Flea bite hypersensitivity is a common cause of pruritus and secondary infection in dogs and cats. It can be easy to prescribe flea prevention and assume you have ruled it out. But some cases need a little more detail when collecting history and providing discharge instructions...How is the owner giving the flea prevention?Are other dogs and cats on quality fast flea prevention?What frequency is owner giving the prevention?Find out about a recent case I had where the pet was on great flea prevention... but the other pets in the household weren't. A big difference occurred with just a small change.
