Dermanyssus spp (chicken mite) are an hematophagous parasitic mite which sometimes infests dogs and rabbits, which are an accidental host[2].

These mites are frequently found on birds and in bird nests. The life cycle can be completed in a week or less and adults can survive starvation for months.

Species which are pathogenic to dogs include:

  • Dermanyssus gallinae[3]

These mites usually cause pruritus and secondary dermatitis due to scratching by the dog. Clinically, infestations present as 'walking dandruff' (similar to [[Cheylitiella spp]. Their importance as disease vectors in unclear[4].
