There are 3 sizes of the Australian Labradoodle:

All Australian Labradoodles, no matter the size are indoor dogs.  If you are interested in doing some serious physical activities with your dog such as running, agility, flyball or the like, stick with either a medium or a standard size.  On the other hand, if you’re interested in the perfect small dog, the miniature Labradoodle is a great lap dog size.
