Measured for agility

Can anyone tell me how I get this done, I have been told it can be done at agility shows but how do you know which ones. Is there anywhere else you can take your dog to get them measured rather than trying to get to a show.

The shows are the main where you can get your dog measured.
If you are with a club sometimes they will get measures in.
Other wise get in touch with the Kennel club and they will tell you the nearest place/show that you can go to.
Once your dog has been measured you will have to get him/her remeasured again after 12months because you have to have 2 measures . hope this helps you.
