Details about the disease
Clinical signs
Affected dogs may have a range of effects, including bruising easily, nosebleeds, longer than usual periods of bleeding if cut, and stiffness, which may be a sign of damage to muscles or joints. In severe cases, bleeding can be life threatening, but most dogs do live a normal lifespan.

Where will your dog's results be published?
DNA test results from these laboratories are sent directly to The Kennel Club and are recorded on to the dog's record in the registration database, and are published:
- in the next available Breed Records Supplement
- on our Health Test Results Finder
How are results recorded?
Male dogs that have been tested for this condition can be described as either clear or affected.
Clear
If your dog is clear they will not have any copies of the abnormal gene associated with FVIIID and will only pass on a normal copy of the gene to any offspring.
Carrier (females only)
If the female dog is a carrier they will have one copy of the normal gene and one copy of the abnormal gene associated with haemophilia A. The dog will not be clinically affected by the disorder, but may pass one copy of the abnormal gene on to its offspring.
Affected
Male dogs will have one copy of the abnormal gene associated with haemophilia A, while the females will have two copies. The dog will be clinically affected by the disorder. If bred from, females will pass on a copy of this abnormal gene to all of their offspring and so will produce affected male puppies and carrier or affected female puppies, while males will pass the copy of the abnormal gene to their daughters/female puppies but not sons/male puppies. It is advised that you speak to your vet about the results of this test to determine how this condition may affect your dog.

Breeding advice
The decision you make when choosing which dogs to mate must be informed and carefully planned.
If the health status of both sire and dam are known, the likely health status of any puppies produced can be predicted.
Please use the following table to note the outcome of mating a male and female with a known hereditary status:
Clear male | Affected male | |
---|---|---|
Clear female | All puppies will be clear |
All male puppies will be clear All female puppies will be carriers |
Carrier female |
Risk of producing affected male puppies and risk of producing carrier female puppies |
Risk of producing affected male puppies and risk of producing carrier female puppies |
Affected female |
All male puppies will be affected and all female puppies will be carriers |
All male puppies will be affected and all female puppies will be carriers |
If your dog is clear
Mating clear females to affected males should only be carried out if it does not pose a risk to the males welfare. Any female puppies produced from this mating will be a carrier and should not be used for breeding, but may be good for a pet home, providing appropriate breeding restrictions are placed in any puppy buyer contracts.
If your dog is a carrier (females only)
If your dog is affected
Affected male dogs should only be bred to clear females and only if the mating does not pose a risk to his welfare. Any female puppies produced from this mating will be a carrier and should not be used for breeding, but may be good for a pet home, providing appropriate breeding restrictions are placed in any puppy buyer contracts.
