I don't give my Roxy any Greenies or Rawhide or anything like it... Roxy had so many problems with her bowels and throwing up when I would give her just a little bit... Her Foster Mom (breeder) used to give her Rawhides... and they always knotted up her belly and she ALWAYS had a growling belly. I took them off of her, and now she just gets regular stuff... (Eukanuba, Natural Balance, Canine Carry Outs, Cesar, beef, chicken... ) and she hasn't had any "belly growling" problems ever since... Plus, she only throws up or gets diarrhea very rarely.... (only when I tried changing her diet) But, NO GREENIES!!!
Oh, she gets those Breath Bones too once in awhile... those are good
