The Kennel Club updates data for breed average Coefficients of Inbreeding each year. We've been tracking this since it was first published in 2011. Here's the summary of results for each of our six varieties of Dachshund:
The higher the CoI, the greater the probability (and risk) that two copies of a particular gene will be inherited from a common ancestor. Wires continue to have the lowest Coefficient of Inbreeding and Longs, the highest. It is interesting to note how the COI for Mini Wires has reduced over the past 6 years.
