Abstract Background The primary aim of this study was to obtain more knowledge about the occurrence of Cryptosporidium and Giardia in young dogs in Norway. The occurrence of these parasites was investigated in a longitudinal study by repeated faecal sampling of dogs between 1 and 12 months of age litter samples and individual samples . The dogs were privately owned and from four large breeds. Individual faecal samples were collected from 290 dogs from 57 litters when the dogs were approximately 3 4 6 and 12 months old. In addition pooled samples were collected from 43 of the litters and from 42 of the mother bitches when the puppies were approximately 1 and or 2 months old. Methods The samples were purified by sucrose gradient flotation .
