The close interaction between humans and dogs increases the zoonotic potential of pathogens, increasing the urgency of addressing this overlooked vector-borne health risk, especially in developing regions. This study sought to identify tick-borne zoonotic pathogens by collecting ticks from dogs and screening for\n                    <jats:italic>Ehrlichia<\/jats:italic>\n                    species, a group known to pose significant yet often neglected health risks to both humans and animals, particularly in the northern area of Khyber Pakhtunkhwa (KP), Pakistan. Ticks were collected from dogs in the Mardan and Dir Lower districts of Pakistan from June 2024 to May 2025. The collected ticks were morphologically identified and processed for molecular identification using 16S ribosomal DNA (16S rDNA) and cytochrome c oxidase (\n                    <jats:italic>cox1<\/jats:italic>\n                    ) sequences for ticks, and 16S rRNA and\n                    <jats:italic>dsb<\/jats:italic>\n                    sequences were used for their associated\n                    <jats:italic>Ehrlichia<\/jats:italic>\n                    spp. Among the 223 dogs observed, 147 were infested with ticks, resulting in an overall prevalence of 66%.\n                    <jats:italic>Rhipicephalus<\/jats:italic>\n                    ticks\u2019 infestation were more common in female dogs (91\/113, 80.53%) than in male dogs (56\/110, 51%). The occurrence of adult females was highest (173\/432, 40%), followed by males (158\/432, 36.57%) and nymphs (101\/432, 23.37%). Two tick species were identified:\n                    <jats:italic>Rhipicephalus haemaphysaloides<\/jats:italic>\n                    and\n                    <jats:italic>Rhipicephalus<\/jats:italic>\n                    sp., which was identified as a member of the\n                    <jats:italic>Rhipicephalus sanguineus<\/jats:italic>\n                    species complex. This was confirmed by 16S rDNA and\n                    <jats:italic>cox1<\/jats:italic>\n                    sequences, which showed 99\u2013100% maximum identity. In the phylogenetic trees,\n                    <jats:italic>Rh. haemaphysaloides<\/jats:italic>\n                    clustered with the same species reported from Pakistan, while\n                    <jats:italic>Rhipicephalus<\/jats:italic>\n                    sp. grouped with\n                    <jats:italic>Rhipicephalus<\/jats:italic>\n                    sp. morphotype III from Pakistan and India. Regarding their associated bacterial species, such as\n                    <jats:italic>Ehrlichia<\/jats:italic>\n                    spp., they were detected in both\n                    <jats:italic>Rhipicephalus<\/jats:italic>\n                    sp. and\n                    <jats:italic>Rh. haemaphysaloides<\/jats:italic>\n                    based on 16S rDNA and dsb sequences, which revealed maximum identity with\n                    <jats:italic>Ehrlichia minasensis<\/jats:italic>\n                    and\n                    <jats:italic>Ehrlichia<\/jats:italic>\n                    spp., respectively.
