Hi Nutkin, interesting to know - I always have sterzac on hand in case of problems. We used to subscribe to the theory that hernias could be caused by too much roungh handling by Mum, this line of thought was rubbished by our vets. We have done a small study of the problem (only with our own dogs) and it seems pretty clear (at least in my breed) that they are inherited. Whilst 1 line always throws at least 50% with hernias, 2 other lines throw none at all, through 3 generations. When we have crossed the "always" with the "never" lines, 2 generation down the line, we get about 1 pup per litter with a hernia. (very rough figures) This tends us to thinking that it is a recessive, simple mode of inheritance. Would be keen to know what other people have found.
