Your dog is not an American Bully at all. Luke (Empire Strikes Back) is far from a big dog. He stands Just shy of 19 inches and may go at his largest 60 pounds. He does have bullier features but the dogs at Blue Diamond would not fit in the AmBully show ring.
The other part of your ped goes to Gaff dogs I actually saw Smoke as a pup and compete against his brother and sister, Apollo and Timber both very far from the AmBully standard.
Blue Diamond dogs have not been mixed with anything! I will put it on whatever anybody wants. I personally know the breeder and his feelings on the AmBully. People are giving people false information, just because you see RE does not make it a AmBully. Look at BD dogs and you can see a difference nor only in style but in type, when compared to ABKC dogs.
As far as bloodlines go, Mr Baker has been breeding for over 15 years and although questioning BD as a bloodline is fine, I would say he at least kept his strain of the RE blood, geared towards UKC show dogs.
I am posting this from my phone, but I will post pics of conditioned ancestors of your dog and show you what they are.
I'm not here to call anyone out but I will definitely be speaking on this issue next Tuesday, because some of the overall generalization of all things RE, Gaff or Gotti is AmBully is pure garbage, and to spew it to newbies is not helping the situation in my opinion.
Anyone who has read any of my posts or heard my show knows that I stand by the idea of calling AmBullies, Am Bullies and ApBts Apbts!
However, I also know several breeders of the RE line who still breeds to the RE style of 10 to 15 years ago. I know they are not caught up in the AmBully craze and although their dogs carry more bone and slightly larger head I still feel they are producing balanced dogs.
So to answer the original poster YOU DO NOT HaVE an AmBully. The dogs your dogs come from are UKC show dogs for the most part. A few are larger than ideal but overall balanced, I know the faults of the line, or of dogs produced from this particular kennel.
Do your research contact the breeder and I guarantee you will find the info you are looking for.
