The Internet is a wonderful tool that has revolutionized the way in which we obtain information. With a few keystrokes, you can find anything from how to tie a Windsor knot to free advice on treating any ailment.

But beware. The quality of medical information on the Web varies widely, both for animals and for people. Much is backed by scientific evidence, but some by only opinion and conjecture.

Consider the source and look for bonafide expert guidance from veterinarians and physicians. Websites associated with universities and teaching hospitals are a good place to start. Major drug companies also provide reliable information on the products they manufacture, but watch out for Internet sales pitches.

Most importantly, remember that no website can replace the hands-on expertise of a knowledgeable and caring health professional. After all, you get what you pay for.
