This trombidioid larval mite mite resides in the hair follicles of dogs, and has been reported in France. Foxes are considered to be the natural host for the larval stage, and dogs a permissive but occasional host.
Pathogenic species include:
- Straelensia cynotis
Clinically affected dogs displayed scattered, small (1 to 3 mm in diameter), pale, firm skin nodules, variable in distribution but always affecting the dorsal regions of the head and trunk. In some dogs, they can be distributed over the whole body.
Diagnosis is based on clinical signs and identification of the parasite in the dermis obtained from skin scrapings.
Symptomatic treatment may be required in cases of severe pruritus.
