Straelensia cynotis is the causal agent of a parasitic dermatosis recently reported in three dogs, The lesions were to be found mostly on the animal's face, and possibly on the back and/or ventrum. No acaricide treatment proved to be effective. Cure was observed as the parasites were slowly resorbed into the lesions (from 6 to 12 months). Since dissection inside nodules is random, the histo-pathological images appear to be specific, even when the parasite section is not included in it. At present it would appear that this dermatosis has been reported in several new localities (departements) in France. This development may be explained by ecological changes together with more frequent interaction between the dog and wildlife, since the parasitic population in the environment increases at the same time as the reservoir of wildlife. Generally speaking, the change of host is slow for the cycle to be completed, In this instance it is interrupted, which would seem to suggest an abnormal host or a closed-end development cycle.
