My toughest experience probably doesn't even make the Top 10 list of the more seasoned dog people. Last June at the Tulsa Retriever HT Saturday morning 60 dog master. I'm test dog. Everything is set-up at 7:30, but clouds start to appear darker about 8. They call for test dog. Land Triple with a double blin w/ honor. Stoney picks up triple, runs first blind and we start to run the 2nd when a sprinkle starts. Total time took maybe 5 minutes to run test. Judge goes "any questions?, ok dog to the line". Wind picks up rain starts pouring as I'm on the honor. Dog #1 runs the test, but by the time its done and bird techs come in everyone is soaked. We got probably 2-2 1/2 inches of rain in the next hour and the land triple becomes land/water combo series as we were running over some terraces. Terraces were holding 18-24 inches of water. If a smaller dog hit it in just the right spot it would actually have to swim. Re-birding required waders or hip boots. Rest of the weather was fine for the weekend but soaked and water logged all the birds before any were thrown. Couldn't really dry them off all weekend.
