Lethality in Mexican hairless breed of dogs

Hairless condition in Mexican hairless breed of dogs is heterozygous [Hh] against the normal homozygous recessive [hh]. Puppies homozygous for H allele are born dead due to abnormalities in mouth and absence of external ears. If the average litter size at weaning is 6 in matings between hairless dogs, what is the expected number of hairless and normal offsprings at weaning from matings between normal and hairless dogs?
