Animals with weakened immune systems
Symptoms The ears, especially at the margins, will have
painful bumps, sometimes with scabs or bleeding. Common clinical signs
include head shaking and scratching at the ears.
Treatment Any dog affected by fly strike should be taken
to a vet. The vet can shave the hair from around the scabbed areas.
This helps to dry it out and keep it clean. An application of
antibiotic ointment, which sometimes contains an anti-inflammatory, is
smeared on bitten parts of the skin. This helps to clear up any
infection and soothes the injured region.
A number of veterinary solutions are available to help with this. Most
flea treatments are simply insufficient for the prevention of fly
strike. Some horse fly treatments will work well enough for dogs.
Veterinary advice is paramount as to the most suitable medication for
your pet. Any treatments advised or supplied by your vet must be
carried through as per the package instructions, or at the advice of
Prognosis Good, unless maggot infestation is severe. The
ear may be scarred and remain thickened.
