Dogs are most likely the oldest domesticated animal and have, for many millennia, been human companions (Otranto et al 2009). Jos, the capital of the plateau state, has a large population of dogs as its meat is culturally accepted as a delicacy. There is a good weather condition for exotic breeds, persistent security challenges, and dog breeding activities which are very lucrative (Momoh et al 2015). Dogs are infected with various haemoprotozoan parasites, including Trypanosoma spp., Babesia spp., Hepatozoon spp., Anaplasma spp., Mycoplasma spp. (Haemobartonella canis), Dirofilaria spp., Leishmania spp., and some of these parasites could have zoonotic importance, e.g., Babesia canis, Trypanosoma cruzi, and Ehrlichia canis and are referred to as canine vector-borne disease (CVBD) in the tropical countries (Ezema et al 2021). Companion animals such as dogs and cats are infected with haemoprotozoan parasites. This poses a severe health challenge due to their adverse effect on blood parameters and the rate of spread from one animal to another, with a significant economic impact on owners (Ezema et al 2021). Haemoprotozoan parasites in dogs have been reported throughout Africa, Asia, Europe, the Middle East, North America, and America (Nwoha et al 2013). Haemoprotozoan infections, which occur worldwide and are transmitted by arthropod vectors, pose a major health challenge in animal species because they inhabit the bloodstream and affect the cardiovascular system of the living host (Stuen 2020). While some haemoprotozoan parasitic infections result in obvious clinical signs like anaemia due to the possibility of a blood-borne infection as an underlying course, others could be subclinical (Hii et al 2012;. The common blood-borne pathogens of dogs in Nigeria associated with high morbidity and mortality are
