Synosternus spp are a common hematophagous parasitic rhopalopsyllid flea which is commonly found on rodents but has been reported on hunting dogs or dogs living in close proximity to domestic rabbits.
These fleas, primarily a parasite of small mammals, infect dogs as an accidental host.
Species which are pathogenic to dogs include:
- Synosternus pallidus
Clinical signs include pruritus and localized dermatitis associated with flea activity.
Treatment is usually effective with a range of insecticidal drugs such as fipronil and permethrins.
