The most common forms of external parasites of dogs are usually lice, fleas, ticks and mites. This study
recorded 11.88% dogs infested with ticks, 9.84% with flea, 0.90% with lice and 3.76% with different types of
mange (Table 1). It appears from the Table 1 that all age groups of dogs are affected with lice, tick, flea and
mites but only mange mites showed significantly (p > 0.05) higher prevalence in dogs above 36 months (2.34%)
in comparison to aged between 7 to 36 months (1.36%) and up to 6 months (0.05%) age groups (Table 1).
However, higher prevalence rate of fleas and mange mites have been reported elsewhere (Rodriguez-Vivas et al.,
2003; Durden et al., 2005) who reported Demodex canis (23.0%) as a most frequent mite, followed by Sarcoptes
scabei var canis (7.0%) and Otodectes cynotis (3.5%) in Mexico. Seasonal frequency of ectoparasites infestations
has also been reported (Shoorijeh et al., 2008).
