My dog died from tick disease. What else causes fever, nosebleeds, enlarged spleen?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 2 years and 9 months old

My dog died yesterday the vet here said it was tick disease. She had fever and nosebleeds, she passed away a week after the symptoms started. The day before she passed the vet also confirmed she had an enlarged spleen and she was very skinny but was still eating. Could it have been something else?

Hello. I am so sorry to hear about Isis. An enlarged spleen along with nose-bleeds could be due to many different disorders including tick-borne diseases that attack the red cells. Other causes could be rat bait, an auto-immune disease called "Immune mediated thrombocytopenia" or "Immune mediated hemolytic anemia" which is when the immune system attacks the platelets or the red cells. These can also occur together which can cause bleeding. Also, any severe infection can result in "DIC" or "Disseminated intravascular coagulation" which can result in bleeding. Other causes could be a congenital clotting disorder. With the fever a tick-bourne disease or an auto-immune disease are most likely. Without doing other blood tests it would be impossible to know for sure. I am so sorry about Isis. All of these diseases are unfortunately very serious and hard to treat.
