1. The penis of an animal, especially a bull.
It is also known, at least since 1523, especially in the combination "bull pizzle", to denote a flogging instrument made from a bull's penis - compare bullwhip.
Pizzles are almost exclusively used/produced today as chewing treats for dogs. They are a fibrous muscle, and are prepared by cleaning, stretching, twisting and then drying. The result is a very hard, 80–100 centimetres (30–40 in) long brown stick, which is then sawed into pieces appropriate for the size of the dog.
The pizzle of a bull was commonly rendered for use as glue.
In addition to being used as a dog treat, pizzles are also eaten by humans for their health benefits such as being low cholesterol and high in protein, hormones, vitamins and minerals such as calcium and magnesium. Pizzles for human consumption are prepared either by freezing or by drying. Scottish deer pizzles are thought to boost stamina and were used by Chinese athletes at the 2008 Summer Olympics. Pizzles can be served in soup, and if they have been dried they can be turned into a paste. Pizzles may also be mixed with alcoholic beverages or simply thawed (if frozen) and eaten. In Jamaica, bull pizzles are referred to as "cow cods" and are eaten as cow cod soup. Like many pizzle-based foods, cow cod soup is claimed to be a male aphrodisiac.
Stumpy has gotten a little fussy when it comes to chewies. For some reason there are unchewed rawhides, booda bones and other assorted chews all over the house. But the pizzles still hold her interest.
Twenty minutes later, she'd barely made a dent.
I traded the pizzle for her dinner, at that point. And I'll pick up some more of these when I go to town.
By the way, These were a generic no-name brand. You might be more familiar with the Bully Stick brand.
