Another thing, he need to learn to groom his golden - how to bathe, blow dry and trim. A Junior Handler is the one that is responsible for the grooming of their dog in the ring. If you can get into a seminar to learn grooming a golden or if your breeder can give you lessons. I have been to many and am still learning. My breeder lets my daughter practice on her retired dogs too.
My breeder bathes all of hers once a week. During a show weekend everyday.
I try to do my show dogs every 10 days, but that does not always happen. Show weekends, everyday, or at least hose them down and blow dry them every day after the initial bath - morning of the show, or night before.
