pink noses in cur dogs

On the subject of genetics, I have a natural bob tailed Brittany. Just barely a stump. I was told to never breed 2 natural bobs together. I researched it and its called the death gene. If you breed 2 natural bobs, the pups will have intestines missing, spine can stop short, just all sorts of bad crap happens. But as long as you breed a long tail and a bob tail, its all good to a point. Bonnie has trouble with loose stools and I found out even bred like she is, the stomach/intestines can be just a little off.

Her first lit8er of pups had tails that ranged from full length to half to 1/4 to a tiny bump. Genetics can be interesting and weird at the same time.
