Definitely can be hereditary. My CH Mattie was delivered c-section (so no, her momma didn't cause her umbilical hernia by tugging, getting too close etc). Mattie had a litter of 11, delivered naturally, right into my hands (and I do the cords) and we had a few. CH Fannie had one and produced them. Halley had one, again, I deliver the babies, and her daughter Marci also has one. Every puppy in the litter doesn't have them, who knows the transmission? None of them ever had to be surgically corrected, but yes, in those cases, hereditary.

Now, the ones in the groin area, he does feel are inherited, but not the belly button ones. He said he sees many bitches with hernias and doesn't see it in the babies. He knows on the internet there are sites that claim it is inherited. To give him credit, we do in Lancaster county, Pa. home of the puppy mills so I'm sure he does see puppies from moms with problems. What do you all think? Have you ever bred a bitch with a umbilical hernia and did she have pups with them? thanks, Sue T. ============================================================================ POST is Copyrighted 2011.
