Hmmm, then the paperwork and pedigree for my pup is all bs then :/ Cuz it says she's purebred. Ahh.
Most BYB's have no clue what they are breeding and if they sold that dog as a APBT then they had no clue what type of dog they have. Bullies came from APBT's but to gain size and certian extreme looks they added in other breeds and did what is called paper hanging. For example they bred a mastiff with a APBT to gain size but registered them as APBT's and lied about breeding to that mastiff. Thus breeding what we know today as American Bullies. There is more to that story and as you do research you will learn how the bully came about.
Lets use your Avant part of your bloodline as an example
Here is a dog from Avant himself that he calls a pit bull
Notice the wide chest, short legs, huge head with huge lips? None of those are in the breed standard for American Pit Bull Terriers but they are standard in the ABKC or the Bully breed club.
Here is an American Pit Bull Terrier
This is one of my dogs who is not gamebred but a fine example of an APBT. Now compare the two dogs and do you see the difference, can you tell they are not the same breed?
Here is one of my gamebred dogs
a little different from the one above but you can tell they are the same breed and they both still fit the standard for an APBT.
Here is another one of my dogs just as another example of different bloodline but still an APBT that fits the standard.
Here is the ADBA Standard, it is not the full standard but you get the point.
Overall Appearance 20 points
A. Conforming to breed type
1. Should look like an American Pit Bull Terrier from across the ring
2. Sturdy, three dimensional. Giving the impression of strength, not slight or frail.
3. Appears square, with heavy boned, solid front end with a light and springy back end.
4. Should look athletic, not bulky. Musculature should be smooth but defined.
5. Presentation of an adult dog should be of a lean, exercised animal showing a hint of rib and backbone (without hipbones
showing) with muscles firm and defined. Clean, glossy coat with short trimmed nails. Presentation of dogs in the puppy
classes should be of a well nourished puppy, showing no ribs, backbone or hips. Coat should be glossy with short, trimmed
nails.
B. Balance
1. Equal angulation of front and rear assembly - judged best at the trot.
2. Height to weight ratio - the tallest dog at a given weight
3. Head size in proportion to the body, with a neck long enough to have the head appear above the top of the back when head
is in a normal upright position.
Here is the ABKC (American Bully Kennel Club) standard, again part of it.
General Impression
The American Bully should give the impression of great strength for its size. Compact to medium/large size dog with a muscular body and blocky head. Powerful in it's movement and should display effortless movement at the same time. Keenly alive and alert to its surroundings. The American Bully should have the appearance of heavy bone structure with a Bully build and look.
They are two different breeds even though the ADBA and UKC still register them as APBT's for now. The reputable breeders are now using the proper registry the ABKC.
