cats and dogs are different species but many higher-allergic children are allergic to many animal danders. to be sure just ask the medical provider for a blood test for cat dander as well. longer-haired dogs have more dander than the bald ones and there are some breeds that shed very little and are tauted as "hypo-allergenic" dogs but i am skeptical. the sex of the dog should not make a difference. i never met a child that was only allergic to male dogs and not females etc. w when an allergic person "reacts" and starts showing signs of allergy (itching hives sneezing wheezing swelling etc. ) we often blame the last thing they did. something they ate touched inhaled or encountered but that is only circumstantial. a child with allergies typically is allergic to many things including some things that were not even tested. if you are being pressured to get a pet. a dog or a cat. it is best to be tested first before you acquire and animal and become attached to it.
what is the likelihood that a 4 year old child allergic to cats will also be allergic to dogs? . does it matter whether the cats/dogs are male or female? are some breeds of dog more allergenic than others? if the symptom includes a puffy face which is not usual for her cat reactions could this be due to exposure to a dog or other allergenic?
