Ticks

Do I have to worry if I pulled a tick off our Pomeranian and the head broke off and is still inside?

Nevermind.

Even when you remove the tick properly, its multi-barbed hypostome usually remains embedded in the skin. If you have carefully removed the tick's head and body, the hypostome itself is pretty much harmless and will eventually fester out like a tiny splinter.
When there are only one or two tick bites, physicians sometimes dig out the hypostome using a big hypodermic needle or excise that section of skin with a biopsy punch. This may or may not be a good idea on people, but is certainly impractical on pets.
