Where are you doing it? And who with?
Coco and I have done the first 2 with Pam (the founder of TD) and it was fab. Coco had a great time, she picked it up very fast, was focussed and loved doing the searches.
Brilliant fun - it was a long day and exhausting for us both though
Lots of things you can learn to use back at home - we often do searches out on walks or around the garden.
No real tips, apart from have a great time. Only thing is, there is quite a bit of time waiting for your turn, so a mat or rug for your dog to settle on is a good idea. Coco wanted to shout advice to the dogs who were having their go - she was soooo excited she could hardly wait to have her turn
