Dogs and history: blood transfusions

A little bit of history in this post.  Did you know that the dog had a key role in the development of blood transfusion technology in humans?

Unfortunately, this is a story of animal experimentation.

In the early 1600s, an English physician named William Harvey explored the circulatory system and declared that ‘blood must continuously circulate.’  For the next 50 years, more work was done to understand the circulatory system.  Dogs were unfortunately chosen for animal experimentation and they were injected intravenously with a range of fluids including opium, wine and ale.

In 1665, English physician Richard Lower drained the blood out of a dog almost to the point where it had no blood volume left and was on the verge of death.  He then took a larger dog and replaced the blood supply.  (Poor dogs)
