Was she given papers?
Unless your pup has papers coming from a reputable breeder and from UKC ADBA or if an AmStaff AKC then I honestly won't even bother doing any further research and would just get her spayed and love her for the great pet she is...
The dogs you listed with the Booker in front of their name, are they from her actual pedigree on the dam's side or just random dogs you found with Booker attached to the names?
For example the first dog just quickly looking at the top of the pedigree goes back to Beth Jones Blue Moon Kennel and a lot of Ruffian Bloodline
The only place where there is Booker is on that dog's name thus not Booker Bloodline IMO
A person's name at the front of a dog does not mean they are that person's bloodline. It either is the breeders name , kennel name or even just a name the owner liked. So unless you know for sure none of those may even be related. I noticed also quite a variety of Bloodlines.
To my understanding if your dogs are apbt they would not be able to register with the AKC as the AKC does not recognize the apbt . Your dog would have to be registered as staffordshire terrior with the AKC. Anyone please feel free to correct me if I am wrong. But last time I checked that was the case.
AKC = Amstaff or American Staffordshire Terrier
However UKC/AKC dual registered dogs are also considered and reg as APBTs with both UKC and ADBA as well.
So the litter is considered pit bulls.
Now iff both parents are dual registered than they are Amstaffs with one org and APBTs with the other. I know that can be confusing.
