A small white blob doesnt sound like a tick to me. They are usually greyish and about 5mm diameter. If it looks like one dont try to pull it off, burn it etc. Try a drop of methelated spirit and wait for it to drop off by its own accord. Ticks have little things that bury into the skin which are very delicate and will be left in and become infected if you try to pull it off or touch it with a hot match which makes them exlode!! I have had ticks on my gundogs, cats, ferrets, myself and even an old girlfriend!
