Inherited clotting deficiency, or canine hemophilia, is a genetic issue. It stops a dog’s blood from clotting well. Dogs may show signs like unusual bruising, too much bleeding, or bleeding for too long after being hurt or having surgery. To figure out if a dog has this disorder, vets use tests. They check the number of platelets, screen coagulation, and assess clotting factors. Treatment options include giving blood and plasma, adding vitamin K to their diet, and keeping a close eye on the dog’s health.
Key Takeaways:
- Hemophilia A is the top severe inherited clotting issue in dogs and people1.
- It happens because of a lack of Factor VIII, a crucial clotting factor1.
- The Factor VIII gene is on the X chromosome. This causes X-linked recessive inheritance1.
- Male dogs with one bad Factor VIII gene get hemophilia and pass it to their daughters only1.
- Female carriers don’t show symptoms but have a 50% chance of passing the gene to their kids1.
- Hemophilia can cause deadly bleeding inside the body of dogs1.
- APTT tests are key in diagnosing hemophilia in dogs1.
- Lab tests for hemophilia in dogs are very accurate1.
- Checking a dog’s family tree is vital to see if females carry the gene1.
- Looking at pedigrees confirms the diagnosis and helps track the risk in relatives1.
- Cornell University provides tests to identify hemophilia A in dogs and find carriers1.
Causes of Clotting Deficiency in Dogs
Clotting issues in dogs stem from different reasons. One key reason is not having enough vitamin K, which helps blood clot. This vitamin is crucial because the liver needs it to make enzymes for clotting2. If the liver doesn’t get enough, it won’t work right. Another common cause is genetics. Dogs can inherit hemophilia, a condition that results from having too little of a specific clotting protein. This is more serious in male dogs and carrier females because of how the genes pass down21.
Things in the environment can also mess up a dog’s clotting ability. For example, eating rat poison or getting bitten by a snake can bring dangerous toxins into the body2. Also, long-term use of certain drugs like antibiotics or Heparin can harm clotting2.
Finding and dealing with these issues is key to helping dogs with clotting problems. Vets need to understand what’s causing the issue to diagnose and plan treatment correctly. By eliminating outside factors and testing blood clotting, they can find the exact problem2.
To treat clotting issues, dogs might need hospital care, including blood and plasma transfusions, and vitamin K supplements. Vets will also watch how the treatment goes and check for any bad reactions to transfusions2. It’s very important to understand why clotting problems happen. This knowledge helps prevent them and keeps dogs healthy. Though any dog can face these issues, knowing their family history helps breeders make smart choices2.
Summary:
Various factors can cause clotting problems in dogs, like not enough vitamin K, genetics, and environmental dangers. Finding and treating these can help manage the problem, ensuring dogs stay healthy.
Symptoms of Clotting Deficiency in Dogs
Dogs with clotting deficiency may show a variety of signs pointing to blood clotting problems. These symptoms include:
- Prolonged bleeding after an injury or surgery2.
- Weakness and tiredness, stemming from blood loss and anemia2.
- Difficulty breathing and heartbeat irregularities due to less oxygen in the blood2.
- Confusion and odd behavior, caused by low oxygen to the brain from internal bleeding2.
- Pica, where dogs eat non-food items to make up for lost minerals from bleeding2.
- Seeing blood in vomit or stools, showing gastrointestinal bleeding2.
- Bleeding from behind or during peeing, suggesting internal bleeding2.
- Trouble breathing, from bleeding into the lung area2.
- A bloated or firm belly, indicating internal bleeding2.
- Drinking more water than usual, due to dehydration from losing blood2.
If your dog shows any of these signs, getting help from a vet right away is key for a right diagnosis and to start treatment2.
Quote:
“It’s vital to catch clotting deficiency signs in dogs early. Never ignore prolonged bleeding, weakness, breathing issues, or other symptoms as they could signal serious clotting problems.”
The symptoms listed can link to different clotting deficiencies, from genetic conditions like hemophilia to acquired ones due to other causes or medicine use13. Remember, the seriousness of symptoms can change based on the specific condition and the dog itself.
Diagnosis of Clotting Deficiency in Dogs
If your dog might have a clotting deficiency, a vet will first check if something like rat poison or a snake bite could be the cause. They’ll do a full blood test to see how well the blood can clot. They might also test for specific clotting factors.
If there’s a high number of red blood cells, it could mean the dog is losing blood internally. But remember, the tests aren’t perfect. Sometimes, the problem must be really bad to be detected2.
Treatment for Clotting Deficiency in Dogs
If your dog has a clotting deficiency, quick action is vital. It helps prevent more health issues and keeps your pet safe. The treatment type depends on the clotting disorder and what causes it.
Dogs with genetic clotting issues need special care. For example, Doberman Pinschers with Von Willebrand disease, German Shepherds with Canine Scott syndrome, and Great Pyrenees with Glanzmann’s thrombasthenia should avoid surgery. This lowers the risk of bleeding problems. They might need cryoprecipitate transfusions for short-term bleeding control and desmopressin injections. These injections help release a necessary clotting factor4.
