A Goldendoodle is a Golden Retriever and Poodle cross rather than a standardized breed, which is why one dog can weigh 20 pounds and another 80. Coats range from straight to loose waves to tight curls, and shedding varies. No Goldendoodle is guaranteed to be hypoallergenic, and adult dogs are the easiest to judge, since their size, coat and behavior are already clear.
Many inherit the Golden's friendliness and the Poodle's quick mind, so they like training, people and play. They also need daily exercise, company, and regular brushing and clipping, since wavy and curly coats mat easily. In Fort Collins, that means trail time, a coat that copes with snow and burrs, and a household where someone is home fairly often.
