F1 refers to the mix between two purebred dogs- A Bernese Mountain Dog bread with a Poodle or a Golden Retriever bread with a Poodle. This generation cross gives a 50/50 mix, genetically they will have a combination of attributes between the
two parents. Coats in F1s can vary in terms of the percentage of hair shedding. This is usually a major factor in determining which is best for you. Some F1s will be nearly completely non-shedding and others will have a percentage of hair that still sheds.
F1b’s are a Bernedoodle crossed to a Poodle- making it 75% poodle, their coats are usually fairly consistently, low to non-shedding. Typically half of the litter will have a curly coat and half will have a looser wavy coat. They are recommended for a
family that may have mild allergies or that feels strongly about shedding in their dog.
