Factor 7 is a potential delay in blood coagulation, during times of trauma. 

So, it isn’t the same as hemophilia where the dog bleeds out as they don’t coagulate at all.  It wouldn’t impact them in a time of non-trauma like running around the yard and hurting themselves on a stick.  

The potential would come into play with times of trauma – being hit by a car, or something else traumatic – there is a higher likelihood of blood taking longer to coagulate – but not guaranteed that this would even happen.

Ruth Stewart, AKC judge and long time breeder has written up an excellent article with examples of “affected dogs” that have not been impacted by their F7 – http://www.aladarbeagles.com/factor7.html  It is definitely worth a read. 

What would it mean for you if your dog was “affected”? 

What I recommend to my dogs who are “affected” is to give them vitamin K in the days leading up to a spay/neuter, and to inform the vet so they can have plasma on board “just in case”.
