flea allergy dermatitis
the inflammatory lesions and self-trauma caused by a hypersensitivity to flea bites. In dogs, this is usually centered on the back over the lumbosacral spine, around the tail base, and inside the hindlegs. Secondary infection is common.
flea antigen
see flea antigen.
flea collar
a collar (or tag) impregnated with insecticide, hung around the animal's neck. There is a slow release of the active compound, either as a vapor or powder, to kill ectoparasites on the body.
flea collar dermatitis
a contact dermatitis in dogs and cats caused by the insecticide-impregnated polyvinyl chloride collars marketed for flea control. Although the initial and most severe skin reaction occurs where direct contact is made, surrounding skin may also become involved. Correct use of the collars minimizes this risk.
flea dip
any of the external parasiticides applied to dogs as a rinse; dipping is not a practical form of application in most companion animals.
