Labradoodles are advertised to be hypoallergenic dogs, but because they are a hybrid breed, the actual composition of their coats may vary. There is no guarantee that an adult labradoodle will be hypoallergenic.
A labradoodle is a dog that is a cross-breed between a Labrador and a Poodle. Some labradoodles have a coat similar to a Labrador, meaning that it sheds continuously, while others have coats like poodles with minimal shedding. The minimal shedding is a friendlier option for those who are allergic to dog fur. Allergies may be triggered by other things besides the coat, including the dog's dander, saliva and urine.
