Oh I just love this type of question don't you? Basically: "Please explain why you so are so brilliant?" Much favoured, one notes, by career-minded Tory backbenchers at Prime Minister's Question Time.
So, yes of course Oz my friend, I would be delighted to give you the benefit of my hard won experience.
I have four important pieces of advice.
(I seem to recall that Oz lives in Italy, so to circumvent any language barrier I have also, in my own inimitable style, provided some self-explanatory - I hope - sketches to communicate my main points.)
Tip no. 1: Always make sure you have an experienced handler. One who knows her left from her right even under pressure, who can retain in her head the order of more than two obstacles at a time, and who can be guaranteed not to stumble over any of them herself…
Tip no. 2: Tolerant trainers are a must. The sort who understand that if the training field is adjacent to a field where horses are grazing, then every once in a while the urge to dash across to the fence to say hi to Dobbin cannot be resisted, even if it means crossing the path of the senior grade 'swotty collie' types as they prepare for high level competition.
Tip no. 3: Choose a club with pretty girl pups! Sometimes it can be a bit boring waiting for the other dogs to have their go round the set obstacle course, especially when they are even more erratic performers than oneself, and what better way to while away the time than to flirt with a fluffy wee bichon frisé (for example).
Tip no. 4: NEVER EVER POOP ON THE 'A' FRAME….
Oz, I wish you all the best in your Agility endeavours. I mean, how could you possibly go wrong now…?
