The anthelmintic control for dogs and cats is not only indicated for curative treatment of clinically diseased animals, but also for the control of zoonotic infection of humans. In addition to the protection of the individual animal against helminth infection, the decontamination of the environment of infective stages s a major goal of parasite control. The prevalence and pathogenicity for men and animals of roundworm (Toxocara spp.) and tapeworm species (Echinococcus spp.) indicate that these are pathogens of major importance in Germany. The treatment of all dogs and cats with a broad-spectrum anthelmintic at least every 3 months is recommended for Germany. Less frequent treatment is ineffective. Treatment every 3 months can only be replaced by at least monthly faecal examinations (followed by therapy in case of a positive result). The shedding behaviour of the endoparasites precludes less frequent faecal examinations. This would increase the risk of false negative results. In certain circumstances, anthelmintic control has to be intensified, e. g. for dogs and cats with flea infestation, measures for the control of the tapeworm Dipylidium caninum has to be included. The regular treatment schedule for pets in close contact to children, notaly pregnant animals and dams in oestrus, has to be adapted to the specific situation. Dogs and cats living together in households, kennels or catteries, and those with access to so-called common dog-greens are under increased risk of parasite infections.
