Hello and thank you for asking your question. My name isXXXXX will try to help.
Belly button, navel, and the umbilicus are all the same things. It is where the placenta attached to the upper abdomen of the puppy. When the mom bites, or tears, the umbilical cord, a little too much force can be applied. So the musculature around the (navel) belly button tears. The tear is a gap in the abdominal muscles. The gap is called a hernia. So an umbilical hernia is a gap, in the abdominal musculature, where the belly button, or umbilicus, is located.
As long as it is smaller than the size of a dime, I would not be too worried.
The larger the hernia, the greater the chance that the intestines, or other intra-abdominal structures, can leak through the hernia and get stuck. That could cause a problem as the blood supply to the stuck structure would be compromised.
So, that rarely happens if the hernia is small.
It can happen in larger hernias though.
I would call the vets, in your area, and get a few quotes for the price of an umbilical hernia repair. Ask for the price of the repair with a neuter if you are getting a male.
Then, the breeder should take that cost off the price of the puppy.
But if you really like the puppy, and the breeder, I would not hesitate to get the puppy if it has a small umbilical hernia.
I hope this helps.
If you have additional questions, please reply.
Thank you Dr. Gabby! I do have a f/u question. A dime is roughly 1.5cm in diameter. I haven't seen the puppy yet, and won't get to see him until he is 8 weeks old on November 6th. Will this critical measurement of 1.5cm still be the same at that age....in other words, the measurement is not related to the size of the puppy, correct? So, whenever I see the puppy and the hernia is larger than 1.5cm, this would be a red flag?
Thank you and have a great day!
If it is a little larger than a dime, I would not worry too much. If it is larger than a quarter, I would probably look for another puppy. The hernia should not noticeably increase in size in two weeks.
If you get the puppy, you need to monitor the hernia for change or growth.
As I mentioned, there should not be a noticeable size increase in the hernia as your puppy grows. If you come home one day, and the hernia looks much larger, then you would need to have him checked by a vet.
