I don't know what type of shows (AKC, UKC, SV etc..) but as for me, I took my male to a well known show handler in the area the day before the show to practice gaiting and stuff. Thats it. I practiced stacking him and handling him since he was young, so he was used to being manipulated. Anyway, when he was about 1.5 years old, I entered him in an SV show just for fun, and he ended up doing great. I don't think its a waste of time, I gained ALOT of information and experience from that one long day at a dog show, and SV shows are so hard to find here, so I try and enter any show in the area that pops up.
I say go for it. You guys will gain some experience, and have fun. What's the harm?
