my dogs sure don't waddle...that walk with head held high and a very confident attitude with fluid grace.....never heard anyone use the term waddle when it comes to how their APBT moves..... IMO......Purebred Pedigreed dog and Purebred and Registered as APBTand in some cases Not registered but has a provable written pedigree history as an APBT All other choices are based on pure speculation and there is not proof...
