It pays to check out dog breed regulations where you are living as it differs from place to place.
In some areas, it is illegal to breed any Pit bull mix, while in others, mixes are fine but it’s illegal to sell any purebreds.
This is because these dogs can be aggressive if they are not socialized properly, which requires a high level of commitment from the owner. Authorities are wary that people won’t commit to this and dog bite statistics of badly socialized and poorly-bred breeds can be high.
