Trouble is, an outright ban would bring about even more underground/unlicensed breeding (litter round my way over summer), it’s all about the money.
Statistically, the numbers show that labradors are more likely to bite (not kill!) purely because of how many are registered annually: a quick look on a popular selling site shows almost 700 litters for sale today (compared to 180 springer litters).
As already mentioned, any dog (including the much touted spaniel, I’ve had one that was an absolute horror with other dogs and would snap at people, he was attacked as a baby and totally changed 😢, had to be muzzled, of course) can be aggressive.
