This means that your Goldendoodle likely has straight or flat hair throughout their body and they look like a Golden Retriever.
There are slightly more variations to improper coats and furnishings, such as a weak furnishing gene.
The easiest way to prevent an improper coat and allow for furnishings is to breed with a Poodle that is fully furnished with (FF) genes.
If you want your Goldendoodle to be curly and wavy without any shedding then you will need to opt for FF genes. If you see Fw genes with IC genes, then there is still a chance that your Goldendoodle will shed.
A Goldendoodle with a flat or straight coat is the easiest way to identify an improper coat without genetic testing.
