1. Ehrlichiosis: This disease is caused by a tick-borne bacteria called Ehrlichia canis. It can lead to a decrease in platelet production and destruction of existing platelets.
2. Anaplasmosis: Another tick-borne infection caused by the bacteria Anaplasma platys affects platelets and can result in thrombocytopenia.
3. Babesiosis: This infection is transmitted through the bite of infected ticks and is caused by Babesia protozoa. It can cause destruction of red blood cells and platelets.
4. Leptospirosis: This bacterial infection is spread through contact with contaminated water or soil. It can affect multiple organs, including the bone marrow, leading to a decrease in platelet production.
5. Canine Distemper: This viral infection can affect various body systems, including the bone marrow. It can result in a reduction in platelet production and lead to thrombocytopenia.
6. Viral Infections: Some viral infections, such as Parvovirus and Canine Herpesvirus, can also cause bone marrow suppression and lead to low platelet counts.
7. Fungal Infections: Certain fungal infections, like Blastomycosis and Histoplasmosis, can affect the bone marrow and result in thrombocytopenia.
8. Bacterial Infections: Severe bacterial infections, such as Sepsis or Endocarditis, can cause disseminated intravascular coagulation (DIC), which leads to widespread activation of the clotting system, including platelets, resulting in their consumption and low platelet counts.
9. Parasitic Infections: Some parasites, such as Hookworms or Leishmania, can affect the bone marrow and lead to a reduction in platelet production.
10. Protozoal Infections: Protozoal infections, like Trypanosoma cruzi (causing Chagas disease) and Haemobartonella felis (causing feline infectious anemia), can also cause thrombocytopenia in dogs.
It's important to note that thrombocytopenia can also occur due to other causes, such as immune-mediated disorders, cancer, certain medications, or toxins. If your dog has low platelets, it is essential to consult a veterinarian for proper diagnosis and treatment based on the underlying cause.
