i know there's two schools of thought on poo: one is that all poo is good
(that would be me)

In just a few words :-)

Cow manure is considered safe and excellent for compost or direct in
the garden but most dogs receive medications periodically to rid them
of parasites and the medications can also kill compost worms. So first
off there is a withholding period when dog poo can't be added to the
worm farm.

but you can add the poo later after it's sat for a while, if you are
concerned :-) also, medications have changed - this may no longer be true
in all cases. (well, i know horse medications have changed - one would
need to find out concerning dog medication specifically).

Dog dewormer has the active ingredient called fenbendazole. Compost worms
are called Eisenia fetida. If you do a google or vivisimo search on these
two search criteria, I'd be most interested if you can manage to find
anything to worry about. I couldn't.

I had no luck finding anything of a scientific nature that suggested there
was any chance of the worm farm worms being killed by any of the common
vermicides applied at the recommended dosage rates.

The only really negative info I found related to Ivomectin and in that case,
it seems that you'd need to overdose the animal (not a dog) to the point of
death with Ivomectin (which isn't a dog dewormer) to have any affect on soil
earthworms at all.
