OMG! Bwaa, haa, haa, haa!!!!!!
That picture is just WAY too hysterical, thank you Allison Finch I really needed a good hard belly laugh!
Okay, back on topic...
I also find that starting with a clean as possible horse helps as well, does not dull your blades as quickly.
Oh, and if you can clip about 2 weeks before you are going to show, that gives time for the hair to "blend".
Good luck and let us know how it goes for you!