For clotting issues caused by toxins or infections, the main focus is on the root cause. This can include removing toxins from the body, giving antibiotics or antivirals, and supportive care. All these help the dog heal better4.
When rodent poison or other factors cause a vitamin K deficiency, vets often suggest vitamin K supplements. Vitamin K is essential for making clotting factors in the liver. By increasing its levels, a dog’s blood can clot properly again4.
Managing a dog’s clotting deficiency involves regular check-ups and blood tests. These help check if the treatment works and if any changes are needed. Vets keep a close eye on how the dog reacts to the treatment. They aim to make sure your pet stays healthy and happy4.
Treatments for Clotting Deficiency:
| Treatment | Explanation |
|---|---|
| Blood and plasma transfusions | These may require a stay at the hospital to control or stop more bleeding4. |
| Vitamin K supplementation | This is given to boost low vitamin K levels and help the blood clot again4. |
| Cryoprecipitate transfusions | These transfusions give clotting factors to dogs with genetic clotting issues for quick bleeding control4. |
| Desmopressin injections | These shots help release von Willebrand factor, which is crucial for clotting in some inherited conditions4. |
By working closely with a vet, owners can make sure their dogs get the right care for clotting issues. This helps prevent too much bleeding and improves their pups’ life quality.
Prevention of Clotting Deficiency in Dogs
Preventing clotting issues in dogs is key to their health. There’s no sure way to stop this condition, but knowing about genetics helps a lot2. When dogs inherit clotting problems, they shouldn’t be bred. This stops the problem from being passed to puppies. Choosing dogs without these issues for breeding helps lower the risk in some breeds.
It’s also important to notice and deal with outside dangers to a dog’s clotting function2. These dangers include rat poison, snake bites, or some medicines. Keep your dogs safe from these risks to cut down their chance of getting clotting problems.
Vets are crucial in this prevention work. Regular visits and complete health checks can spot risks early. When needed, vets might suggest vitamin K. This vitamin is crucial for blood to clot properly2.
Breeding and Preventing Hereditary Clotting Deficiency
Hemophilia is a bleeding disorder that dogs can inherit. So, it’s important to choose dogs for breeding carefully. This condition is linked to genes, especially on the X chromosome.
A male dog with the wrong gene on its X chromosome will get hemophilia A. He can give this gene to all his daughters but not his sons1. If a female has one wrong gene, she won’t show signs but can give the gene to half of her puppies3. That’s why it’s important to think hard before breeding dogs that might carry the wrong gene.
Testing for carriers and looking at family history helps make smart breeding choices. Working with vets and gene experts can set up breeding plans. These plans aim to stop inherited clotting issues in dogs.
The Role of Genetic Screening
Genetic testing is crucial to fight inherited clotting issues in dogs. New tests can find gene mutations that cause these disorders3. Early detection from these tests can lead to prevention.
Through genetic tests, breeders can pick the right dogs to breed. This ensures dogs with these genetic issues do not breed. This smart approach stops the issue from spreading. It also keeps future dog generations healthy.
| Disease | Inheritance Pattern | Prevalence |
|---|---|---|
| Hemophilia A | X-linked recessive | Most common severe inherited coagulation disorder in dogs and humans |
| Hemophilia B | X-linked recessive | Identified in over 25 dog breeds |
Combining breeding strategies with genetic tests helps fight inherited clotting issues in dogs3. By focusing on the health of future dogs, we can prevent many of these problems.

Hemostasis and Clotting in Dogs
Hemostasis stops bleeding and helps clots form in dogs. It needs platelets, clotting proteins, and tight blood vessels.
After an injury, broken blood vessel walls make platelets come quick. These tiny cells change shape to stick to the damaged area and each other. This sticking starts the clot.
Then, in the blood, fibrin strands weave into a mesh. This mesh, with platelets and cells, seals the vessel break. It stops more bleeding and helps the wound heal.
For clotting to work right, a dog’s body keeps a balance. Blood proteins work as checks to stop too much clotting. They also break down clots when they’re not needed anymore.
Platelets, clotting factors, and fibrin work together in dogs. This lets blood clot well, controls bleeding, and helps with healing after an injury.

Congenital and Acquired Bleeding Disorders in Dogs
Bleeding disorders in dogs can start from birth or develop later. Congenital disorders are often due to clotting protein issues. Acquired ones might come from medicines, the environment, or infections. Each disorder has its own signs based on the defect.
Congenital Bleeding Disorders
Congenital disorders cause delayed bleeding and deep tissue bruising. For instance, Saint Bernards and Vizslas often have hypofibrinogenemia6. Beagles and other breeds might lack Factor VII6. Hemophilia A, lacking clotting factor VIII, is another common issue in dogs6.
