Please can we stop with the Kimbo bullshit?!
There is ZERO evidence that any of Kimbos genetics are actually here in the UK.
There is ZERO evidence that dogs related to Kimbo have killed anyone if they exist.
Twatty ego-boosting breeders claimed Kimbo lines to big up their crossbred mutts on pedigrees that are typically invented by the breeder and verified by absolutely no DNA proof at all.
One massively anti-dog outfit decided to jump on the Kimbo story and they refused to back it up with actual evidence (ie dna linking dogs to Kimbo).
XL Bullies in the UK are crossbreeds - mixtures of staffie, pitbull types, american bulldogs, olde tyme bulldogges, cane corsos and much much more.
Some of them will have been selectively bred for their willingness to lunge and yell and bark and grab stuff. Many of them won't and have simply been bred for their appearance with no thought whatsoever to their parents or grandparents.
In every case to date, I can find housing, husbandry, training and health reasons for an increased potential for dangerously aggressive behaviour (vs defensively aggressive ie a dog warning folk to back off and trying to get away).
In many cases, the reason was a total lack of appropriate training and a highly aroused dog 'playing' the way they had been taught to play - grabbing at limbs and not letting go (just visit tiktok to see people teaching other people how to teach their dogs to do this!).
The common denominator in dog attacks is people - failing to meet the needs of the dogs they choose to keep, choosing highly unsuitable dogs for their circumstances, using aversive training methods, training for 'protection work' (ie, to grab people by the arm or leg).
