I know what you're saying Rosemary, but Padge has asked a reasonable question and deserves a reasonable answer, hopefully several!
Padge, have a look at the advice on the ISDS site (which will include the appropriate health checks and information about registration) and see if you can pre-sell the litter (to working homes please!)
Do you know of an appropriate stud dog you would use? If not, it might be worth approaching your nearest traillist / breeder - up my way this would be Derek Scrimgeour (Killibrae Sheepdogs.) If they were happy to use one of their dogs with your bitch, they'd maybe help with marketing the litter too - Killibrae Sheepdogs has a very active Facebook page which often has info about pups bred using a Killibrae sire.
It's especially important with working collies to be sure you can find good working homes. Not all the pups will work, perhaps (not all take to it), but a collie that has the instincts will struggle to fit into a conventional pet home - many of them end up with the rescue charities as problem dogs.
