Module 1 of 8 · 8–12 minutes
Recognise ticks and understand scale

Tick awareness matters for dogs and households because ticks can affect animal health and can also be carried into shared environments. Some ticks transmit infections, including Lyme disease in relevant regions and species. Risk varies, and most encounters do not establish illness. Use veterinary advice for the individual animal and human health guidance for people; never diagnose from a tick photograph or course result.
Ticks are arachnids, not insects. Larvae have six legs; nymphs and adults have eight. Species, stage, sex and feeding state change appearance. Ticks can be extremely small, and a photograph cannot show whether one carries infection.
