Welcome mate,on the subject of irish staffs i used to breed them only lost my last one 2 months ago at 14 and he was a great dog and very slow to anger infact in all his years he never started a fight,loved my kids to bits,my mother used to say he was anyones for a big apple .
I am great beliver in it's how you bring the dog up not the breed,only a bad dog will so aggression to humans,kids especially and not worth shit only a bullet!.
still have friends that breed quallity dogs if interested.
