Indie does this sometimes too.
Someone gave me the advice that the better quality dog food you feed, the less waste there is, meaning their poo doesn't appear so appetising for them, for want of a better word :oops:
Since we changed him from Bakers to Burns/Naturediet, he's been doing it much less often, so I feel there is some truth to the diet link.
I have also heard of people adding stuff to their food, to help prevent it, but I can't recall what. I'm sure you'll get some great advice here though.
