My dog LOVES those bully sticks...aka pizzles. They are the male part of the bovine...you can google the word pizzle for the "ingredient" of your dogs favorite treat...LMAO!

Here is a link that might be useful: pizzle definition

I know...I found lots of things about pizzles....the only recipe I found was basically the same as how to make beef jerky. Seems too easy. Anyone know if they should be seasoned with anything?

Making them yourself? I have no idea where a person would get raw bull thingies? You could just make your own jerky out of a meat that is ok for the dog to eat. I would say that you would want to use no seasonings. That would be the most healthy.

I have baked liver bits, dried them out and my dog loved them. Same with chicken slices.

I like the Bil-Jacs liver training treats at Petco. The regular size is a bit over half an inch, the Little Jacs size is about 1/3 of an inch. They cost about three to four dollars per bag. I've only seen two dogs that did not like them.

I have no connection to Bil-Jac or Petco. The grocery stores near me do not carry them.
