The puppy I had gotten almost 4 weeks ago has a inguinal and umbilical hernia and he is doing just great!!.It hasnt slowed him down one bit.

His inguinal hernia is quite big, the bigger the hernia is the less prone it is to get stranguled. Tuckers pops in and out all day long and most of the time I leave it alone. If he is playing hard or stresses out it gets huge but we slowly massage it back in. As long as it stays soft and doesnt cause any pain when you touch it, its fine. He will have his operated on in a few weeks when we have him fixed.
His umblicial one is very small and is healing on its own.

I have done a ton of research about this and was also told by my vet that ingunial hernias are genetic. Umbilical ones are usually the result of the mom pulling on the cord to hard, happens more with first time moms, which was the case with my puppy.
If you continue to breed those parents then you may end up with a pup with a ingunial hernia in every litter.
I also wanted to ask, why wont you sell that pup? I still choose to get my pup even though I knew he had issues, the breeder offered to cover the cost of the surgery to have his hernia's repaired. You could do the same thing or you could sell the pup after its fixed.
Good luck, Im sure she is a beauty!!
