The Goldendoodle ranges in size from small to large, depending on the variant of Poodle that the Golden Retriever is crossed with. Originally bred as a larger alternative to the already popular designer breed known as the Cockapoo, the Goldendoodle has proven to be an excellent family dog. They're also versatile working dogs. Goldendoodles have achieved success as guide dogs, service dogs, therapy dogs, and sniffer dogs (one study tested their success at sniffing out peanuts in foods for owners with nut allergies). Goldendoodles have also done well in agility. The Goldendoodle is an affectionate and gentle dog that has gained popularity since he was first developed in 1990s. He's still a young cross compared to other designer breeds, and many of today's litters are the results of first-generation breedings between Poodles and Golden Retrievers. Goldendoodles are usually highly social and get along well with everyone. They don't do well in any type of guarding or watchdog role and should not be used in that capacity. They can thrive in both city and country settings, but they're not well suited to apartment living, since they do better with the space provided by a fenced yard. Goldendoodles should not live outside or in a kennel, however, since they thrive when they are in contact with the people they love. Goldendoodles can be very easy to train and are a good match for first-time or timid owners. They're not known to have any aggressive traits, but they do need proper socialization to avoid any shyness or fearfulness. Goldendoodles also need daily contact with their owners; they'll suffer from separation anxiety if they're left for too long. The best way to avoid any destructive behavior is to crate them and to provide toys and treats to keep them busy throughout the day. Keeping the radio on when you're out is another great way to keep them happy. Goldendoodles are considered to be non- to light shedders and may be a good match for people with allergies. They do require weekly or biweekly brushing, and many owners opt to have them clipped. Although Goldendoodles are a young designer breed, that hasn't stopped people from understanding their worth. They have become popular quickly, and their star is still rising. They make excellent family dogs and provide gentle, intelligent companionship throughout their lifetimes.
