Any dog can have any amount of health problems, guest. The best way to find out if your dog has fleas is to comb it over a sheet of damp blotting paper/kitchen towel. If the black specks spread as red, they are flea droppings and your dog has fleas. Kennelling has nothing to do with it (unless you are kennellling on straw or hay, both of which are notorious for harbouring fleas). Perhaps you could register and ask a more specific question.
