Myiasis
Issue Description
Occurs at the tip and folds of the ear in dogs. It is caused by bites of the stable fly, Stomoxys calcitrans.
Other Names
Fly Strike Dermatitis, Blowfly Strike
Causes
The flies' bites result in severe irritation to the skin, producing bloody crusts and scabs.
Increased Risks
Increased risks for developing Fly strike include:
Animals who spend the majority of the time outside
Animals with diarrhea
Animals with vomiting
Animals with scratches or sores
Animals with matted hair
Animals with skin conditions
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 the vet.
Prognosis
Good, unless maggot infestation is severe. The ear may be scarred and remain thickened.
