What range of CI was found in the UK study?
The average breed CI in this study ranged from 2.4% in Labrador Retriever to 7.3% in Rough Collie. For individual dogs, the maximum CI ranged from 32% in Akita Inu to 50% in four Boxers. This indicates that the most inbred of all the 2.1 million dogs in this study are half-way towards becoming an inbred animal, i.e. they are still a long way from being true-breeding. At the other extreme, the UK study showed that more than 90% of dogs in the nine breeds were the result of matings less close than second-degree relatives.
