our "funtime" session. This is where I will simply toss a tennis ball for 10-15 minutes without any commands to let him burn off his initial "stupid" energy, and then I concentrate on commands after that.
How hot was it? 7 tosses, he zips by me with ball in mouth, heads straight for the kennel, immerses his entire face into his water bowl for 30 seconds, comes up slobbering and spitting, and heads indoors into the garage part of the kennel. Not a peep the rest of the night!
Work you dog as much as you can, but another important thing to remember is your conditioning too. Too many guys will wait until their first hunt of the season to do any walking whatsoever, and then they complain for weeks about how sore and tired they are!
Keep it up!
