My breeders told me to always dress professionally as it was a sign of respect to the judge. A nice tan suit always looks good. The objective for your dress is to compliment the dog and to make you look invisible
Its all about the dog.
Heehee...theres a thread around here about what not to wear to a dog show. As long as you dont go into the ring looking like them you will be fine
I bait with beef jerkey and keep it in my mouth. Pockets are not as prevalent as one would like them so keeping it in my mouth is usually the safest bet. I dont use liver to bait because there is no way that is going in my mouth lol
Also, someone once told me that one should not use the dogs name while in the ring. Not sure how true this is so maybe someone else can chime in but it is easy enough just to call the dog "puppy" so I just do that.
