If a Maltipom is bred back to a Maltese parent, what is the likely resulting effect on the puppies' average weight compared to an F1 cross?

Answer

Result in smaller puppies overall

Breeding a first-generation cross back to one of the parent breeds can influence the outcome; breeding back to the smaller Maltese generally results in smaller puppies.
