Also known as: '''''Dog biting louse
''Trichodectes canis'' is a [[Chewing Lice|chewing louse]] of dogs.
==Introduction==
''Trichodectes canis'' is a '''[[Chewing Lice|chewing louse]]''' of dogs. It is '''very host-specific''' and cannot infest any other species than the dog.
It can have serious effects in '''puppies and older, debilitated animals'''.
''T. canis'' can also act as an intermediate for the tapeworm ''Dipylidium caninum''.
The lice are transferred by '''direct contact''' between animals, or via '''shared combs and brushes'''.
==Identification==
The adults are '''small, yellow lice''', measuring around 1.5mm in length. The head is '''broader than long''' and the antennae are three-segmented, short and exposed. The legs are stout and their tarsi bear single claws, with which they tightly grasp the hair of the host. The abdomen has 6 pairs of spiracles on segments 2 to 6 and many rows of large, thick setae.
==Life Cycle==
The female is capable of laying several eggs per day for approximately '''30 days'''. The eggs then take around 7-14 days to hatch, and then give rise to '''three nymphal stages'''. The nymphs mature into reproductive adults within about 2 weeks.
The egg-to-adult life cycle requires about '''30 to 40 days'''.
==Clinical signs==
It is more commonly found on the '''head, neck and tail''' attached to the base of the hairs.
Lice often congregate around body openings or wounds, seeking moisture.
Typical signs of infestation include: '''intense pruritus, scratching, biting''', sleeplessness, nervousness and a matted coat.
===Life Cycle===
Damage to the skin results in inflammation, excoriation, alopecia and secondary bacterial involvement.
==Diagnosis==
Diagnosis is made on the basis of clinical signs and identification of lice in the coat. This can be done by collecting '''tape strips''' or '''coat brushings''' which are examined under the microscope.
==Treatment==
Lice spend their '''entire life-cycle on the host''' and are readily killed by permethrin, carbaryl and fipronil.
These antiparasitics should be applied '''twice, 14 days apart'''.
