Canine  parvovirus  (CPV)  and  canine  influenza  virus  (CIV)  are  highly  contagious  virus  infecting members of the canine family including dogs, coyotes, foxes and wolves. The research work was carried out to determine  the  prevalence  of  CPV  and  CIV  in  dogs  (str ay  and  pet  dogs)  in  Dhaka,  M ymensingh,  Feni  and Chittagong districts by using RapiGen CPV and CIV Ag test kit. Fecal samples were collected from 50 dogs of different age and sex from different spots of Dhaka and Chittagong districts. Nasal fluid samples were collected from  50  dogs  of  different  age  and  sex  from  different  spots.  The  samples  were  tested  with RapiGencanine parvovirus Ag  test  kit  and RapiGencanine influenza  Ag  test  kit.  Overall  prevalence  of  CPV  in  pet  dogs  was 22%  and  in  stray  dogs  was  30%.  The  prevalence of  canine parvovirus in  relation  to  age was  gradually decreasing with higher age group and the prevalence was 28% in 1-6 months age, 16.66% in 7-12 months age group 11.11% over 18 months age group. The prevalence of canine parvovirus was significantly higher in male (24.13%)  than  that  in  female  (19.04%).  All  samples  showed  negative  test  result  for  canine  influenza  virus. Prevalence  of  canine  influenza  virus  infection  were  00.00% in  all age  groups  and  sex.  Overall  prevalence  of CIV in all pet and stray dogs were 00.00%.
