should we breed from a blue eyed bulldog or not?

No - there's a high risk of deafness being passed on, even if yours has been BAER tested (she has, hasn't she?) and has bilateral hearing.

is this the 12 week old pup you have?

The Kennel Club breed standard for the bulldog can be found here: http://www.thekennelclub.org.uk/item/155

Eyes
....... in colour very dark - almost black - showing no white when looking directly forward. Free from obvious eye problems.

So the answer is defiantely no.

no, its the sister of mine and i just wanted to ask on their behalf.

You can tell them that it would be highly irresponsible of them to do so, and just to love her as the no doubt gorgeous pet she is.

thanks - i will let them know.

I take it "we" was used in the general sense.

As the others have said it is a no no.   I would imagine she was bought as a family pet.
