The best Bully Sticks for Dogs are one of the favorite dog chew stick treats. One definition in Wikipedia used to say that “Bully sticks in general are generally prepared from a fibrous muscle of beef.  This is cleaned, twisted and stretched.  It is then dried in the sun, baked in an over, or smoked to dry it.  Wood smoking gives the stick a smoky flavor.  The result is a very hard, yard long brown stick.  It is sawed into lengths right for various sizes of dogs, generally 6 or 12 inches.”

That was maybe 6 months ago.  Wikipedia has corrected its description, and now, along with virtually everyone else, gives the answer to “What are Bully Sticks Made Of ?” as simply “bull penises” !  And this is the right answer.


Best Bully Sticks Brand

In general, most definitions of bully sticks for dogs use the word “pizzle” instead of “penis”.  Either way, of course, it is 100% beef.  So Google’s answer of “Beef” is technically correct.  But a more thorough answer is as follows, as described in BestBullySticks.com — a company that is the source of our number one recommended bully sticks for dogs, and also the best selling bully stick on Amazon:

“The best Bully sticks usually are items made from a singe ingredient, which at its best is 100% free-range, natural bull pizzle.  (Pizzle=penis). Some sellers vendors will create manufactured products that look like bully sticks, but are made from all sorts of chemicals. Also, make sure that the supplier you are buying from doesn’t  add strange chemicals to the bully sticks to take out odor or help to preserve the treat. Frequently manufacturers of lower quality bully sticks will process the treats in chlorine or other strange chemicals to take out or cover up the smell of a poorly made product.”

We suppose “pizzle” this is more delicate or politically correct, or at least does not bring up chuckles when one answers “What are Bully Sticks Made Of ?”

It is an accepted idea that you get the best bully sticks from US or South American steers.  Some beef pizzle from China and India have suspect quality.  Some are not always prepared well.  This may result in your dog getting sick.

An important thing about the best bully sticks is how high they are in calories. Researchers at the the University of Guelph and at the Cummings School of Veterinary Medicine at Tufts University and looked at 26 bully sticks obtained from suppliers in Canada and the United States.

Tests of the bully sticks for dogs showed that they contained between 9 and 22 calories per inch.  This is an average of 15 calories per inch, or about 88 calories per 6-inch stick on average.

Lisa M. Freeman, DVM, Ph.D., says, “While information about calories is not always required on pet foods or pet treats, findings like this reinforce that pet owners and vets should be aware of bully sticks and other pet treats which can be a source of extra calories in a dog’s food.”

Dog Food Advisor calculates that an average 30-lb dog needs 780 calories.  A low-activity dog only 640.  So this means that for a small dog, one of the bully sticks for dogs is about to 11%-14% of the dog’s calorie needs for a day.  That is a lot!  So be careful!

That said, in general bully sticks for dogs are usually really safe and a favorite for the most enjoyable dog treats.  Bully sticks have:

  • High protein
  • Magnesium and Calcium
  • Vitamins
