COI AND AS
COI - COEFFICIENT OF INBREEDING.
In view of possible health problems relating to inbreeding within dog breeds and also from a moral point of view it is now seen as wrong to put mother to son, father to daughter and indeed cousins to each other when mating dogs.The percentage of COI within a mating can now be calculated using the MATE SELECT programme on the Kennel Club Website.
The average reading for a Boxer is 7.3%. However in Sweden there has not been a COI of over 6.5% for a number of years.We, at Bedtime Boxers, always check pedigrees and work out COI before every mating and our average reading is 4.5%. Giving us a low percentage of inbreeding within our puppies family tree.
AS - AORTIC STENOSIS
Aortic Stenosis is a congenital narrowing at the entrance to the aorta within the heart which supplied blood to the body. This then causes the left ventricle of the heart having to push blood through to the body with greater force. This causes what is referred to as a heart murmur which is the sound of the blood flowing through the heart.Heart murmurs are measured on a scale of 0 to 6 with 6 being quite severe.This problem has been detected in Boxers which is why they are heart scored by a cardiologist. The information is then passed from the cardiologist to the kennel club and the owners own vet.
All responsible breeders will have their Boxers heart tested.
