Which two external parasites found on dogs belong to the arachnid family?

• A. Ticks and Mites
• B. Fleas and Lice
• C. Ear mites and lice
• D. Flukes and tapeworms

Answer: (A)

Ticks and mites are arachnids, part of the same group that includes spiders and scorpions. On dogs, these external parasites share eight legs as adults and lack antennae, which helps distinguish them from insects like fleas and lice that have six legs, three body segments, and usually antennae. Ear mites are also arachnids, but the pair that best fits two arachnid external parasites commonly found on dogs is ticks and mites. Flukes and tapeworms are flatworms and are not arachnids, and they’re typically internal parasites rather than external.
