Thanks hadn't thought of this a will ask the vet and see what he thinks
it wouldn't be a common thing ..but while the blood is being tested ..it may as well have a tox screen too!
Did the vet consider anti coagulant rodenticides as a cause?
Are /were the dogs on any treatment , eg : vit K to stop the bleeding ?
Obviously being of the same breeding , a genetic problem is entirely possible ..however, lots of other things need investigating as well . Don't just let the vet say "they had/have a clotting problem" and leave it at that !! As said previously , you NEED TO KNOW .
is it lifelong , do you need to beware of injuries ? is it getting better since that episode ? LOTS of questions for the vet ! My link have a read here, too :)
Yes anti coagulants have been considered and ruled out. They are on vit k
