•This study was determined the prevalence of Toxocara eggs on hair and in faeces of healthy owned 100 dogs and 100 cats.•The prevalence of Toxocara eggs in faecal samples was lower than hair samples of cats and dogs.•We found embryonated Toxocara eggs on cats’ hair. This result is different when compared with similar previous work.•We also found; Fasciola sp., Taenia sp., D. caninum, T. leonina, Dicrocoelium sp. eggs in dogs’–cats’ hair or faeces.•Sedimentation and flotation techniques were tested for efficiency and suitability for routine use. This study was undertaken to determine the prevalence of Toxocara eggs on hair and in faeces of healthy owned cats and dogs and to make comparisons between data (sex, age, host factor, etc.) collected from dogs and cats. Toxocara eggs were found on the hair of 14% of 100 dogs and 22% of 100 cats. In total, 58 and 136 eggs were recovered from the hair samples of examined cats and dogs, respectively. Of the total number of eggs, 2 were classified as embryonated in cats. One of the eggs recovered was embryonating in dogs. The maximum number of eggs was found in the tail bottom of cats (28 eggs) and dogs (58 eggs). As well as finding Toxocara eggs in dogs and cats hair, we also found eggs of some helminthic parasites; such as Dicrocoelium sp., Fasciola sp., Taenia sp., Dipylidium caninum and Toxascaris leonina. In addition, faecal samples of same dogs and cats were also examined by two techniques (centrifugal flotation and sedimentation): Toxocara eggs were found in 5% and 13% of dogs and cats faeces, respectively. But, 14% of the dogs and 22% of the cats were positive for Toxocara eggs on hair. The prevalence of eggs in faecal samples was lower than those detected from hair samples (P<0.05). Two techniques for recovering Toxocara eggs from faecal samples were tested for efficiency and suitability for routine use. The results were expressed as the percentage rate of recovery of Toxocara eggs in positive faecal samples. The recovery rate was better with the method of sedimentation than with the method of flotation (P<0.05). This study indicates that dogs and cats without internal infections were shown to have eggs on their hair and so uninfected animals also pose a threat in terms of the eggs present on their hair, albeit a small risk.
