Hi womblewoo,
I'm toilet training a pup at the moment too (not much fun in this weather LOL).
I don't take him out hourly - but regularly when he wakes from a nap, after meals, immediately after playing (mid-way if he's going at it hammer and tongs

) etc so no definite time spans in between, more a judgement call and watching in between for any tell tale sniffing, circling or strange tail carriage LOL.
Personally I've always found this the easiest way to go about things as the puppy is pretty much ready to go immediately when taken out rather than mis-timing things and maybe being distracted by playing in the garden etc rather than making the connection that it's toilet time instead :)
As for food treats on performance I don't treat - just verbal praise (squeaky. embarassing voice etc :-D ) as IME they "go" so often at this stage that even the strongest metabolism would fail under the strain!
HTH, Teri :)
