    Hints

    1) Sarcoptes scabei is an exclusively human pathogen.
    2) Abandoning the dog will stop the man's problem but the dog's problem will become worse.
    3) The loss of hair on the dog's back holds the key.

    Anybody who keeps a dog or cat and cares for it, should know the answer as it is a very common problem.

    Ans: dog flea.jpeg Bite

    Discussion :
    The principal sign of flea infestation in an affected animal is the presence of dried concretions of flea faeces on the animal’s coat.
    Some animals will also have signs of fl ea allergy dermatitis, with areas of crusting and alopecia, most frequently on the lower back and the base of the tail.

    The man has the lesions very characteristically on the lower legs, as they r the closest part to the dog (when the man is with his best friend) and the fleas can easily hop on

    man and dog.jpg watching tv.jpg etc.

    Now to answer the bonus question - let's consider a scenario

    let's say that the man has dozed off and his girlfriend and dog r watching tv and suddenly there is a fire in the house. The man's gf (???) will run out of the house ( as if there is no tomorrow ) but the dog will first alert the man and ensure that he leaves first ( now that's friendship )
    (-8

    I am assuming that lepersan meant flea bite, while referring to chip bite....so he gets the credit for this challenge.

    Moral of the story - there are many dermatological mimics and just like the larva and pupa of many widely varying species can look alike, so can many dermatological conditions in various stages of evolution of the primary lesion or the secondary lesion.

    So next time u r faced with a case of Rx resistant scabies ( child or adult and in case of child the lesion could be on the hands and trunk in characteristic scabies distribution ) look for the web spaces and if they are spared, then b alert to the possibility of a pet in the house.
