The "breed" of an XLB is what was described in the official Breed Standard posted earlier. That is what a 100% breed-typical XLB should be like. That's what 'breed' means... and pretty much every modern breed was 'artificially created'.
Arguably the XLB breed may well have originally been bred "to develop a dog that was calmer and more adaptable than the American Staffordshire Terrier" with "the intention of creating a companionable and friendlier variant of a guard dog" and those of the founding bloodlines may well be "highly regarded as a companion and family dog, known for its sensitive and highly adaptable nature... exhibiting friendliness towards its loved ones, children, and even strangers".....
You gonna read that and still try telling me my assertion of breed not defining behaviour is false?
LOL you're actually running with the dog of peace/ackchually it's a nanny dog meme now? Seriously?
Not mutually exclusive, but they are almost entirely independent of each other.
Completely false as shown already by the study you're supposedly not denying but then repeatedly do.
So only about 13 years of breeding to get the resulting XLB and get it recognised. Probably less than 10, in reality.
And 30 years before it became a problem... it existed in the US, then later started being imported and recently has become an issue. This notion of every few years is unfounded, it was 1991 when pit bulls were banned now it's 2023 and hopefully these will be too.
