Agree with everything everyone else has said.
As someone who has worked with Stafford rescue both in the UK and overseas, I can only reiterate that there are far too many Staffords being bred willy nilly!
And you may or may not be aware that this is particularly the case with the blue Stafford.
Sadly people just trying to make a quick buck.
I'd very much recommend NOT to breed from your Stafford. Bear in mind that the blue colour in a Stafford is actually a dilution of the black coat, which CAN in SOME cases cause skin problems.
edit: he IS only very young still, and bearing in mind that some Staffords take a good couple of years to mature both physically and mentally, 11 months of age to most would be too young.
Please just enjoy him for what he is.
