Hi Nutkin,
I use Sterzac powder routinely on pups cords. Pretty sure from this end that the biggest cause of hernias (especially larger ones ) is hereditary. In our parti colour lines I cannot remember one puppy in the last 9 years with a hernia - and I am sure that this is not just because the Parti bitches are more careful! With the solids, we had 2 distinct lines, one line produces very few hernias - perhaps 1 in every 3 or 4 litters. The other solid line descends from 1 bitch, and produces almost 50% of pups with hernias. Most are small, and dont need any attention, but 1 or 2 have needed surgery. The hernia inheritance appears to be dominant, because when we have crossed these 2 lines the 50% still holds. And this is with sterzac applied.
This "foundation" bitch had a 4 year gap between first and second litter, so we didnt give much though to it till after the 2nd litter - just put the first bunch down to rough handling! When we discovered that a bunch of the 2nd litter had hernias we started a little research, and discovered that her litter sister (in the USA) had had 4 litters, and every pup in every litter had a hernia!
We now have grand-children, great-grandchildren and great-great-granchildren, and the incidence is lessening. Someone told me the other day the Shih-Tzus have a very high incidence of Hernias - any Shih Tzu people on the board?
