Studies of a foxhound pack and gundog kennel in Clwyd, Wales showed 47 of 162 foxhounds (29%) and six of 25 gundogs (24%) to be infested with cestodes. Taeniia species were found in both groups, T. hydatigena being most common. Echinococcus granulosus and Dipylidium caninum were found in hounds only. The husbandry of the dogs was investigated and close relationships were found between diet, worming procedures and cestode infestation. These dogs play an important role in disseminating cestode eggs in the environment. Recommendations for control of the problem are made. Foxhounds and other hunting dogs play a particularly important role in the life-cycle of cestodes because their diet frequently includes uncooked carcasses and because they hunt over large areas of countryside, facilitating the widespread dissemination of infective eggs.
The results of a survey of 51 farms in Clwyd carried out between 1981 and 1983 to elucidate the prevalence and epidemiology of dog cestodes are reported. Taeniid species were obtained from 24 (17.1%) of the 140 dogs which purged. Taenia ovis and T. hydatigena appeared to depend largely on dogs scavenging from carcasses for the perpetuation of their life-cycles, whereas T. multiceps was found only in dogs on two farms where sheep heads formed the main diet of the dogs. Dog husbandry in relation to cestode epidemiology is discussed, and recommendations for control are made.
