Clinical signs observed and the study of blood picture. The percentage of infection with eggs and oocysts of endoparasites in stray dogs and guard dogs were 78.57%, 27.27% respectively Eggs of Toxocara canis 40.47%, eggs of Toxascaris leonina 30.95%, eggs of Taenia spp 16.6%, oocysts of Isospora spp 7.1% and Cryptosporidium spp 11.9% were diagnosed in stray dogs. The eggs of Dioctophyma renale appeared 4.76% in faeces of stray dogs. In guard dogs, eggs of Toxascaris leonina 27.27% were also diagnosed.

In pet dogs, only Rh. sanguineus 16.6% was recorded. Mixed infection with different endoparasites and ectoparasites was most common in stray and guard dogs 76.19%, 40% respectively. Conclusion was made that the highest percentage of endo and ectoparasites were in stray dogs.
