How big do Staffordshire bull terriers' necks grow?

This really depends on the weight and height of the individual Dog. Some bloodlines are leaner than others and so will have thinner necks, whilst some bloodlines are broad and stocky. Most Staffords will have a neck in the region of 18 and 22 inches wide.

My 3 year old female Stafford has a 20 inch neck, but every Dog is different.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
