thinking of getting a new breed but not sure which is best wondered if any breeders of following breeds could give me best and worst points of each breed, from a breeders point of view :

weimeraner/vizla/rhodesian ridgeback/american bulldog/dobermann.

these are the breeds weve been looking at.

interested to know what sort of health problems they can be prone to/what size litters they have/which are best lines to choose and how much we would have to pay?

thanks alot for all your help and replies!
