An English "Block Head" TeddyBear Labradoodle is a hybrid created 

from the breeding of an English Block Head Labrador Retriever and a Poodle. 

The English Block Head Teddy Bear Labradoodle ranges in size from

Small ~(20-35 pounds as adults)

Medium~(30-45 Pounds as adults) 

Large~(50+ lbs at maturity)

The size depends on the size of the Poodle that 

the English Labrador Retriever is crossed with. Labradoodles can also be

bred back to a poodle to create a more allergy friendly dog that is even

 less likely to shed and be more hypoallergenic.
