I don't use the spiral kind; I've heard too many people say that their dogs eat them too fast. I think they are more for puppies are ultra-tiny dogs. I don't use Bully sticks as a food item, but as a chewing item a substitute for bones. I really think dogs need to chew and my two chew about an hour a night while I'm holding their sticks. A 6 inch bully lasts over a week, so they are eating less than an inch a night. My boys can chew as long as they want, but seem to tire after about an hour. |
