The incidence of pancreatic degenerative atrophy (PDA) was investigated in 59 German shepherd dogs from two kkindred. The male progenitors were the same in both indred. In the four litters of the first kindred the incidence of PDA was 24 per cent (10 dogs out of 41), and there was at least one affected dog in each litter. When one of the litter bitches, later affected with PDA, was mated with one of the obligate carriers of PDA, one of the resultant seven offspring has so far been found to suffer from PDA. In the second kindred when a PDA-affected bitch and a clinically healthy male (heteroxygote) were mated, two of the resultant six offspring were found to suffer from PDA. These results indicate that PDA is a disease inherited as an autosomal recessive trait, although the possibility of dominant inheritance with incomplete penetrance cannot be excluded
