    Abstract: The researchers analyzed the possibility to stop the estrous 
  in bitches through the hormonal treatment. For this reason, during 2007-2009 
  sixteen bitches of different ages and breeds being in anestrous period were 
  selected from clinics of Tirana district excluding bitches with health problems. 
  For every case, the appearance of estrous cycle is determined through anamnesis, 
  clinical examination and vaginal cytology. As a hormonal treatment for stopping 
  cycling Proligestone (Covinan<SUP>&reg;</SUP>, Intervet) was used. The bitches 
  were treated with injection in doses 20 mg kg&#8226;<SUP>1</SUP> or 0.1 mL kg&#8226;<SUP>1</SUP> 
  weigh SC. The statistical analysis of the data shows that the estrus appears 
  190&plusmn;14 days after the last treatment. Collateral effects were found after the 
  last application of the hormonal treatment. The systemic application of the 
  hormonal sub-stances for the prevention of the estrus results to be efficient, 
  however other risk factors should be additionally considered.
