1. The breed is the AMERICAN pit bull terrier and so the USA should be the default place of birth ...
2. We actually used to have the default as "Unknown" ... but quickly saw that 99.99% of the people were too lazy to change it ... which is why there are so many earlier dogs with Unknown as the place of birth, etc. ... even dogs like Carver's XX (which any fool should know was a USA dog) were left as "unknown" just because the lazy person never changed it to USA where it belonged.
3. Thus, by leaving the default as USA ... again for the American pit bull terrier ... it will be correct 99% of the time for any dog entered by default, even when the person doesn't bother with it.
Assuming 99% of the users are from the USA, you are correct
In the meanwhile we have dogs with more then 10 generations of European dogs only from many different small countries. Can be hard to find out where each one of them came from.
Am i thinking to high of your brother to create a check box "set/use USA by default" ?
Its not that im to lazy, but im sure if the amount of European users on this database will increase, u will get plenty dogs with the false land of standing, rather then unknown. For the same reason people from USA are not changing unknown to USA.
Anyway, just ideas.
