Some Labradoodles do have a smell to them that is not very pleasant especially when the Labradoodles fur coat gets wet or damp.
However the smell is not all that bad.
As long as you groom the Labradoodles fur and bathe the Labradoodle often enough then you should not notice much if any smell from the Labradoodle.
One type or breed of Labradoodle such as the Australian Labradoodle does not have the bad smell to it like other Labradoodles do or other dogs do.
The Australian Labradoodle has a non shedding coat that has no bad smell to it.
So if you want a non smelling Labradoodle then you should try to get an Australian Labradoodle dog.
