Compared to a purebred Pug (14-18 lbs), what is the primary issue when predicting the adult weight of a Pugador?

The large size variance between the parent breeds.

Because the Lab parent can weigh 55 to 80 pounds and the Pug weighs 14 to 18 pounds, the resulting mix can fall anywhere in the spectrum between these weights, making prediction speculative.
