PLEASE ANSWER!! what are these bugs?

i saw one yesterday on my arm. it jump off really quick. then i saw it again and i caught it and popped it. blood came out when i popped it. then this morning, i saw another on my leg and popped it. they're little red bugs that jump. they left red dots on my feet before (small and flat) sometimes itchy but not really. are they lice? my head isnt itchy though. or ticks/flees? my brother's stupid girlfriend use to bring her uglyazz dog over and that thing had flees.
