Michelle!Here are the signs,maybe it makes it easier to understand them!
I think those are pretty easy ones?
13-14:The dog is in heel position ,you stop and call your dog on the front,you can step back a couple of steps if needed,then call your dog back in heel position on R or L side and keep walking towards to the next sign.
15-16:Same as above the difference is when the dog finished the exercise,he has to sit before you go to the next station.
29:You should know that!!!
