A Goldendoodle is a cross between a Golden Retriever and a Poodle. It is one of the most popular dog breeds in the world.
Goldendoodle's coats refer to their coloring. When they are young, they have yellow fur with a brown nose and a chest. When they are adults, their fur will be more golden and their coats will be stiffer and denser.
So, the answer is yes. Goldendoodles tend to lose their coat once they become adults. It usually happens between the age of four to eight months.
