My dog has severe seasonal allergies. Could this cause low platelets?

The main two things i would suspect is Tick fever caused by a bacterial called Erlichia (it is treated with an antibiotic called doxycycline). it could also be an autoimmune hemolytic crisis, this will need to be treated with steroids.

Hello. Platelets are needed for blood to clot, so if platelets are low you will see actual bruising ( black & blue spots ) or discrete blood spots in the skin or on the mucous membranes. A simple CBC ( complete blood count ) will report the number of platelets *& tell you if there is a problem or not. What you are describing with the redness & inflammation sounds more like an allergic reaction, something that can affect the skin in this area very commonly. If you are worried about platelets, consider having the blood work done. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hello, I am sorry to hear about Daisy. Based on the blood work abnormalities it is possible that Daisy has an infection secondary to tick borne disease or another organism. Many of these diseases cause destruction of the platelets. The white blood cells are part of the immune system and fight infection. It is possible that this value went up despite being on treatment secondary to fighting a severe infection. However, if Daisy is still not feeling well or these counts don’t improve it may be possible that Daisy’s platelets are low due to a different cause such as immune mediated disease. Your veterinarian can help assess for this kind of disease and determine if treatment is needed if Daisy’s blood counts do not improve or she is clinically ill. Hope this helps, good luck!

The problem here is to establish the underlying cause of thrombocytopenia (low platelets). Immune-mediated thrombocytopenia is one of the most common causes. This process usually occurs in the spleen although the liver also plays a role. Thrombocytopenia develops as platelet destruction exceeds compensatory production by the bone marrow. Immune-mediated thrombocytopenia can be classified as primary or secondary. Secondary processes can be caused by infective diseases or tumors very commonly. Usually to determine a diagnosis more tests needs to be performed like abdominal ultrasound and chest x rays. Infective diseases like Ehrlichia, Anaplasma spp for example should be ideally evaluated as well. Hope this answer was helpful, but please do not hesitate to contact us again on the forum (where you can post pics of the blood tests) or by requesting a consultation if you have any more questions or to discuss it any further.

Immune mediated disease or rat poison is a possibility since tick disease have been ruled out. Prednisone or prednisolone is typically recommended to start as a steroid. Dexamethasone is an option also, it is a lot stronger than prednisone so the GI side effects can be worse, but not a wrong option.

This looks more like a skin condition rather than a low platelets problem, it could be an allergy or a skin infection, if it doesn't resolve within 72 hours i would recommend taking him to the vet in order to get it checked and treated.

I wouldn't say limping is the cause of low platelets. Sometimes platelets clump together and the machine cannot appropriately read it. I recommend having your veterinarian evaluate a blood smear to make sure they are low. Thank you for using Petco Pet Education Center, formerly Petcoach.