Acquired Bleeding Disorders
Acquired disorders appear later due to factors like medication. Things like toxins or infections also play a role. Dogs might show bruises, nosebleeds, or have prolonged bleeding, pointing to platelet issues6.
| Breed | Common Bleeding Disorder |
|---|---|
| Doberman Pinscher | Von Willebrand’s Disease |
| German Shepherd | Von Willebrand’s Disease |
| Golden Retriever | Von Willebrand’s Disease |
| Miniature Schnauzer | Von Willebrand’s Disease |
| Pembroke Welsh Corgi | Von Willebrand’s Disease |
| Standard Manchester Terrier | Von Willebrand’s Disease |
| Standard Poodle | Von Willebrand’s Disease |
| Scottish Terrier | Von Willebrand’s Disease |
| Basset Hound | Von Willebrand’s Disease |
| Shetland Sheepdog | Von Willebrand’s Disease |
| Basset Hound | Canine Thrombopathia |
“Over 70% of 15,000 tested Dobermans have von Willebrand’s disease”7.
“NSAIDs, estrogens, and penicillin may up the bleeding risk in dogs with this disease”7.
Testing and Diagnosis of Bleeding Disorders in Dogs
Getting the right tests done quickly is key to understanding bleeding disorders in dogs. Blood clotting tests check how well clotting proteins work. They help spot these issues and guide treatment. But, sometimes, these tests may miss smaller problems and only catch bigger ones.1
New tests are being made to get better at finding these disorders. They look more closely at genetic issues causing the disorders. These tests are not common yet, but they’re expected to improve diagnosis a lot.3
When doctors think a dog might have a bleeding disorder, they look at everything. This means ruling out other causes and doing a full blood review. They pay special attention to clotting factors like factor VIII. Checking platelet function and other key details is also vital.1
Knowing if a dog could pass on a bleeding disorder is hard, especially in female dogs. This is when looking at the dog’s family tree and tests become important. Doing so helps make the right choices for breeding. It also reduces the chance of passing the disorder to puppies.1
Screening for Hemophilia A
Cornell University’s Diagnostic Lab offers private testing for Hemophilia A in purebred dogs. Just send in a blood sample following their guidelines. This check-up finds if a dog has Hemophilia A. It helps breeders make smart choices and lowers the disorder’s spread in breeds.1
Identifying bleeding disorders in dogs means looking closely at clotting factors, how platelets work, and the dog’s family background. With cutting-edge tests and proper screening, we can better find and manage these disorders. This leads to healthier and happier dogs.
Management and Treatment of Bleeding Disorders in Dogs
The management and treatment of bleeding disorders in dogs depend on the cause and how severe it is. If managed well, excessive bleeding in dogs can be prevented or controlled.
Blood transfusions might be needed for dogs with such disorders. These transfusions can give dogs the clotting factors and blood components they need.
Another treatment is clotting factor replacement therapy. It gives dogs the specific clotting factors they’re missing. This helps their blood clot correctly, lowering the risk of bleeding without reason.
Some dogs might also need medication to deal with certain deficiencies. For dogs with von Willebrand’s disease (vWD), desmopressin acetate (DDAVP) could be helpful. Yet, this treatment doesn’t work for every dog with vWD.
Regular vet visits are crucial for dogs with bleeding disorders. These visits let vets check if the treatment is working. They can change the plan if necessary.

| Von Willebrand’s Disease | Doberman Pinschers, Scottish Terriers, Shetland Sheepdogs | 7Highest incidence in Doberman Pinschers, significant prevalence in Scottish Terriers and Shetland Sheepdogs7 | Genetic predisposition, certain medications7 |
With the right care, dogs with bleeding disorders can still enjoy life. By being careful and checking on them often, you can keep them healthy. Quick visits to the vet when needed also play a big part in managing their condition.
Conclusion
Inherited clotting deficiency in dogs is uncommon. It leads to prolonged bleeding, anemia, and internal bleeding. About 1 in every 500,000 to 1,000,000 humans have it, showing it’s rare in people too. Veterinary experts also believe it’s rare in dogs8. Some dogs can carry the gene without showing symptoms, making it tricky to find and understand how widespread it is8.
There’s a unique case of a Chihuahua with Factor X deficiency. It’s the first time this has been seen in this breed8. The dog’s Factor X activity was very low, indicating congenital deficiency. Thankfully, treatment helped maintain its Factor X levels, showing good management of the condition8.
Factor VII deficiency is another rare bleeding disorder. It affects about 1 in 500,000 people. This issue isn’t limited to one kind of dog – it’s found in 24 different breeds and mixes9. A certain gene, the F71 variant, linked to Factor VII deficiency can be found in mixed and purebred dogs. It’s a very old gene, found in many breeds9.
Looking after a dog with a bleeding disorder is serious. It means regular vet visits and being careful to prevent injuries that could cause bleeding. Doctors can diagnose the disorder with blood tests and recommend treatments like blood transfusions or vitamin K. Dog owners can also limit risks by steering clear of activities that could hurt their dog8. With the right care, dogs with these conditions can live happy, safe lives.
