the goat that i think has them isnt a milker...well she is, just not at the moment if that makes sense.
will go down the ivermectin route me thinks....tho vet says he will do dectomax...as long as i dont blame him if she drops down dead he says......
That's usual practice, and is called the cascade system. Vet can prescribe non-goat-licensed medicines for use in/on goats, based on licenses for sheep and/or cattle. However the responsibility is yours as the owner. It works well, and if your vet is interested in goats keep them.
It is also always cheaper to bring your goat to them for injections, blood samples etc. No call-out fee.
Re blood samples - if you want to mate your goats this autumn make sure you have a valid CAE certificate (valid for 12 months from testing), if you got them without it it is probably just quicker to get one done.
