Who knew? Bull penises are high in calories
And more than half of all consumers who buy them for their dogs aren’t aware that they are made from the penises of bulls.
Perhaps even more astounding, about four of every ten veterinarians didn’t know that, either.
The study, which pointed to some health concerns when it comes to bully sticks, also known as pizzles, was published this month in the Canadian Veterinary Journal.
Researchers at the Cummings School of Veterinary Medicine at Tufts University and the University of Guelph examined 26 bully sticks purchased in the United States and Canada. A random sampling of those determined they contained between nine and 22 calories per inch.
That’s about 88 calories per six-inch stick, less than 10 percent of the recommended caloric intake per day for a 50-pound dog.
Slightly more alarming was the study’s finding — based on tests on all 26 bully sticks — that nine were contaminated with bacteria. One was contaminated with Clostridium difficile; one with Staphylococcus aureus (MRSA), a type of staph bacteria that is resistant to certain antibiotics; and seven were contaminated with Escherichia coli.
The researchers advised pet owners to wash their hands after touching such treats, as they would with any raw meat diets.
Based on an online survey conducted as part of the research, only 44 percent of pet-owners, and only 62 percent of veterinarians, were aware bully sticks were bull penises.
Twenty-three percent of the respondents fed their dogs bully sticks.
