Plain-English summary
A group of 80 mixed breed dogs, aged 3 to 5 years, were tested for heartworm infection (Dirofilaria immitis) after showing symptoms. Out of these, 20 dogs were found to be infected, which is about 25% of the group. The infected dogs had lower levels of red blood cells and hematocrit compared to healthy dogs, while their white blood cell counts and certain other blood components were higher. This suggests that heartworm infection can significantly affect blood health in dogs. Treatment for heartworm typically involves medications to kill the worms, and early detection is crucial for a better outcome.

Abstract
This study was conducted on 80, 3-5 year old mixed breed dogs suspected of dirofilariasis in the Faculty of Veterinary Medicine, Islamic Azad University of Tabriz. The direct method and the modified knott’s method were used for diagnosis of the parasitic microfilaria. Hematologic parameters including white and red blood cell and platelet counts and the amounts of hemoglobin and hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), fibrinogen and protein were determined. This results of this study indicated that 20 of the 80 dogs examined were infected by Dirofilaria immitis microfilaria and the prevalence of dirofilariasis in this study was 25%. The mean levels of hematocrit, red blood cells and MCV in infected dogs were decreased significantly in comparison to the un-infected dogs and the mean levels of hemoglobin, MCH, MCHC and platelets did not show any significant differences. The mean levels of fibrinogen, protein, white blood cells and absolute and relative neutrophiles, eosinophiles, monocytes and basophiles were increased significantly and the mean levels of absolute and relative lymphocytes were decreased significantly in infected dogs compared to the healthy dogs.
