Origin of the domestic dog haplotype designated as S805 (28,000 YBP) from the Yana River was one mutation away from another haplotype S902 (8,000 YBP) that represents Clade A of the modern wolf and domestic dog lineages. Closely related to this haplotype was one that was found in the recently-extinct Japanese wolf. Several ancient haplotypes were oriented around S805, including "Canis c.f. variabilis" (360,000 YBP), Belgium (36,000 YBP – the "Goyet dog"), Belgium (30,000 YBP), and Konsteki, Russia (22,000 YBP). Given the position of the S805 haplotype on the phylogenetic tree, it may potentially represent a direct link from the progenitor (including "Canis c.f. variabilis")
Ticks of domestic animals create a potentially fatal inflammatory crisis of the blood. The name redwater (coloured urine) derives from the hemoglobinuria caused by the destruction of red blood cells infected with the merozoite stage of "Babesia"; anemia results from the same destruction. Horses suffer babesiosis or biliary fever when infected by "Ba. equi" or "B. caballi". This occurs in many countries where vector ticks are found, such as "R. e. evertsi", "Hy. truncatum", and "D. nitens". Dogs are at risk from severe infection with "Ba. canis" and its subspecies, transmitted by the dog ticks "R. sanguineus", "D. reticulatus", and "Ha. leachi". Domestic cats
