Angiostrongylus vasorum infection was diagnosed in six dogs by the ide
ntification of larvae in sputum or faeces, or by the identification of
adult worms post mortem. In another dog strong evidence of the condit
ion was obtained but no parasites were identified. In four cases the m
ain clinical signs were coughing and dyspnoea, but one dog had exercis
e intolerance and no history of coughing. One dog in which larvae were
found in the faeces had no clinical signs that were related to the in
fection. Another dog had flaccid hindlimb paralysis and forelimb hyper
metria - clinical signs of the disease which have not been reported pr
eviously. Four of the cases came from south Wales, one of them being t
he first case of the infection to be reported from this area.
