Hi,
Thanks for the help
i was also wondering what class do i enter? I would really like to enter him for the Northern agility show,should I put him in the pre-competition class to get him used to going?
Thank you 
It's probably a good place to start, as the courses are likely to be more straight forward. For some dogs the whole experience of a show environment can be quite different/exciting. Charlie may want to say hello to the judge for example or just do his own thing, which the judges will half expect with newbie dogs.
Having said that looking at the NAWS schedule Class B is for Grades 1 & 2 so I'd expect a straight forward course.
Is Charlie OK with weaves & see-saw & do you need a toy in training?
Personally for a 1st show I'd be tempted to go for the pre-competition, you can watch the Grade 1/2 class & could always enter that the next time

Good Luck & have fun, but be warned, like Black Taz said, it can be addictive

I did the same thing with Harry last Winter, just to get him used to the atmosphere etc. & entered him at Grade 0
Similar to the indoor shows we did you get 2 goes over the same course at NAWS which I personally enjoy
