Also worth a mention too is to hot wash all bedding; human and dog! :)
In my part of the world flea infestation seems to be a very common ocurrence, mainly due to heat and humidity.
I've been lucky so far and only ever found a couple of adult fleas on one of my dogs after he'd been running in the garden.
I didn't know whether he'd picked them up from the grass or had them prior.
So as I'm a paranoid Mum about bugs and beasties (since living in Qld!!) I had all the dogs bedding into the wash, sprayed beds and carpetted areas of the house with a flea spray, and gave both dogs a capstar tablet (only one, as they'd already been spot-on treated).
Fingers crossed, touch wood and all that superstitious stuff, we haven't had any since.
Neither do we have roaming cats (illegal in this state!), so they're one less flea carrier to worry about! Just got the possums and 'roos to think of!
