Ugh, I had no clue what bully sticks are before I read this thread. 

 Gross! 
 
Still, I didn't have too much of a problem with Bailey trying some since everyone's babies love them so much. I ordered 2 from dog.com while I was putting in an order. 
But OMG the ones I got smell so bad! She only had it for 5 minutes last night, and she loved it, but I was sitting next to her eating so I couldn't take it! Even after I took it away her face and paws smelled! It smells like nasty fertilizer. So gross! I spent $5 on the 2 I ordered but I don't even know if I will ever give them to her again.  
Maybe we will have to try again with the no smell ones, but to me the smell is far worse than knowing what they are.
