We took our dog , years ago, to a show here called "parts-a-rama". It is in july I think and all I remember is how HOT it was and how miserable the dog was and therefore us.
Think about it....do you really want to drag your pet through miles of walking in and out of parts displays etc?
Not to mention the evil eye you will get from car owners when your pet gets just a little too close or gets frisky around their car?
There are people who have their (big) dogs with them at local cruises and frankly I dont think its appropriate.
The pets arent enjoying walking on hot asphalt or gravel all day.
